Y-chromosome haplotree growth

World’s largest Y-DNA Haplotree from FamilyTreeDNA (Image generated using iTOL; FTDNA Blog)

Male part of humankind has been having an important role in identification of people by their origin and belonging. Often they were seeking for a new land, trade or better resources, while women and children stayed in camps. Therefore, they were more mobile also in the time when bare foot was the only means of travelling. Those facts are important for understanding the meaning and interpretation of human haplotree, which is created based on testing of Y-chromosome (attribute of man).

Family Tree DNA is a pioneer in DNA testing specialized for genealogy (hosting a Slovenian origin project among hundreds of others), starting with commercial test soon after the human genome was first sequenced in 2003 (The gaps of some DNA parts have been sequenced only recently). Family Tree DNA is actually a pioneer of genetic genealogy with systematically established the world’s largest DNA database for genealogy, comprising not only atDNA, but also Y-chromosome and mitochondrial DNA records. Nowadays, their partner Myheritage, with which they share the testing laboratory, has larger database with atDNA results, but Family Tree DNA remained the leading company with their Y-chromosome and mitochondrial DNA records, which give specific ancestry information of direct lines. You are in the best hands when you test with MyHeritage and Family Tree DNA, as the atDNA results are exchangeable and both interprete the results obtained. You have to bear in mind only that your biological sample sent to Family Tree DNA for atDNA testing (Family Finder), will be kept for further purchases of tests like mtDNA and Y-chromosome DNA. If you send it to MyHeritage, it will be discharged after obtaining their results.

Family Tree DNA is well known for their work with National Geographic on the Genographic Project (2005 – 2019). This was the project with first attempt to build the humankind family tree and interpret migrations for last 200,000 years based on analysis of STR markers on Y-chromosome. I was inspired by book The journey of man (Spencer Wells), which introduced the DNA testing and haplogroups to me. At that time they tested very little on SNP markers (single nucleotid polymorphism) and focused more on STR markers (short tandem repeats).

SNP as genetic marker is a change in the sequence of nucleotides in a DNA chain that indicates a particular phenotype (like hair colour). In genealogical genetic analyses, they determine the matching of SNP genetic markers among descendants (SNP means change in a single letter of DNA alphabet A, C, G, T). A genetic marker means a physical location on a chromosome (locus). Also STRs are used as genetic markers. For example the Y-DNA67 test is a sequence of 67 markers with short tandem repeats (STRs). To learn more about how testing of Y-chromosome evolved over time watch the video from RootsTech presentation.  

The exponential growth of Y haplotree is due to new generation technology, which is commonly named as “Big Y” and has been introduced by Family Tree DNA in November 2013 (See the table below).

Big Y analysis has changed the accuracy and level of testing of Y-DNA. However, the raw data results would not help much an average user due to lack of knowledge and equipment. We need strong scientific support of the Family Tree DNA at interpreting the testing results. Even the determination of haplogroup does not happen only automatically.  The SNP markers are carefully examined by a specialist Michael Sager who also manages the Y haplotree. He assesses incoming datasets, which are usually from Big Y results, but may be from other sources, such as academic research, and carefully builds out branches on the tree. At Family Tree DNA they say that it is a one-person job and not a role that can be filled by anyone else. For more information on that process, watch this video from RootsTech. When Big Y tests are completed, they receive the automated haplogroup assignment based on the existing tree, but no new branches will be added to the tree, and no haplogroups will be updated until Sager’s intervention. So, pay attention to your Big Y results: Your haplogroup can be updated several times during years, as the database of testers grow and new information become available. Details for some haplogroups and lineages are still missing, so those, who have tested only markers Y-37, Y-67, or similar are encouraged to upgrade to Big Y analysis to get a better placement on the global Y haplotree. Remember, that a SNP must be observed in at least two related man before it can be uploaded into haplotree as a new branch. So, unless you would like to stay with your “private variants”, contact your Y-37 matches (or similar STR results) and invite them to invest to their Big Y – to place themselves into the tree and also contributing to general benefit of humankind.

A Big Y analysis was a milestone in the Y-chromosome testing and building the global Y-haplotree. However, the genealogysts know very well, that the information on direct paternal line is very little piece of ancestry compared to all other ancestry lines. Therefore, a testing of all other chromosomes gives much more information on recent relatives of last 6 generations and also from paleo-ancestry. It is very interesting to compare our results with archeological samples and read interpretation of MyOrigins how parts of our genom show ancient ethnicities and their migrations.

