I predicted R-PF7563 in anthrogenica, so I'll stick with it. DNA sample has been taken, they just have not published it. This quote is very interesting.

If the royal family was E-V13, I don't see how the results would be upsetting given that modern Greeks are high in it. Same argument for J2a. I would say R-PF7563 odds got better. The Macedonians and their royal family rose as adversaries to the Illyrian tribes that invaded the area in 750 BC. These Illyrians so far are linked to R-BY250 and R-CTS1450(undetermined downstream).
