BR2 (J2a1) is at the tail end of the French, but it looks as if the sample is south of the Hungarians...parallel to some Bulgarians and Romanians, but west of them.
In the PCA on page 9, interestingly enough, BR1 plots quite a bit north of approximately where BR2 was...still with the French, but this time parallel to the Basques, just east of them. Nowhere near the Orcadians, however, much less north eastern populations like the Lithuanians.
Isn't this strangely reminiscent of the results for the "Thracians" in that paper that were felt to be too badly analyzed, or so fragmentary, or unreliable once again because they were "projected" onto modern samples, or whatever it was, to be taken seriously? Maybe there were problems with them, but when seen in the light of these new samples, there's a definite western European signature to these new Bronze Age people who show up in the Balkans and also in Hungary.