However, the next milestone has been reached recently by international team of scientists, who combined genetic reports of 3,609 individual genome sequences from 215 populations around the globe to produce the largest family tree ever – it identifies nearly 27 million ancestors and origins where they lived, dating back more than 100,000 years ago (Source: A unified genealogy of modern and ancient genomes/Oxford University Big Data Institute). The authors conclude: “Whole-genome genealogies provide a powerful platform for synthesizing genetic data and investigating human history and evolution”.

Slovenian haplotrees up to genetic Adam and Eve

There is a great piece of news to share: the first 50 Slovenians are shown on a phylogenetic tree after DNA testing. We have simplified the Adam’s and Eve’s trees and even gave the names to founders of genetic tribes.

A few days ago, a new Slovenian portal for genetic genealogy has been established to help genealogists in their research. The first 50 Slovenians are shown on a phylogenetic tree after DNA testing.  The portal named GENES shows simplified global phylogenetic trees of the mitochondrial and Y chromosome DNA testing results for 50 Slovenians, who have been also verified for their grandparents’ origin by their pedigree charts published at Family Tree DNA portal, which host Slovenian origin project.
Those who tested their Y chromosome, are shown on Adam’s tree, as this test is possible only for men, who inherit Y-chromosomes from their fathers. By rule of Mother Nature, Y-chromosome remains unchanged while passing through generations. So, testing a man today unlocks a secret of his affiliation to the original tribe, in which a founding man lived hundreds thousand years ago. In genetic genealogy, descendants of this man are called a haplogroup, which has been marked by letters A to Z. For the Slovenian Y haplotree a minimal reference phylogeny for the human Y chromosome has been used. This unique system of ISOGG enables each modern nation to give those Adam’s sons names in their language. In the Slovenian haplotree, the sons of genetic Adam are: Anton, Blaž, Ciril, Dominik, Ernest, Frančišek, Gregor, Henrik, Izidor, Janez, Klemen, Lovrenc, Matija, Nikolaj, Ožbolt, Peter, Quirin, Rupert, Simon, Tomaž, Urban, Vid, Walter, Xander, Yanik, and Zaharija.

Those who tested “Big Y”, which gives a piece of final haplotype information to the man, are for now 15 out of 50 in the tree. If in the future this number is increased, Slovenians will receive better information about their prehistoric tribes. Having got this information, an individual man can place himself on the global YFull tree, which contains almost 100,000 branches. He will receive information about his specific little branch. The whole tree can’t even be well presented to the public. Specialists understand it, but not the general public. So, creating a Slovenian haplotree enables the tested man to find himself in the neighbourhood of others of Slovenian origin, as only those haplotypes are shown,  which are represented by testing result of Slovenian origin. Some foreign origin ypsilons are shown for comparison, how connected European nations are when we come to the prehistoric origin.

Human migrations from prahistoric times with indicated development of mtDNA haplogroups (A-Z and colour routes in time-scale of 1000 years before present; source: ISOGG Wiki)

Just equally to the paternal line, also a maternal direct line can be traced back into prehistoric times by testing of mitochondrial DNA, which we have in each cell independently of gender. So both, men and women can test their mtDNA, which unlocks a secret of their affiliation to the original tribe, in which a founding woman lived hundreds thousand years ago. Popularly she is called genetic Eve. By rule of Mother Nature, mitochondria of a newborn life come from a mother’s egg, to which a father contributes only genetic material.

Mitochondrial DNA  is a circular genome, contained in several copies in each cell, and remains unchanged while passing through generations, as they do not recombine.  In genetic genealogy, descendants of this first discovered woman, whose receipt for mitochondria is still in use today, are called a haplogroup. The haplogroups have been also marked by letters A to Z, as each of Eve’s daughter changed the mother’s receipt for mitochondria in single letters before passing to their sons and daughters. When the sons became fathers, they can’t share their mitochondria to a newborn life (with some rare exceptions). When the daughters became mothers, they passed their receipt for mitochondria unchanged to the next generations of children. But some daughters again changed their receipt for mitochondria in single letters before passing to their children. These changes are called mutations and are inherited by descendants, who form further branches in Eve’s haplotree. Until now, 170,000 mtFull sequences have been added to global mtDNA haplotree, from 180 countries. Though it is of utmost importance to show on Slovenian tree matches of Slovenian origin (see geographic map of mtDNA donors’ origin), which fall for sure into several international clusters on a global tree.  

