I have always thought that E-V13 individuals spoke dialects similar to Etruscan as well. Interesting analysis.
Maybe some of the Albanians were related to these Etruscan speaking people; but were later assimilated into an Indo-European culture. Which may explain why almost half of the Albanian Y-DNA is dominated by Bronze Age DNA (R1b, J2) while the other half is mostly Neolithic. (E-V13)
