You might call them a Greek enclave. It has an interesting http://history.It's called Tarpon Springs and was established as a Greek Sponge Fishing Village in the 1860's. Most all today are American Citizens, keeping the old traditions, proud to be Greek-Americans. They have a large Greek Orthodox Church here and still put on the old fashioned underwater suits with the big brass helmets and a guy on the boat pumping air. It has become a tourist attraction and people are taken out in boats to watch the sponge divers. Also, there is a warm spring in the middle of town, which attracts manatees in the winter. So, you'll get tourists snapping away at the sea cows. I particularly love the grizzled old timers who sit and talk Greek to each other. Strangely enough, they are not resentful of the newbies (anyone here less than 50 years) because their kids are all Americanized. Almost all are bilingual. Also, a yearly event is held here in the Orthodox Christmas which occurs in January. Teen boys from all over the country and a few from Greece come here. The Greek Bishop throws a cross into the bayou that has the spring and the boys jump in to retrieve it. The one who gets it is said to have good luck for the year and is feted like a celebrity for a week or so. By the way, they made a pretty good movie here in the 50's (60's?) called Beneath The 12 Mile Reef.
Phew. That's probably more information than you expected.
