CELT: Welsh Goblin seeks etymology

[Andrew Smith <hobbit@MAIL.EARTHLIGHT.CO.NZ>]

I have been working through Herman Miller's Zarkhand list, some words in
Brithenig that can be adapted to roleplaying would not go amiss, but
finding the right word for 'goblin' is causing to be tricky.  I think it
should be derived from bwca or bwgan (Gaelic bocan), but I can't find a
reliable etymology for the word to find the Brithenig form.  Does anyone
have access to a reliable source?
