I've been chasing up what happened to free black people in Georgian England. Very little came up, except that feeling against slavery was particularly noticeable in London, where there was a largish community, so I can exclude London from bell ringing. They were more likely to intervene to prevent "slaves" being subject to extraordinary rendition. (Notes on an exhibition in the Guildhall - most interesting bit a possible link between high numbers of adult baptisms and freed black people. Meanwhile American states were banning such baptisms.)

Bristol and Liverpool were more likely to be anti-abolition. Nothing is known of the black people in Bristol. There is a rather negative paragraph which suggests that any intercourse was between sailors and local women and marriage would not be acceptable in polite society, so the community faded away. Or assimilated at a below polite level, I suppose. Family history research is not going to show up any of these people as their origins were not asked for for official documents.
