I think Kahtrin has a pretty sound, but the spelling
Katrin looks prettier on paper.
There are some doozies in my family tree too, but not as weird as
Woody Isabelle. There's
Olympia Camille, Maxamillion (yep, spelled that way), Peirreine (girl named after
Pierre, I guess), Euphrasine, and Jean-Claude with a twin brother named Claude-Jean.