The unique system of ISOGG in naming the haplogroups enables each modern nation to give those Eve’s founding daughters names in their language. In the Slovenian Eve’s haplotree, the daughters of genetic Eve are: Ana, Barbara, Cecilija, Doroteja, Elizabeta, Frančiška, Gabrijela, Helena, Irena, Jera, Katja, Lucija, Marija, Nika, Olivija, Queen, Rebeka, Sara, Terezija, Uršula, Helena Vera, Vesna, Wendi, Ksenija, Yvona, and Zora.

Some of these names are not Slovenian, as the Slovenian alphabet does not contain letters Q, W, X and Y, so foreign names have been used, which indicates Slovenian’s nature: we have always been open to foreigners, who came to our tribes to live and work. We hope that those personalised trees will bring more Slovenians to test. Which means also hope for those, who are seeking a missing paternal or maternal link from Slovenia, to find a matching man or women.

The design and the outlook of Adam’s and Eve’s trees have been developed by Slovenian knowledge of Dr Uroš Ocepek, who is developing useful web-tools for genealogy in portals Genes, PriRod and Zagorje Tree. Most data for Genes come from FamilyTreeDNA, but also from other testing sources like National Geographic, even an old test result from Ancestry, and modern whole-genome-sequencing labs. He cooperates with different content developers, who are all genealogists, like himself. In case of Genes and PriRod this is Vlasta Knapič, who is also a founder of “Slovenian origin” project hosted by FamilyTreeDNA portal and author of geographic maps with data on Y and mtDNA haplotypes. Both, Dr Uroš Ocepek and Vlasta Knapič are active members of Slovenian Genealogy Society.

Slovenian DNA Pool at SUA 2019 Convention

In honor of the Slovenian American Heritage the President of Slovenian Union of America, Ms. Mary Lou Deyak Voelk, in support of Slovenian Governement hosted genealogists Peter Hawlina and Vlasta Knapič as presenters and guests at the SUA National Convention. “Believe it, our people were reintroduced to themselves. They come from a long history of people,” she said.

On 14th of January 2018 I received an e-mail on behalf of DNA club of Slovenian Genealogy Society: “Vlasta, I am Mary Lou Deyak Voelk, President of the Slovenian Union of America.  I have been thinking about a gene pool for a long time. We are having a convention in Cleveland in 2019 and I thought this would be a great way to celebrate the organizations 94th anniversary!

I believe the way to keep the Slovenian heritage alive in the USA, is to link people with their ‘family’ back home in Slovenia, people will become interested in research, finding long lost relatives. One is my family on my grandmother’s side.  I cannot find anyone!!!”

The S.U.A. National Convention takes place every four years. This one was organized in Cleveland, Ohio with the moto: “Let’s Sing & Dance!” to highlight the musical history of Slovenians. Everybody enjoyed lively events from Thursday, June 13, starting with strolling musician, Joey Tomsick,  to Sunday, June 16, 2019, finishing with Slovenian Mass at St. Vitus Church, the 1st documented Slovenian immigrant church (1893) in the US. Beside social gatherings and Cleveland tours, with many opportunities to connect with SUA members, business and educational sessions took part. Two lectures about professional musicians, who started rising at the beginning of the 20th Century in the US, gave a great overview of music history. Especially Joe Valencic, who runs also a Polka museum in Cleveland, gave a comprehensive overview of accordion players in Cleveland, the Slovenian Capital outside of Slovenia. Two peaks of the social gathering were a celebration of the 90th birthday of the SUA official magazine Zarja with Joey Tomsick Orchestra and the Convention Banquet with the Frank Moravcik Band and speakers: Slovenian ambassador in US, Washington DC, Slovenian consul in Cleveland, Joe Valencic, and many others.

Where does a lecture on genetic genealogy fit in? We could not believe: at the very first day of the SUA 2019 National Convention in Marriott East (26300 Harvard Road, Warrensville Heights) on Thursday afternoon, just after a welcome reception! Smaller meeting room needed to be replaced by a hall where more than 120 people fit. Two speakers from Slovenia were invited: Peter Hawlina and Vlasta Knapič. Both are the main promoters of genetic genealogy in Slovenia, investing in testing and organising DNA projects within FamilyTreeDNA. Peter Hawlina is the SGS president emeritus and enthusiastic genealogist. In Hawlina group we can research among results of three generations of Hawlina close relatives and also his remote cousins.

