    Significantly higher Iberian than Italian on Gedmatch than on Ancestry

    i score 36% Italian/Greek and 0% Iberian with AncestryDNA yet with Gedmatch I seem to come up with almost twice as much Iberian than Italian?
    Anyone else of Italian decent having similar results when comparing Gedmatch to there AncestryDNA results in this department?

    Looks like you are northern-italian (which region ?). Well, some northern-italians are genetically close to iberians, seems normal. On AncestryDNA the iberian component is more basque-related, that's why it doesn't appear in italians. But spaniards do get some of the italy/greece component.

    True that some northern Italians are genetically close to Iberians, especially northern-western Italians, but it's quite obvious that he is mixed, in some calculators he comes up as French. He claimed to be half Italian (more like a central-southern rather than a central one), half British with minor Jewish ancestry in his British side.

    Replying to both Sweuro and Pratt above.
    Thanks again for taking the time to check my data and voice your opinions.
    It's appreciated.
    I am indeed only half Italian.
    Father from Lanuvio in Lazio region 20km outside Rome.
    Mother from Essex in England and before that East London from a predominantly British family with a Jewish great great grandfather.
    Genetically she is only 22%British and a further 53%West European 10%European Jewish 8%Iberian..etc..
    I imagine like 'sweuro' says that much of the Spanish content is probably a typical component that factors in amongst Italians when measuring for the Italian/Greek ethnicity on AncestryDNA. Also 'Pratt' it would seem that my mothers 10% European Jewish is in fact of the "Sephardi Jewish" variety originating from Spain lol and I guess this would account for her 8% iberian in her ancestry results which in turn by me inheriting 6% of her Sephardi Jewish would probably influence my Iberian percentages somewhat on Gedmatch if not AncestryDNA.

    I can confirm that North Italians sometime show up Spanish. Happens for me most of the times.

    I think Nino wants my kit to be analyzed.Just a little background. My mother is 100% British/Irish or close to it, and I grew up knowing only her family. My father was, supposedly, either fully or half Italian. I tested with 23and me and my results came back 0% Italian. They actually show 0% Southern European. I'm not sure I can post links or images yet, but will do so, if it's possible.
