I always understand the Samaritans were part of the sea Peoples invasion of Egypt, which would mean that were definitely mixed w the Semites, but from earlier origins than this article addresses.
Samaritans were most definitely not linked in any way to tye Sea peoples. The gap in time is nearly 700 years
The notion of the Sea Peoples are a modern myth, used to fill gaps and a role in the conventional pseudochronology. They were the Greeks.
