Re: FTDNA Sephardic Results Question #dna

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
