An interesting exercise
Going into the Perseus classical map project and using the various
words that may be derived from the word Pela(s)goi yeils the following
results at

Palaikastritsa is in Corfu
Palaiikastro is in Eastern Crete
Pelikate is on Ithaca
Phylakopi is in the Cyclades
Plaka is on the tip of Attica
Obviously many of these have good Greek etymologies, but the spread is
interesting.
With the Greek habit of dropping (s) (eg Tyrrsenoi to Tyrrhenoi)
dropping it from Pelasgos gives Pelagos = coastal. Another reference
to "People of the Sea" perhaps? I wonder if that could mean anything?
Just kite flying
