Catherine, Katherine, Katharine or Kathryn?

My favorite is [name]Kathryn[/name]. Could be because it’s the name of a very close friend or because I like what I call “droopy” letters. I also feel that this spelling has more spunk and personality to it than the traditional [name]Katherine[/name]. That said my second choice would be [name]Catherine[/name] - I prefer the traditional French spelling to the English one.
