Analysis of information sources in references of the Wikipedia article "Genetic genealogy" in English language version.
The growth of interest in genetic genealogy has inspired a group of individuals outside the academic area who are passionate about the subject and who have an impressive grasp of the research issues. Two focal points for this group are the International Society of Genetic Genealogy and the Journal of Genetic Genealogy. The ISOGG is a non-profit, non-commercial organization that provides resources and maintains one of the most up-to-date, if not completely academically verified, phylogenetic trees of Y chromosome haplogroups.
Years of researching his family tree through records and documents revealed roots in Argentina, but he ran out of leads looking for his maternal great-grandfather. After hearing about new genetic testing at the University of Arizona, he persuaded a scientist there to test DNA samples from a known cousin in California and a suspected distant cousin in Buenos Aires. It was a match. But the real find was the idea for Family Tree DNA, which the former film salesman launched in early 2000 to provide the same kind of service for others searching for their ancestors.
A real estate developer and entrepreneur, Greenspan has been interested in genealogy since his preteen days.

Greenspan, born and raised in Omaha, Nebraska, has been interested in genealogy from a very young age; he drew his first family tree at age 11.
The [DNA] test results show a genetic link between the Jefferson and Hemings descendants: A man with the Jefferson Y chromosome fathered Eston Hemings (born 1808). While there were other adult males with the Jefferson Y chromosome living in Virginia at that time, most historians now believe that the documentary and genetic evidence, considered together, strongly support the conclusion that [Thomas] Jefferson was the father of Sally Hemings's children.
