Related interesting fact that I recently learned.
Supposedly, one people of the Sea Peoples were the Peleset, as the egyptians called them (https://en.wikipedia.org/wiki/Peleset), which are believed to be the same people as the Philistines, for which the Romans gave Palestine its name.
Another tantalizing possible connection for two other Sea Peoples groups, the "Sherden" and the "Shekelesh" sure sound pretty close to "Sardinia" and "Sicily", but I'm not sure if there's any actual evidence besides similarity.
