Heh, I think Duchess is an obvious one. She only likes the most expensive of everything, has a bizarre taste in fashion, and wants to be waited on hand and foot. So I'm thinking she'd prefer France. I imagine she'd fit right into King Louis' court at Versailles. I'm not a historian who knows each of the many "King Louis", but she'd fit right in with whichever one was most spoiled and arrogant.
I do know that there were a number of King Louis' that were just that.