On behalf of the Slovenian DNA Club Vlasta has recently created a project group within the Family Tree DNA portal: the Slovenian origin, to be able to assisst to and compare results of anybody of Slovenian origin, who joins the project. Beside DNA results, every record contains genealogy data, including ancestral surnames and places of origin. This new platform enables interactive communication among project members in the “Activity feed”, where a member can ask questions, share photos and ask for help in interpreting genealogy data in English. Our country name has been already years ago taken by another dual-project group based on geographic origin and surnames, run from US by Slovenian Genealogy Society International. As FTDNA project Slovenia is not really maintained and has a single unactive administrator, talks to merge both initiatives into one project – the “Slovenian DNA Pool” had started, but with no result obtained yet.

If people wish to interact with other Slovenian genetic genealogists and upgrade their DNA tests in the future (mtDNA, Y-DNA, or dual based internal project groups), they should either test atDNA at Family Tree DNA or transfer their raw data from other providers, like: Ancestry, 23andMe, or myHeritage (download) and upload the file to the Family Tree DNA. Start with creating an account and follow the instructions. Hoping to see you soon at FT-DNA Slovenian origin project group, where we can also interact in closed group activity feed with the other members of the group. Later you will be guided to provide your grandparents origin and surnames.

As there is no genetic genealogy without a classic genealogy,  the 4-steps-Slovenian-origin-2019 – exploring your ancestral origin can be followed by:

  • Identification of your ancestors, who came to the USA from Europe a Century ago from places in Austria, Hungary, Italy, or Krain, Steiermark…
  • Identification of ancestral places of origin and original family names is crucial for successful research. Learn more.
  • Create your family tree as detailed as possible. Use the official historical records as a source of information. Fill in the Pedigree_form and Family_record_form.
  • Test your atDNA or upload at Family Tree DNA. Your grandfather is closer to Slovenian origin than you. Test the olderst members of the family first. Join FTDNA.

The participants, led by Mary Lou have been satisfied with the outcome of the DNA talks and interest at the convention. “Believe it, our people were reintroduced to themselves. They come from a long history of people.” Already among the first 100 people in a project group, Mary Lou has been able to find few of her remote cousins in Slovenia. Including me. Few months later she received quite exhaustive family tree from Slovenian genealogists. The maching family name among four of us is Prijatel, which in Slovenian means a friend 🙂

Presentation: 4 Steps of exploring your family history of Slovenian origin.

Borderless Slovenia

Slovenians, who leave abroad for several generations and do not have documented pedigree, can still find their relatives and prove common ancestry by DNA testing.

Easter, the biggest Christian feast, by tradition brings families together. Long lost children return back home alone, or with their own families from capitals and foreign countries, to visit their parents along with other relatives, who never dared to leave the homeland. A week before and after Easter, roads become extremely busy. As reminders of peoples’ migrations, which were occurring over the Slovenian geo-strategic position also in the history: from North to South, from East to West. These patterns are still recorded in our genes. They are shown out in DNA analysis results and matching.

A celebration of spring starts at the beginning of Holy Week when bunches of spring greenery are brought to churches for the blessing. They differ in forms, size and species of greenery, flowers, and ornamentals, as well as by their names in different parts of Slovenia. The Christian custom of plaiting bundles dates to the 9th century and probably derives from a custom known throughout pagan medieval Europe. Easter has in Slovenia many colourful traditions and customs dating centuries into the past. Due to lack of food during the winter time, it was practical to introduce a long fast, which started on Ash Wednesday and ended on Easter Friday. On Easter Saturday a cooked ham, horseradish, potica, and pirhi are blessed in churches, to be later put on the table on Sunday morning.  A special Slovenian cake, potica, is still made at homes in Slovenia. Also colourful decorated eggs, in Slovenia called pirhi, pisanice, pisanke, remenice or remenke, make the feast special.

Slovenians, who can come for the Easter visit, are settled in other EU countries, as well as in Switzerland and Balkan countries. The largest part of the Slovenian diaspora lives in Germany, Sweden, France,  Austria, and Switzerland. The reasons for leaving home were of an economic nature. Similarly, emigration occurred in republics of the former Yugoslavia. Slovenians live in Croatia, Bosnia and Herzegovina, Serbia, Montenegro and Macedonia. 

