They were no Sicilians!
Compare haplogroups of the Thraco-Cimmerian sphere (E-V13, R-Z93, N) with the rest of the samples, they have a different autosomal profile (steppe, Caucasian and Central European-North Balkan) than both the locals and the Greeks:

The locals and the Greeks were clustered within "Mediterranean", the Thraco-Cimmerian related groups score Central European-North Balkan, Caucasian and steppe respectively, irrespective of haplogroup (like one Cimmerian R-Z93 and Thracian E-V13, both being "Caucasian"). How exactly he scores, we will see, probably more Thraco-Cimmerian than actual Caucasian, because the older N Thraco-Cimmerian sample, IR1, was also mixed steppe-Caucasian-East Asian.
These mercenaries stick out, totally, but not by being more Southern or Levantine, but more Northern and steppe primarily, sometimes more Caucasian secondarily.

A unit of Thraco-Cimmerian mercenary cavalry being slaughtered in that battle of Himera, that's the best explanation. The combination of Thracian E-V13 with quite obvious Cimmerian lineages is just striking.
We got some accounts for that:

From the current paper:
They used isotopic data - both genetics and the isotopic profile tells us, that they were not locals:

So yes, they were no Sicilians indeed. Whether they were Thracians (especially the Central European-North Balkan E-V13 individuals) is another matter. They could have been Veneti or other people too, but given the context, (more Northern) Thracian is just more likely, coming together with obvious Thraco-Cimmeirans/Cimmerians/Scythians and probably forming together a mercenary cavalry unit.
This result makes a strong E-V13 presence in early Greeks indeed very unlikely, because this is a solid sample and the only E-V13 carriers are obvious foreigners. We'll have to see what's up in more Northern areas of Greece and other regions, but this is the first solid argument against a significant E-V13 presence in classical Greeks.
