My family is from Sierra Leone, but we do have a legend of sorts. I think it’s true, but because of the civil war that happened there, it would be quite difficult to get information from Sierra Leone.

“My grandfather’s father was supposedly a half-Scottish, half-Greek man. It’s not clear how or why he came to Sierra Leone (my guess would be missionary work). I think this is probably true because some of the oldest members of the family said it, and because the name Pericles Macauley (his name) is one that has been passed down.
