Judaism is a religion and not an attribute definable by a DNA mutation, but we can give you hints about having Jewish ancestry by comparing your Family Finder results to those of known Jewish ancestry in our database. myOrigins results may also provide clues to recent Jewish ancestry in the last five generations.
The first clue to your having recent European Jewish ancestry is the number of matches you have in the Family Finder database. Due to endogamous marriage patterns, there is a high level of inter-relatedness in European Jews. If you have recent Jewish ancestry, you will then have a high number of Jewish cousins on your matches page, likely in the 1000s of matches.
The second clue to your having recent Jewish Ancestry comes from the myOrigins ethnic percentages results. Most people with Jewish genetic ancestry will see Ashkenazi or Sephardic Jewish ancestry here. However, if you show only a small amount of Jewish genetic matching, it is not proof of recent Jewish ancestry. This is because the genetic match may be from much more distant genetic admixture that became fixed in your recent ancestors’ population. Please note that we are only able to assist with Ashkenazi and Sephardic Jewish ancestry at this time.
