    I had to imagine more Ashkenazi admix.

    I'm not an expert on this but aren't ashkenazis highly mixed anyway? In the sense that aren't they basically a three way mix of 'East Central Euro', 'Italian' and 'Cypriot/Levant/ENF'? If that is the case, how is anyone going to ever be able to determine their specific Ashkenazi admix? let's say you wanted to determine how much Bedouin ancestry you have, this would be easy as the Bediouns have a component that is pretty much all there's or that peaks in them (Red Sea), you could also easily tell how much Samaritan ancestry you had (East Med component), whereas with a people who are a rough blend of multiple and different components - is determining specific Ashkenazi admix - especially when your ancestry is from groups with similar components to the ashkenazi - is this going to be doable?

    I can imagine it would be easy if you were lets say mixed Chinese and Ashkenazi, whereas if you are mixed Sephardi/uzbeki jewish how can you determine which of the component scores come from your ashkenazi admix and which don't?

    Genuine question - not a rhetorical point.

    DNA land highly underestimates Northwest African/Berber related ancestry in non-Northwest Africans. You should use gedmatch.com instead and you might also be able to get an answer from Dr McDonald if you mention your "rare" ancestry in the title of your e-mail.

    I think that component is hidden in Arab/Egyptian but I'm yet to see any berber dna land results.

    Who is Dr Macdonald? And how would I get hold of him?

    He's a university professor who has an interest in population genetics, he used to run his own analysis project but he doesn't seem to respond to people except those who he finds exotic or rare (so you may have a chance). I'd recommend you send an email with a vague description of your ethnic background, a request for a plot/analysis and your 23andme raw data. His email address is: jdmcdona@illinois.edu

    Have a look at this thread for some example results from users here:

    Also I would recommend interpretome to look at some PCA plots and where you'd fit on them

    It's amazing the difference in the analysis from one to the next. My DNA.Land results show 49% Eastern European/Northern Slavic (Belorussian, Estonian, Lithuanian, Russian and Ukranian) which is correct on my maternal side. It's showing 29% North Central European (Scottish Argyll, Bute, England, Icelandic in Iceland, Norwegian in Norway and Orcadian) as positive matches. It also shows 21% Italian which I never seen before until now (Italian Bergamo, & Italian Tuscany for a few). Another 1.2% Ambig (Egypt and Levantine Israel).

    If there are Italian matches then they must be from my maternal side because I don't see any Italian ancestry on my paternal side that would give a 21% return? Given the high percentage of Eastern European from my mothers side I'm guessing this only goes back 5-7 generations in terms of a profile?

    DNA Land is overestimating Balkan for many people. Myself included. They are supposed to be working on this issue.
