I do agree about the -e, and I shudder at
Fae. So far, so good.
I've only ever known one
Fay, and she was large and bossy. But, I know a
Tessa Fay who's dainty and beautiful and a very talented pianist, which is a whole lot better!
I think that if you know or suspect that you might have a child with a particular temperament or physical features, it is wise to avoid names like Beauty or
Modesty etc.
