Do you know anything about the Fomorians? They were black and supposedly attacked and captured part of Ireland? Further, I have read one anthropologist speculate about Leprechauns, he said that the Bushmen were the original Irish and the source of the legends of the Leprechauns. I went off and read a lot about the Bushmen, they do fit the bill.
The African Bushmen are in fact Asians and their young have the tell-tell Mongoloid spots on their backs. They are small, have pointed ears and could be described as impish. There are no more pure Bushmen, they have intermingled with the Bantu (blacks) of Africa.
(your thoughts on this?)
I have this wonderful book, titled "The Celtic Heroic Age", which is a compendium of historical accounts of the Celts. There is a great quote from Strabo, in which he says the Irish like to eat their dead and do the whap-a-dang with their siblings.
We came from a fun bunch.
