    Vahaduo has only 10 samples. 5 are close to Peloponnesians and some of them even cluster with Albanians. Obviously the sample size is too small, but it seems Smyrnians got recent ancestry from the mainland.

    It aligns well with historical fact. Izmir grew from a tiny village to a massive cosmopolitan place in a very short time period. Most of the residents there had moved from the nearby North Aegean islands or mainland Greece proper. So we should expect them to lie in-between the two genetically, with maybe a few mostly Anatolian outliers that had moved there from some place in the east.

    Can you share the coordinates for any compiled regional greek population that you have made (like Kefalonians ) and not available in the "official" list ?
    Thanks
    Averages for different areas in Greece is a work in progress. I am hoping to share the averages when both the number of samples and the number of averages is great enough. However I can tell you the ones already in the K13 source list seem to be quite accurate, as most averages I've made tend to be similar to those in the end.

    Why k13 and not k15?
    What about g25?

    Can you model the following woman's coordinates with your WIP averages and any other Greek averages for which you don't have something similar ?
    I think I've mentioned her before and I may have even asked you again in the past but I'm not sure.
    Anyway...She is 25% Cretan (mostly from Sfakia but also from Chania) , 12.5% from Milos, 12.5% from somewhere in the Karaburun peninsula (Smyrni would work ? ) and the remaining 50% is unknown. That 50%, her father, is what I'm searching for.. His ancestry is completely unknown though.

    Thanks!

    Yseq confirms/predicts j-m241.

    Which SNP tests should I order?

    Hi there. Does anyone have information about a result from Arkadia, Greece under E-A18844? (A brief overview here)

    What's the significance of this clade? It just seems Balkan. Could have made it to Arkadia in any number of ways.

    The spread of A18844 in the Balkans is linked to the Mataruga tribe and related smaller clans. In fact, most of the results on yfull can be traced back to specific areas in Montenegro and they're part of a recent post-medieval spread. But the distance of the Greek result from the other ones may provide information about their location before their spread eastwards from Montenegro.

    My friend's terminal ? Ydna subclade I-Y51589 is now published.
    TMRCA at around 1700ybp with the Bulgarian Pomak.
    What is the "age by this line only" ?



    Anything else worth looking/searching for ?
    Maybe a future test with ftdna bigY to have him on their tree too but also having a clearer image on the low confidence STRs that he currently has ? Supposedly there are more samples (mostly Swedes ) under the upper level I-Y16808 subclade compared to Yfull's tree.

    I was playing around with some of the Late Antiquity Roman samples, and noticed that RMPR121 and RMPR36 cluster just north of the Mycenaean/Empuries samples. Much like the Mycenaeans, they can accurately be modeled as a mixture between the Minoan/Aegean EBA samples and Yamnaya Steppe Pastoralists. However, they have slightly more steppe ancestry which pulls them north.

    Target: ITA_Rome_Late_Antiquity:RMPR137
    Distance: 2.1681% / 0.02168087
    82.6 GRC_EBA
    17.4 Steppe

    Target: ITA_Rome_Late_Antiquity:RMPR117
    Distance: 2.6117% / 0.02611739
    77.2 GRC_EBA
    22.8 Steppe

    Also, two of the Rome Late Antiquity samples, RMPR36 and RMPR121, strike me as Illyrian/Thracian. They have less CHG/IranN and more steppe ancestry than the samples above. What else could they be?

    Target: ITA_Rome_Late_Antiquity:RMPR36
    Distance: 1.7826% / 0.01782552
    45.6 GRC_EBA
    34.2 Steppe
    20.2 TUR_Barcin_N

    Target: ITA_Rome_Late_Antiquity:RMPR121
    Distance: 2.0980% / 0.02097957
    53.4 GRC_EBA
    31.2 Steppe
    15.4 TUR_Barcin_N

    For comparison, I am providing the same model for the BGR_IA sample

    Target: BGR_IA:I5769
    Distance: 1.3613% / 0.01361292
    49.0 GRC_EBA
    27.8 TUR_Barcin_N
    23.2 Steppe
