Well the Romans overnamed a lot of areas for simplicity. Macedonia was enlarged-Asia Minor's Gallia was enlarged. I guess if the Romans ruled America they would have combined New York, New Jersey and CT as "New York". I did not comment as to the Romans reasons for renaming the region. Just on the origin of Palestinians and Palestine. Clearly history shows they were a coastal people/region. Nor were the original Palestinians Arabs -- they were in fact Greeks.

At the time of the Romans, the mid east was, in large part hellenized, but the Philitines did not originate from Greece. Rather, they probably came from Crete. In fact, there is considerable evidence that the original Philistines and Phonecians were one and the same.
