I have suddenly fallen in love with the name Johanna, but I prefer a version that I think is old French - Jehane. I can't remember where I've heard or seen it but I think it's very beautiful.
But... is Jehane too odd? Would it be difficult for people to pronounce? How would you assume it was pronounced if you saw it written down? Is Johanna better? (I don't like Joanna etc - I really like that h in the in the middle for some reason).
