K36 nMonte with use of the following ancient samples gives me ~13% of Wielbark:

When I include more of Bronze Age European samples, my Wielbark share drops to ~6%, but the problem here is that we are mixing Bronze Age "ancestors" with their Iron Age "descendants" in the same comparison:

========================
BR2 is a curious case because it always shows up for Poles in nMonte runs (as long as it is included in these runs). The original study also showed that it has the highest genetic affinity with modern Poles:
http://www.pnas.org/content/113/2/368.full
But a BR2-like population does not explain the majority of ancestry of modern Poles.
Only something between less than 1/5 and ca. 1/3 (depending on region of Poland).
