With Pelasgians is some kind of problem, because, no one exactly know, what greeks authors have in mind when they wrote abot this people - probably they themselves didn't knew. I mithology Pelasgians are sometimes some kind of Greeks, but sometimes they are showed as people different. So who they were exactly we dont know. BUT, this name is using as synonim pre-Greek settlemets - and very good! Before Greeks arrived people in this lands could be alleready mixed, but I uderstand, that the piont of all discussion is which gruop of people was the first? So I guess that it will be hg E, aspecially in southern part of Greece. In the north - who knows, it could be either I, G, or even J. Did the people E called themselves Pelasgians? I don't know, but some similarities between this name and some place-names in this region can in some part testify on behalf of that theory, because there are some vocal connections with Peleste and Pelishtim, ie Philistines. As it is known from egyptian and semitic sources, they were consider as migrants from Crete or some others aegean islands (like Kos) so it wouldnt be so strange if they were the settlers of others parts of the present Greece too. Btw, I dont remember exactly, but Philistines were pinted the same way as Egyptians were, so, they were similar in appirience, so, if they came from southern Greece, then the original people from that parts could be not only similar to egyptians but also has this special hg - E.
