All people are of African origin on a very long timescale of over 50,000-300,000 years ago.

That there were Africans in a more modern Britain sooner (just 5000 years ago), is interesting for this reason and it begs the question as to where the population went to-

I'm guessing they married out.

I cannot find a reference, but I seem to remember learning that eighteenth century Covent Garden in London had a significant black population, possibly former slaves freed by and then recruited into the British Army during the Revolutionary War. Within a century, that population had gone, at least as a distinct, visible group: the original population were all male and had taken local wives.

That's presuming these folks remained a distinct population, rather than assimilating.
