Years ago I I remember readin about a group of germans that live in central jamaica for generations..and dey pretty much isolate themselves from the rest of the country and somehow manage to keep their heritage and language intact
Toussaint from the main board had sent me a link on someting similar...a group of Polish soldiers in haiti who build they village high in the hills..and 200 years later they kinda does still exist
