FTDNA Sephardic Results Question #dna
Beth Long
Hi Ben,
from a 62-person spreadheet I have >from my Hungarian Bukovina project,using the "old" algorithm, there were 8 people showing some level of Ashkenazi Diaspora (AD). Of these, three now show zero according to the new system. I should add that none of them has any known Jewish ancestors within the last six generations at least. Of the remaining five, one went >from 9% AD to 3% Ashkenazi and 12% Sephardi, one went >from 11% AD to 6% Ashkenazi, One went >from 6% AD to 3% Sephardi, one went >from 6% AD to 3% Ashkenazi, and the last went from 6% AD to trace levels of both Ashkenazi and Sephardi.In addition to those eight, there are an additional eight people who showed zero AD under the old algorithm, but now have either 3% or 5% Sephardi. Likewise, no known Jewish ancestors. This is an unusual group, who are thought to be the nearest genetically to the Magyar tribes who came to the Carpathian Basin in the late 9th century. There are notable elements of Siberian, east Asian, Asia Minor, Caucasus, and steppe Turkic tribes in the population. I should add that two of the individuals are a brother-sister pair. In the first round, the brother had zero AD, and the sister had 6%. Now the brother shows 5% Sephardi, and the sister has traces (under 2% each) of Sephardi and Ashkenazi.

Hi Genners
Following the update of the FTDNA MyOrigins tool I re-analysed my Paternal Family's results and found that one of my dad's cousins (1st cousin once removed) came out as 8% Sephardic, this didn't entirely surprise me since she had the highest amount of South and Eastern Mediterranean under the old results. I have my dad, his brother and 3 cousins in FTDNA and the same plus more in GedMatch (transferred from 23andMe) I've previously run all of the family through the Admixture tool and have received reasonably similar results for each, so I was wondering: - Does anyone know on what basis the new MyOrigins tool recognises Sephardic DNA and who the reference populations are - Is there a way of using the GedMatch admixture tests tools to try and isolate the most likely population >from which this ancestor came. Accepting that it's more likely to come >from an ancestor of my dad's cousin rather than any shared ancestor Thanks as always Ben Ben Forman Searching: BENSON: Hasenpoth/Courland; BERNSTEIN/WEINER: Ylakiai; CAHN/CAHEN/WOLF:Zuendorf/Bruhl/Lechenich/Ahrweiler; FURMAN: Kaluszyn; GEVER: Daugavpils/Dvinsk; STILLMAN:Pilica/Ogrodzienec SAWADY: Zavadi,Posen;
