    Question GEDmatch - Weird results, but do they mean something?

    My known background is about 97% British and Irish (~30% Irish, mostly from County Mayo, and ~67% English, mostly from London and Liverpool). The other 3% is likely Portuguese: 23andme identified me as 2.3% Spanish and Portuguese, 0.2% Broadly South European and 0.2% Unassigned.

    However, when I uploaded to GEDmatch my results seemed really strange. There was a lot of Finnish and some Russian in the results. I did some digging and worked out it was because every result had identified me as being 2-3% Siberian, Ural-Volga or from locations in North West Asia. I checked the population averages and my other percentages seem consistent with being British, but the British average for Siberian is 0.

    I have no known ancestry from this region at all, although GEDmatch gives me a few matches with Russian and Swedish names and 23andme linked me with 2 Finns and a lady from Belarus. There were no matches from Spain and Portugal, although a few people with the surname ‘Silva’ popped up on GEDmatch.

    So what does this mean? Is it real? Has it misidentified some British, Irish or Portuguese? Is it normal for Irish Londoners? It would be cool to discover some unknown Russian ancestor, but my AncestryDNA and 23andme results said nothing about this location so I remain sceptical. Is it possible it’s just wrong? FTDNA gave me 3% Finnish and 7% West Slavic, but I dismissed it because there’s no way this can be correct.

    Iíve checked out the matches from Finland and Belarus etc. Itís interesting because some of them have Southern Europe in their results.

    I wonder if we may be connected through Greece or Italy somewhere. It doesnít explain the Siberian, but it explains the matches. Maybe GEDmatch is wrong?

    I was put straight onto 5.9 so I can’t check my results. However, I saw them briefly when comparing my ethnicities with others. Apart from British I think it said ~5% French/German, 0.7% Scandinavian, 0.5% Broadly Southern European, 0.2% North African.

    Interesting, what are your full AncestryDNA results?

    These siberian and volga-ural scores definitely point out to northeastern euro ancestor imo

    I am half Russian (northern and finno-ugric shifted) and this is my relevant k36 components:
    Eastern_Euro 9.37 Pct
    Fennoscandian 8.22 Pct

    Siberian 3.97 Pct
    Volga-Ural 1.69 Pct

    Even my Volga-Ural is less than yours (and i have grandparent from Volga region) and my Siberian score could also be contributed from my Central Asian side (east eurasian admixture).

    I have 4% Volga-Ural, if it is all from my great grandmother, than she had 32%, is this amount normal for Uralic Russians?

    I suppose yes, if they have local admixture. For example, i have seen Chuvash score 100% Volga Ural. For Western Russians this component should be lower.

    Is this component Slavic, Finno-Ugric, Turkic or mixed Slavo-Turkic? if I am not wrong Chuvash people are Slavo-Turkic genetically