Primarily for the economic reasons, the first compatriots left the homeland already in the last quarter of the 19th century, followed by departures in the 1930s, after World War II, and then in the 1950s and 1960s. Significant communities of Slovenian emigration is located in countries across the oceans in the USA, Canada, Argentina and other countries of Latin America, and Australia. Today, in these countries, we already meet with a third, and sometimes with the fourth generation of Slovenians. Many of them have been mixed with other nationalities, but for quite some, we can still find donors of DNA samples, which could be proved by documents to be of Slovenian origin.

Exactly for those we need to devote the most efforts that older generations are not the last Slovenians abroad. Slovenian Genealogy Society supports in organised and professional manner realisation of wishes of new generations to discover their roots and explore places of origin of their ancestors. In successful stories, Slovenes in the motherland and Slovenes around the world find their connections and become increasingly linked to Slovenia by the bond with the motherland, Slovenian language and culture.

Join the ‘Slovenian origin‘ group at FT-DNA. You can ask questions or publish news in the activity feed of the group. The administrators will help you with further information.

Family Finder can find your realtives

Bennett Greenspan is a pioneer in genetic genealogy. He founded the first American company to offer genealogical DNA testing directly to the general public in 2008. He is still in charge of this company as president & CEO and an enthusiastic genealogist, who manages also several projects and give lectures on the use of genetics in genealogy.

We speak about Family Tree DNA company, which developed first mitochondrial DNA and Y chromosome tests. In 2010 they launched revolutionary Family Finder test, in which they test and compare 700,000 letters in DNA. While testing of mtDNA and Y-DNA results enable discovery of deep ancestry of direct maternal and respectively direct paternal line, testing of autosomal DNA can give matches up to 6 generations back from the donor (last 150-200 years) with great accuracy.

When to take a Family Finder test? In case you are curious to know your ethnic, ancestral origin, and relatives you have never thought to find. This test is designed to find relatives on donor’s ancestral lines within the last five generations by any male or female line. At the same time, Family Finder gives you a breakdown of your ethnic makeup by percent (myOrigins) by comparing your DNA to reference populations around the world that have been tested through scientific research, especially archaeological, going back in time for last 50,000 years. Once your test is ordered and paid, no other costs are charged for running a profile with matching results (see some help, how to find your matches)

In choosing a donor it is very important to find the oldest living ancestor and ask him/her to give a biological sample. He/she is much closer to a genetic and geographic origin of source population than people born from a third or fourth generation in America due to combining of DNA and increasing number of ancestors at each passing generation.

Nowadays we have a lot of online records to search for genealogy. But the most important new tools available only since 2008 can help you find your ancestors even though you do not have written records about them. DNA testing can help you make the first steps in your journey ‘Trough your DNA testing to your Slovenian roots’. Or to any other ethnicity, of course. If you have already tested your atDNA and have Slovenian ancestry, join our group at Family Tree DNA ‘Slovenian origin‘.


Slovenian Historic Records in Latin and Old German

Despite Slovenians got their state already after the First World War (1918) in the Kingdom of Slovenes, Croats and Serbs, Slovenia was not independent state until 1991, after her split from Yugoslavia. As Vatican was one of the first states that internationally recognized the newly created independent state of Slovenia in 1992, Slovenians will forever remember the Pope’s words in Slovenian at the occasion of his visit in 1996: “Papež ‘ma vas rad!” (“The pope loves you!”). Pope’s John Paul II visit was devoted to celebration of the gained independence of the Slovenian state and to commemorate the 1250th anniversary of Christianity among the Slovenians.

In 8th Century Slovene people start loosing their independance first under Franks, then under the German Holly Roman Empire. This influenced also the culture, including the langugae use. The Freising Manuscripts are known as the earliest document of Slovenian culture, created in 10th Century. These prayers are the earliest preserved writings in Slovenian, as well as the earliest Slavic texts, written in the Latin alphabet. ‘Monumenta Frisingensia‘ (can be listen and read online in translation from early Slovenian into five languages, including modern Slovenian) have documented the use of Slovenian langugae in Christian liturgy in Upper Carinthia, which belonged to the Freising diocese. Later the liturgy was hold everywhere in Latin as this was the official European langugae.

