The only Thor I know is the God of Thunder. I note in the credits it's written as Thorley - well, still no wiser. Is it a typical American name? Yeah, I'm English, so maybe I'm just not up on typical american names....... And while we are on the subject, is Jeb short for something? not come across that one before either. Any Thors or Jebs out there?
A rather famous name from the U. S. Civil war is Jeb Stuart.
