Help! Sierra Leone

[Candolim_Imp]

My partner's grandfather was Henry Williams of Sierra Leone. He married Catherine Colebourn in Liverpool in 1915. Henry was listed as 23 years old, ship's fireman, son of John Williams, Carpenter. We have been told that Henry held Sierra Leone AND Liberian passports. We are also told that he came from Freetown.

I have absolutely no idea how to proceed in tracing Henry's African background, but the name suggests he descended from one of the American slaves "repatriated" to Freetown, Sierra Leone after the American War of Independence when a large number of former slaves who had fought for the British ended up workless & homeless on London streets.

There are some Williams' on IGI who I'd like to think are linked to Henry, but I have no proof at present
