dnaGenetic testing for genealogy has become more available, affordable and popular. But what do the results from such tests really mean? Mr. Jim Logan will help make sense of the science behind our family history.

After a brief introduction of DNA and its place in biology, three different types of DNA tests will be discussed with demonstrations of how Y-DNA tests results have successfully been used in genealogical research to identify relationships between families and thus extend genealogical knowledge beyond the written record. Similarly, autosomal DNA results will be presented to show how they can be used to find cousins who in turn can share results and extend trees into branches where research is the most difficult. Finally, test companies will be identified and differentiated, showing pro and con of each.

Mr. Logan, as Administrator of the Logan DNA Project, analyzed and identified genetic relationship between families represented by tests. Based on these relationships, many of family profiles have been grouped, facilitating more concentrated genealogical research. In 2005, Jim organized and still manages a Special Interest Group on Genetic Genealogy for the Fairfax Genealogical Society. This group generally meets once per month during the school year for lively discussion on all things to do with Genetic Genealogy.

Join us for “Understanding Genetic Genealogy” with Mr. J. J. (Jim) Logan on December 3, 2013 at 1:45 p.m. at the Bon Air Presbyterian Church, 9201 West Huguenot Road, Richmond, Virginia.
