In this post you will find the rest of the email by Crispin Rendon. It is in regards to Jewish roots. Crispin has undertaken the issue that his DNA as well as many others has been labeled Ashkenazi when it is well known that the Jewish roots for our area are Sephardic. Hopefully in the future FTDNA will differentiate these two better, but more work and research has to be done.
The Rest of the Email by Crispin Rendon
Many years ago I learned of some research by Jose Antonio Esquibel connecting him and therefore our kindred group (with roots from the Mexican States of Coahuila, Nuevo Leon and Tamaulipas) to Men Gutierrez and Isaac Ha Levi both Sephardic Jews.
You can learn more about Men Gutierrez at this website:
A few years ago I had my autosomal DNA tested at FamilyTreeDNA with a test they call FamilyFinder. Two years ago my test results changed to showing 10% Jewish Diaspora, Ashkenazi. Actually the raw data test results did not change but the algorithm that creates the interpretation that we think of as results changed (see my test results below). I hope they change again soon with my Ashkenazi DNA reclassified as Sephardic DNA. We can leave that for another time.
There is a well known oral tradition that our ancestors from Monterrey had Jewish roots so how much Jewish DNA do we as a kindred group have? That is the question I hope to address by using our kindred group genealogy database. I surveyed 132 cousins from the kindred group database that have FamilyFinder test results, asking that they log on to FamilyTreeDNA and report on how much if any Jewish Diaspora DNA they showed. Counting myself, we have 60 responding to the survey.
This is a summary of my relationships to the survey responders: 1-4th cousin, 4-5th cousins, 11-6th cousins, 30-7th cousins, 10-8th cousins, 1-9th cousin, 1-10th and 1-11th cousin.
This is a summary of reported percentage of Ashkenazi DNA:
49-Zero percent, 1-5%, 4-6%, 2-7%, 1-9%, 1-10%, 2-13%
Genetic Testing Survey Conclusion:
18% of our kindred group report some Jewish Diaspora results from FamilyFinder testing. The test results range from Zero to 13% Jewish Diaspora.
I checked our database of over 362,000 records to see if the same 60 people descend from Men Gutierrez and or Isaac Ha Levi. I also checked to see how many ways we descend from them.
Number of ways we descend from Men Gutierrez: 11 people not descendant, 10 people 1 way descendant, 18 people 2 way descendant, 4 people 3 way descendant, 3 people 5 way descendant, 3 people 6 way descendant, 2 people 7 way descendant, 2 people 8 way descendant, 4 people 9 way descendant, 2 people 10 way descendant and 1 person 11 way descendant.
Number of ways we descend from Isaac Ha Levi: 31 people not descendant, 11 people 1 way descendant, 8 people 2 way descendant, 3 people 3 way descendant, 2 people 4 way descendant, 1 person 5 way descendant, 1 person 6 way descendant, 2 people 8 way descendant and 1 person 12 way descendant.
I hope that you have found this topic to be of interest to you. Please let me know your opinion or comments about this subject in the comment section of this post. Let me know if your results have also been labeled as Ashkenazi but you believe that they should be Sephardic. You can also help Crispin with his research by sending him your DNA results showing Jewish Ancestry along with your family tree.
