    PCA vs. Map of Polish regions

    I collected Polish and neighbouring regional samples that I found (samples assigned to regions mostly based on genealogical info) and added some academic samples (Mazovia2 = seven samples from Warsaw from Behar 2013 study). I created a PCA. Then I superimposed this PCA with regional Polish and neighbouring (including East German) averages on a map.

    And after adding Lithuanian average to the PCA:

    Red Ruthenia are Poles from Lubelskie, and Polish Mountains are Poles from Podkarpacie.

    These are the regions I suggested to Living DNA:

    Vinnytsia, Poltava, Kharkiv, Chernigov, Boryslav and Zboriv are of course ethnic Ukrainians.

    Polesye, Grodno, Vitebsk and Mogilev are Belarusians. Zakarpattia are Carpathian Rusyns.