This means that general public still spoke Slovenian langugae, but official languge of nobles and the rulers became first Latin and from 12th century the German. Dictionarium quatuor linguarum is a 16th-century book by the German polymath Hieronymus Megiser that includes a multilingual dictionary with German, Latin, Slovenian and Italian vocabulary. While a large part of Europe in the 16th century adopted a humanistic cursive (“Latin” script, antiqua) as the dominant font, the duality between the “German” and “Latin” fonts was maintained in Central Europe until the begining of 20th century. So the archive documents could be found in Latin and German also for Slovenian origin. While the Latin records are easy to read, a German handwriting is more demanding and requires skilled genealogyst or translator. In both cases basic vocabulary needs to be learnt to understand written information, for example an occupation.

Despite all these historic records in German, and information at the imigration documents, that passanger’s state of origin was Austria, your ancestor may be of Slovenian origin. If you start discovering this by your genetic matches in Slovenia, do not hesitate to contact them – in every family you will find somebody, who speaks English.

Many Americans imagine Slovenia as an eastern communistic country, close to Russia. Which is far from truth. Firstly, Slovenia has a Central European geographical position, and secondly, her communistic party split from Russian policy soon after Second World War. As Slovenia was one of the six Yugoslav republics, certain level of self-governement was retained. For example, Slovenia got her first constitution in 1947. Nowadays we can read legislation and use Slovenian langugae in all official procedures not only in the Republic of Slovenia, but also in the institutions of the European Union. Whether this is a guarantee that a language spoken by 2 million of people will survive in globalised world or not, we can not say.

What is worth mentioning, the Slovenian origin means ethnicities rooted in the geographic regions in Central Europe, where Slovenian speaking people have lived in the past millennium and have been using various Slovenian dialects (Ramovš, 1931).

Classic vs. genetic genealogy

Since 2000 genetic genealogy is available for commercial use, as the DNA testing became available. Since then, consumer genomics testing has been increasing exponentially, especially for genealogy purposes (can be ordered also for health, nutrition, etc.).  With the help of advanced techniques and information technology, for a consumer, a biological evidence is easier to compare than historical records.  Matching of potential relatives simply occurs on your screen. Of course, the investigation only starts with this and has to be done in combination with data from traditional genealogical and historical records. For the Anglo-Saxon world, great databases of genealogical and historical records have been available online, so your research can be done from anywhere anytime.  Also in our country, you can find great sources of historical information online, like in Digital Library of Slovenia, or the register of cultural heritage (a register of protected cultural monuments, including archaeological sites, secular and church buildings). But, what about the genealogy sources?

In Slovenia, the primary sources of genealogical information can be obtained from the civil and ecclesiastical archives (Ljubljana, Maribor, Koper), where these are largely still available in the form of original books or their duplicates, created more than 100 years ago. Younger books are still in use by official registrars at administrative units. Because of data privacy rules, an access to these registers at administrative units is very limited: you need to be an immediate relative or registered researcher with an authorization of a descendant to be able to obtain genealogy relevant information even for events 100 years ago.

The main registers, used for genealogical research are birth, death and marriage books, for which responsible registrars or priests enrolled the life events of the residents of a parish to which they belonged in a given period. Thus, it is necessary to know for each person a period in a history, the relevant administrative  or church territorial and hierarchical organization in the Habsburg Monarchy, to locate the register in the correct archive, parish and book. While the church records of settlements which remained in Austria until today are online, for settlements, which are today in Slovenia, this is not the case. Not even half of parish books have been scanned, but also the scanned ones are available via a very limited number of client screens, placed in the archives. A long waiting period, short working hours and long summer holidays make a lot of opportunities for dissatisfaction with the situation.

We would need the wisdom and openness of the enlightened ruler Maria Theresa, who introduced numerous reforms in 18th Century in these countries, still nowadays. Her military surveys have been revitalised by digitalisation and georeferencing in the MAPIRE portal, that serves today online to interested users. Old maps of cities and countries can be viewed in a synchronised and even 3-D view.

But, again in a case of cadastral maps, these are available for neighbouring countries of former Austria-Hungarian Empire. For Slovenia, only Krain/Carniola region is included. As the state archive has no interest to participate in a project. Maybe the Ministry has recognised the financial interest of a private company behind a user-friendly searching of historical places: first, they offer their services free of charge, to attract users and donors of material, then they start limiting the access and charging for their upgrades. However, Slovenia offers the Francis cadaster (SVN Franciscejski kataster, GER Franziszeische Kataser; Franz II, Holy Roman Emperor) of parcels of land and their owners and users for a period 1818-1828 online (zoom-in). 

