Somewhat related was this article from ~2013 in TheAtavist [0] about Tangier Island in Virginia where they also still speak in an Elizabethan accent. It's about a director going to try to convince the locals to record lines from Romeo and Juliet so he can recreate it with vocal coaches and make a "authentically sounding" production. It's an interesting read, about 25 mins.

IIRC there's also a community in Maryland with the same (or similar) accent.
