I have used Claude Guillot (pronounced gee-oh with a hard 'g' [instead of the soft 'g' which sounds like a 'j']) because of a guy I went to college with who was self-important and superior and smug and very irritating. (He dropped out before he finished the first semester). I also made him use 'DuBois' (pronounced doo-bwah) when he was using a false identity.
But whatever you come up with will be fine. If he's going to be a major character, may I suggest 'Michaud' for no particular reason?