Franciscejski kataster today

Good news is, that the Archive of the Republic of Slovenia offers also all cadastral maps and scanned registrars at their portal free of charge for low-resolution maps (high resolution can be ordered). These are in a bit rigid archivist form, which demands some knowledge of past territorial organisation. We share this knowledge below to enable their usage for Slovenian land (alphabetical lists of owners and other lists, which enable restoring the farms, are freely available). Nowadays statistical regions are indicated above the historical Habsburg regions for a given period:

Three examples on the picture give a basis for the surname explanation:

  • Hostar, the surname still exists today in a form of Hosta (etymology: by field name ‘na Hosty’ = in the forest)
  • Lebek, the surname is extinct (etymology: by field name ‘na Lebeki’)
  • Farbar, the surname is extinct, or it exists in a form of Brvar (etymology: the owner of the farm had also an occupation being a painter = ‘barvar’, from ger. Faerber, Färbar)

Autosomal DNA testing for genealogy has become popular and affordable. In some cases, it is a substitute for classic genealogy research in archives and libraries. Luckily, with the matching of specific codes of the autosomal DNA, there is a possibility of finding a cousin when both submit their biological sample for testing and make their results available for consultation. In 2018, the atDNA results for the purpose of ancestry testing can be obtained for less than $100 from some reliable providers (Family Finder test at FamilyTree DNA, MyHeritage DNA, Genographic test at National Geographics, Ancestry DNA, etc.). Testing of atDNA can be upgraded by testing of Y chromosome, X chromosome and mitochondrial DNA at FamilyTreeDNA, to get deep ancestry information for thousands of years ago and more precise affiliation to ancient tribes. Wast legacy kept in each human genome can be revealed. This is a good investment for the future and great opportunity to preserve our eldest relatives, parents, grandparents alive by their biological sample containing DNA information also after they pass away.

A basic question of this project is: Could we collect genetic genealogy results of Slovenians and Americans of Slovenian ancestry into a joint database and set standards for certain origin of Slovenian population? We decided to address this question to people, interested in Slovenian origin and their own pedigree (see the survey).

Before the World War I and during it, many Slovenians left their country for a better life. In the last decades before the WWI, it is estimated that the process involved up to 300,000 people. The emigrant wave was directed mainly to the United States, partly in German parts of Austria, Germany and Egypt, only to a lesser extent to South America (Brazil, Argentina). As emigrant and immigrant statistical records managed the expatriates by country of origin, to which Slovenians belonged in that time (such as Austrians, Hungarians, Italians, etc.) it is very difficult to find people. Many of them travelled by railway through Ljubljana to European ports as Trieste, Rijeka, Genoa and Western European ports, e.g. Cherbourg, Le Havre, Antwerp, Rotterdam, Bremen / Bremerhaven, Hamburg and other ports, e.g. Southampton in England (M. Drnovšek).


Port of Trieste was a starting point of many Slovenian emigrants. In 1910, there were 60,000 Slovenian inhabitants in Trieste and twice as much of Italians. Today Trieste belongs to Italy.

By passing four to six generations since emigration, many contacts between emigrants and their relatives in Slovenia have been lost during the last century. In the era of early 21st Century, we have the last chance to reveal our ancestral origin to founding populations from just a simple saliva or cheek tissue sample. From this sample, a unique DNA pattern can be determined, which can link individual Americans of Slovenian ancestry to their origins in the territory of Slovenian speaking people, before all information is melted in a contemporary mixing of populations and natural dissolving of inherited DNA through generations.

So, in our project ‘Slovenian DNA Pool’ all interested participants from both sides of the Atlantic Ocean are invited to provide their GEDMatch number along with their real names and surnames and e-mail for the collection of Slovenian DNA Pool, as well as to share their DNA and genealogy data. Managers and administrators of the project will carefully consider the data before publishing. If an alias were provided, it would be displayed in place of the real name along with DNA results.

Collected information will be used for research purposes only. Anonymised data could become part of a bigger database, as it is more and more often for crowd-sourced genealogy. Furthermore, each individual can benefit from the database to find their long lost relatives and upgrade genetic ancestry by family tree.
