Both Florence and Grace are relatively popular round here. Probably know about 8 Graces of various ages and every single one of them, without fail, definitely does not live up to their name. Half of them are dumpy, clumsy children. The others are right little madams with blonde/ginger ringlets and a habit of stamping their feet whenever they don't get their way. I probably wouldn't notice it, but for the fact of their name making me expect dainty, well-mannered children and being surprised that they are not.
I know a Florence who gets called Fliss for short, which I think is nice.
