I knew a girl in HS whose name was Pretty. She actually wasn't pretty, and she was quite mean.
To me it seems cruel to give a girl a name like that. If she is pretty, it comes off as superficial and conceited. If she isn't, it only serves to highlight her lack of beauty, and provides fodder for childhood teasing and humiliation. Kids can be very cruel. Perhaps her meanness was a product of how she had been treated.
Many years ago, a couple of co-workers told me of a rather homely girl that they went to school with who had the misfortune of being named Aphrodite. She, too was said to be not very nice.
Remembering how badly unattractive girls were sometimes treated when I was a kid in school, even without having unfortunate names, I think I might have become mean too if I had endured that. I was chunky, nerdy, and generally unpopular, so I was the recipient of quite a bit of childhood cruelty myself. But I think the homely girls still got it way worse than I did.
