Yesterday I offered to answer your questions about Ocracoke (if I can).
The first question is "What percentage of the island population is made up of Ocokers as opposed to move ins? Do you have a rough estimate?"
I don't know for sure, but I'm guessing that about half of the current population consists of folks who have a long family history of living on the island. One of the old names for the island was Ocock. Thus the term "Ocockers," which is generally used to mean someone from an historical Ocracoke family who was born and raised on the island.
Until about 50 years ago, there were only a small handful of folks who had moved here from elsewhere. Often they were a little eccentric. Actually, they usually fit right in and helped make this quite a colorful place.
Look for an answer to tomorrow's question about the Ocracoke School. And if you have another question just post it here.
