Names for short stories

hmm.......... hmm............ I cant think of good names for northern barbarians. Im trying to get into writing books, but since I'm taking baby steps I am writing short stories for my creative writing class. I want to write a story about two enemies who are forced to work together to survive. However, during the course of their misadventure, they begin to respect  each-other and (thinking the other is dead) carry letters to the old enemies family where they are both killed. The story is meant to be sad, but awesome. I need help to think of names for a Barbarian, fur wearing warrior. Also, it would be helpful if somebody came up with a name for a lieutenant of a roman like army.
