    If they're a more complex mix, rather than a straightforward case of one European and one Near Eastern parent, it is trickier.
    Half Lebanese Christian and half north Italian,the results are compatible?

    [1] "distance%=3.1344"

    Person_scaled

    Lebanese_Christian,53.2
    Italian_Liguria,46.8


    I guessing based on something like this:

    [1] "distance%=2.1862"

    Person_scaled

    Syrian,56
    Italian_Liguria,28.4
    Italian_Lombardy,15.6


    Of course these are closely related and overlapping groups, so you can't distinguish them reliably in G25.

    So it’s compatible to half Lebanese Christian and half North Italian admix ?

    Compatible? yes, however not optimal. The Lebanese half of the equation is probably a bit diverged from the Lebanese Christian average.

    If we subtract the Lebanese Christian average from the "Unknown" sample, and then run a model, the European groups with the closest fits required to recreate the other 50% of Unknown are:

    Sample Distance
    Spanish Galicia 5.9162
    Italian Tuscany 6.2277
    Italian Liguria 6.3204
    Roma Bilbao 6.3327
    Spanish Girona 6.4496
    French Provence 6.4593
    Spanish Alacant 6.5202
    Portuguese 6.5242
    Spanish Canarias 6.5665
    Roma Granada 6.577


    Note the high-ish distances.

    Here is the same exercise in reverse - Subtracting Italian Tuscany from Unknown

    Sample Distance
    Syrian 5.0688
    Jordanian 5.2009
    Karaite Egypt 5.6864
    Lebanese Muslim 5.7224
    Palestinian 5.8038
    Lebanese Druze 6.0699
    BedouinA 6.2203
    Druze 6.4373
    Iranian Jew 6.5798
    Samaritan 6.5937
    Iraqi Jew 6.6521
    Georgian Jew 6.7917
    Lebanese Christian 6.8019
    Syrian Jew 6.8252
    Romaniote Jew 6.8588
    Assyrian 6.9346
    Libyan Jew 7.0842
    Mountain Jew Chechnya 7.3021
    Sephardic Jew 7.3091
    Iranian Fars 7.3128

    Definitely - individual people vary a lot from Global25 population averages, and there is always some noise and slop in the process. G25 can't tell if someone is recently mixed, either - we have only your information to tell us that.

    A commercial test that does chromosome painting might be better for this, since you could match chunks of DNA inherited from each parent with other people.

    What group in middle it’s more compatible so? Lebanese Muslim? Because his dad is from a historical muslim village who many convert to Christianity a long the time

    Yes, his father is probably closer to the Syrian and Lebanese Muslim averages than the Lebanese Christian average. Do keep in mind that we're talking purely in terms of averages. There is a lot of overlap among these groups and chances are that his results would be within range for Lebanese Christians as well.

    And if take half north Italian because his background is half north Italian and sometimes fit around Spanish sides
