I don't really see any compelling reason to suggest that you should use any of them over the others, or even to suggest that you use any of them at all. It's your story, so it only stands to reason that you ought to be the one to select the names used for the characters in the story. None of them are particularly appealing, but that doesn't really matter because the important thing is to get the story written. Should you decide to change the character's name later on, that would be rather an easy thing to do. Using a simple function like find and replace, you could immediately locate and change that character's name in a matter of seconds, so you're better off just getting the story completed and worrying about such insignificant things later.
