I used to know a girl named Geordane (pronounced geor-dahn). She is the only one I have ever met so far. According to her, her parents coinded it from their own names (Georgette and Daniel I think, I don't know why I remember such things!)
What do you think? I have always liked Georgia and Georgiana and actually I think it is a nice variant. Much more feminine than Jordan too, in my opinion.
