In southern Africa it means 'a house' and sounds like KY-ah. If you put 'piccaninny' with it, then it means 'a little house', which if you are being not-so-polite actually means a toilet or outhouse and abbreviates usefully to PK, so people ask where the PK is.
Of course, this is no reason to avoid it. But it prevents me from thinking of it as a human name, or any kind of name actually.
