"Can You Help Me Find My Cousins? Understanding Autosomal DNA"
presented byMary Kathryn Kozy, President of JGSWS


DNA testing has really come to the fore as a way of helping us break through brick walls and challenges in our genealogical research. Family Tree DNA has one of the largest DNA databases in the world, particularly for Jewish researchers. But other DNA testing companies are now jumping into the mix. In addition to Family Tree DNA’s “FamilyFinder” test, Ancestry, 23andMe, and others also offer autosomal tests. How are these companies the same? How do they differ? What can autosomal DNA testing tell you and what are some techniques you can use to help you interpret the results? Come learn about what autosomal testing can and can’t do for you, some of the challenges with interpreting results in tightly knit communities like the Jewish community (or others, such as Colonial, Mennonite, pioneer, etc.), and what type of work it takes to interpret your results.
