Ashkenazi and Me – Discovering Unknown Jewish Ancestry with 23andMe
May 17, 2012
Finding Your Roots with Henry Louis Gates, Jr. begins its 10-week run on PBS, The Spittoon will feature posts from 23andMe’s Ancestry Ambassadors featuring their own stories about using DNA to dig into ancestry.By CeCe MooreI have always felt a special affinity for Jewish people and their heritage. Throughout my life I have had many Jewish friends.I have even been mistaken for a Jewish person despite having no known Jewish ancestors.As a result, I was especially intrigued when, after 23andMe’s Ancestry Finder launched in 2010, I found that a number of people with segments of DNA that matched mine were self-identified as Ashkenazi Jews. The Ancestry Finder lab seeks to graphically illustrate the country of origin for certain segments of your DNA by locating stretches that match those of people from specific geographic regions. Ancestry Finder also identifies matching segments for Ashkenazi Jewish ancestry. Relative Finder who list their ancestry as Jewish. Most of these are predicted as “Distant Cousins”, which probably explains why they don’t show up in my Relative Finder. In this case, testing just one generation further back in time revealed very useful information.While this Ashkenazi ancestry is fairly distant, it certainly appears to be authentic. With approximately 70% of my uncle’s chromosomes covered in Ancestry Finder, 3.6% – 7.8% is declared Ashkenazi. With this in mind, I would guess that he and my father have a 2nd great-grandparent of primarily Jewish descent or several ancestors with lesser amounts of Jewish ancestry. Jennie Cole’s father is unknown, this scenario is certainly a viable possibility. In order to focus in on this prospect, I would need to test more of Jennie’s descendants to isolate her DNA and determine if there is evidence of Jewish ancestry in the portions of the DNA that each of them inherited from Jennie. Since the paternity of Jennie has long been an enigma to me, this is a very intriguing new avenue of exploration for my genealogy research.Before testing at 23andMe, I never would have imagined that I had Jewish ancestry. Now that I have discovered this tantalizing fact, I am on the hunt to learn more about this elusive ancestor!23andMe provides genetic testing services for informational purposes; your results may or may not help you to search for or identify relatives or family members.
