How to get English speaking miniorities compared to Eastern European German miniorities with latest possible POD? I think such miniority to survive should be religiously distinct (so no Catholic refugees who could assimilate easily among other Catholics), perhaps some sort of English analogue of Amish/Mennonites. There really were religious exiles from British Isles (some of them settled as far as Poland) but due to tiny numbers they quickly assimilated. IOTL religious dissidents from England could just emigrate to America so they should have this option closed-either England is officially Catholic and bans non-Catholics from settling in colonies, or less tolerant to non-Anglican protestants, or have no settler colonies at all. Other question-where would such miniority settle on European mainland? My bet-Poland or Russia.
