Unique Girls Names

In my family we are up to eleven generations of variations of Elizabeth. Pretty amazing, hu? Anyway, ever since I learned of this around 13 or 14, I've been searching for Elizabeth diviations, that haven't been used. My favoriate has been Elspeth. Which I think would go nicely with Grace. It's really not at all common, I've known one, she took care of me when I was little. Good Luck! :)
