I think you can rule out a Welsh origin. That particular
Lee family were travelling Romnichal - British Romanies, who have a tradition of highly unusual names. I also found an Alefare
Smith married in Hackney in 1849, and
Smith is another common Romany surname in the UK. So there's another possible origin.
edit: and an Alifear Byford who's also from a Romany family - and an Alafear
Wright b. 1839: can't confirm her being Romany, but there are definitely Romany Wrights (there was a fairly well-known Romany maker of wagons/vardos called
Wright). Of course this may have nothing to do with the US names, but it's looking like a good possibility.
Wild guess, from what I know of British Romany names - could have originally been a corruption of
Alethea.
edit #2: Another possible origin for the US names might be a former Native American tribe from the Florida region, the Alafaes (also Alafay, Alafaia, Elafay, Costa, Alafaia/Alafaya/Alafeyes Costas) - those variations look closer to the OP's set.
