Claudia. Not overly popular and never has been. I've known only one, a girl I went to high school with. She was a perfect straight A student and went on to attend Princeton. I don't understand at all why your father would think of it as a joke name, but that's the way it goes with individual opinions, I guess. I would love to see a baby
Claudia.
But I don't think it fits with your top four girls. Completely different style.
