I know this is an old topic, but it was one I was thinking about just yesterday.. I doubt they would be family names, as the boys seem to be too pragmatic for that. I imagine knowing they'd have to use them, for at least a year, they'd want names they were happy with and felt comfortable using. So Maz McCoy's story seemed eminently plausible to me. I really do like the names, and they seem to fit them, so good choice boys.
