My mother also has a little Italian and a trace amount of east-european in her estimate. I thought maybe the eastern-european indicates a little Ashkenazi, but the myheritage specialist I spoke to on the phone told me he leans more towards the assumption that my mother is of Sephardic descend because he, also a sephardic Jew, also has traces of east-europe and italian, but has no eastern-european nor italian ancestors. I find that a little hard to believe though, or I didn't get him correctly (the connection wasn't that wonderful either). I think I'm gonna place my bet on the "sephardic man that married an ashkenazi girl in the 1800's before his descendand got sent to Suriname" theory
    Your explanation seems more reasonable, but based on the Eastern Euro admixture, not the Italian.
    I would expect both Sephardic and AJ to score Italian, Ashkenazim spent considerable time in Roman-era Italy before crossing the Alps and mediterranean ancestry is hard to disentangle, resulting in Sephardic Iberian ancestry being picked up as Italian. It's more reasonable to assume that only the Eastern Euro is specific to AJ.

    I can't think of a reason why they should. Most of their non European and non-Levantine origin is derived from Berbers.
    Never worked with myheritage or Sephardics though. Please don't assume on my J-M92 I have any elevated knowledge on these topics.

    Do you know any living male descendants of your da Mesquita forefather?
    A genealogist could result in nothing, while the Y-haplogroup always answers at least some questions of your unknown ancestry.

    No, unfortunetaly. I know someone named de Mesquita that may be related in some way. Or I can ask someone else with that name (guess they're easy to find these days whit all the social media websites). But thats a little too much I think. Approaching strangers saying "Hey, we're probably related! Help me out?".

    I asked if Sephardim score East-African because almost every Sephardim kit I ran the Jtest or EUtest on shows like 3 to 5% East-Africa. My mother also has a little East-African

    Another option is to rely on public results, like searching familytreedna projects.
    There's one that lists a "Mesquita" from Portugal as R-SRY2627.
    https://www.familytreedna.com/public...ction=yresults

    The easiest thing to google is this:
    site:familytreedna surname

    If ftdna provides the full name, place of residence or the dates of birth and death, sometimes it is possible to fit them into a genealogical tree of yours.
    Otherwise these results are connected to the huge uncertainty of multiple-origin surnames or non-paternity events and therefore more or less useless.

    My full Sephardic matches also seem to have a few pages full of Ashkenazi matches on FTDNA. I think it might be similar genetics - these full Ashkenazi matches are usually always 4+ generations back.

    Indeed. I ran the Jtest on several matching kits with that tunisian jewish kit and seen alot of Jewish matches get score more then 30 on the Jtest

    I'm half Ashkenazi/half Sephardic but I only score 18 on the Jtest. Although the population group they give me usually is 50% Ashkenazi and 50% Sephardi, so that's perfectly correct.

    Where can i see the score on Jtest, or do you mean the ashkenazi percentage?

    Yes? I don't understand your question? When you run the Jtest on a kit-nr you'll get a percentage for the ASHKENAZI score. Above 24% usually means 100% Ashkenazi Jewish

This made me conclude there must have been an Ashkenazi Jewish ancestor in our family tree. Some persons told me thats not necessarily the case and that Sephardic Jews share DNA segments with the Ashkenazim. That I understand, ofcourse. They both descend of the same people from the Middle-East, but this is like 2000 years ago. How is it possible to genetically match this strong with people while the shared ancestors are from more then 1000 years back? Can this really make you match to more then 90 Ashkenazi Jews?

    Another question; Is there someone with or who knows someone with a sephardic Jewish kit @ Gedmatch that doesn't have any Ashkenazi ancestors? I would like to see if other Sephardic Jews match to this many Ashkenazim also.
    Atzmon found that it was difficult to separate modern Sephardim from modern Ashkenazi. Syrian Jews were also close.
