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 od 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.
