In "Cold Mountain" - the book, not the movie, haven't seen the movie, whole other rant - there is a character who has acquired the sobriquet of "Stobrod" because he was beaten with a piece of wood, so I think the "stub of a tree" thing is right on.
A couple of Irishisms are "the way that" and "how be". My dad would say "how be we go for a drive..." or whatever. It was, of course "how would it be if". "the way that" would be used as we would say "so that" - eg "I went yesterday, the way that I wouldn't meet him there today".
