  • How shall I interpret the results of myOrigins

    I am german born in Silesia (Poland). All parents come from the same region, except a ggg-grandfather who seemed to be jew and an other ggg-grandfather who come from North of Spain. FTDNA myOrigins tells me that I am 100 % european, 83% east european, 12% british isles and 5% finnish. How is this possible? Nobody in my family ever had finnish or british parents.
    There is 0% jewish Diaspora, 0% percent Spanish origin.
    I have to add that my gg-grandmother, with jewish origins, looked oriental and really not german at all. She was dark with olive skin. The spanish ggg-grandfather had a spanish name and spoke spanish or catalan.
    In Gedmatch I found 2,7% Ashkenazi with the Jtest and 2,2% Red Sea with Eurogenes 13. Gedmatch tells me also that I am not german but ukrainian with 6% West asian origin...
    What shall I think of all this?

    Finnish roots

    Hi Schokolade,

    I will also send you a pm in German.
    As far your small percentages of British Isles and Finland are concerned, you have to look at the Polish history, and European history in general. Think of the Vikings that attacked the European mainland several times, and of merchants. Prior to the Peace of Oliva (near Gdansk) in 1660, Swedish troops occupied parts of Poland and Denmark. And Sweden back then also included Finland:
    Some of the Swedish soldiers might have just stayed there, in Poland. I have the FN Markull in my family, which originated fromMarkkula - a very common name in Finland, like Müller in Germany. The suffix "a" was dropped after they had been living in Poland for several decades, probably because this suffix was reserved for female family members (Jankowski/Jankowska for example). This is my theory... but I don't know why the "a" wasn't dropped in a name like "Labudda". Perhaps because it was Kashubian.
    I hope this info will help you!

      In addition to the historical wanderings that have mixed the genes of almost every part of Europe, there are two points you should consider:

      First, because of the way chromosomes are inherited and the random nature of recombination, it is likely that you do not have equal portions of DNA from all of your ancestors. Some will be under-represented, others over-represented. The more distant the ancestor, the more his or her share of your genome is likely to vary from the expected fraction. There is a significant chance that you have no genes at all from some of your ancestors. Therefore, it is not surprising that results from MyOrigins do not reflect the proportions that you have established from your pedigree, even if MyOrigins accurately measured the "ethnic origins" of your DNA.

      Second, I don't think it is reasonable to assume that the "reference populations" stated or implied by the MyOrigins results (Finnish, Jewish Diaspora, East European, etc.) are actually "pure" or that they adequately represent any historical population. They are based on relatively small samples (necessarily) of modern people whose genealogies are almost certainly incompletely known. There is no way to know, from the information provided by MyOrigins, to what extent the reference populations line up with real populations that exist to day or that may have existed in the past. It is not even clear, to me at least, that the concept of a genetically homogeneous population of "Finns" or of any other European ethnic group has any historical validity. I think it is more likely that real populations in Europe have always been mixed and diverse, at least as far back as there are historical records. Worse, there does not seem to be a way to validate the reference populations. Therefore, I believe we have to expect a considerable amount of noise from any admixture algorithm, including MyOrigins, even to the extent that the results may actually be meaningless.

        Hi Schokolade,
        My E13 one poblation give eight possibilities before ukranian and greek.

        1 Serbian @ 3.646646
        2 Romanian @ 5.953301
        3 Bulgarian @ 8.323470
        4 Moldavian @ 8.929241
        5 Hungarian @ 11.196259
        6 Croatian @ 11.285543
        7 Austrian @ 14.897521
        8 East_German @ 16.580975
        9 Greek_Thessaly @ 17.352514
        10 Ukrainian_Lviv @ 18.565834

        And my oracle 4 again give 10 posibilities before assert with the reality (ukraine+ukraine+greek+intalian)

        1 Cyprian + Estonian_Polish + Southwest_French + Southwest_Russian @ 2.042243
        2 Belorussian + Cyprian + Southwest_French + Southwest_Russian @ 2.124222
        3 Ashkenazi + North_Italian + Ukrainian + Ukrainian @ 2.132701
        4 Estonian_Polish + Tuscan + Ukrainian + West_Sicilian @ 2.150551
        5 Croatian + Estonian_Polish + Greek_Thessaly + Tuscan @ 2.204222
        6 Ashkenazi + North_Italian + Southwest_Russian + Ukrainian @ 2.205981
        7 Estonian_Polish + North_Italian + South_Italian + Southwest_Russian @ 2.211579
        8 Estonian_Polish + North_Italian + South_Italian + Ukrainian @ 2.219201
        9 Cyprian + Southwest_French + Southwest_Russian + Southwest_Russian @ 2.235423
        10 East_Sicilian + North_Italian + Southwest_Russian + Ukrainian @ 2.264955

        As you can see, I'm with you. Saddly you know that I haven't yet answers, except: "unnecessarily" (only in this I'm not agree with Jhon MacCoy) small samples. May be you will find an answer from someone that put light this matter, and this matter is really very controversial, and with important consequences."Calculators fails" in not enough. We must not reduce it. Anyway, we are staying walking.
