    So it doesn't look like very recent immigrants, but rather like British with full and in part Ashkenazi ancestry.

    For the Germans there are mainly outliers in the direction of Balto-Slavic, but in their case its hard to tell whether they are e.g. East Prussian Germans or Germans with recent Baltic or Polish ancestry.

    We are using K13 coordinates, why donīt you make PCAs or graphs with the K13 coordinates we have, instead of using G25 coordinates indepently if we have those samples in G25, we are analizing K13 coordinates, not G25 ones.

    We have alternatives to screen/sift (?) samples without using their G25 coordinates.

    Distances and results to usual references could be indicative, plotting in PCAs (and similars) too, and graphs of similarity are quite indicative an avoid any prexisting bias in references, for example:





    After seeing these ones, I think itīs quite clear which ones should be used preferably to be part of the average reference.

    So finally, do you think that those are the best individual samples to make an average with them?

    They are ok, but we have better English samples already with less outliers.

    Those ones can be added to which you have.
