Bit late, but I also agree with Breather: if a full name isn't revealed in the books, we shouldn't assume it. For instance, Josie and Gertie could also be short for Josephine and Gertrude, but their full names are never actually said in the books. So we shouldn't just take them for granted. Otherwise things could get out of hand. (Like LilyLacreag said, his full name probably IS William -- but we don't know for sure.)
