There probably is, somewhere. I vaguely remember an old topic (before archiving) where liana (who translated the game) mentioned something about the names and how they dealt with this. She'd probably know all the names, but I'm afraid that I don't.

I'm also wondering if the names are set from when you start a new game, or if there's any particular point in the game where the names are decided upon. I started a new game last night and got to the point where you can recruit the mechanic... and got "Indy" again! Reloading a save prior to entering that area didn't seem to change anything.
I'm kind of particular with names in RPGs, so yeah. I'm assuming there's no renaming NPC like in Metal Saga?
