DD is called Joanna (Jo) - but would have been Joe if a boy. It's not why we chose it, but I like that it's a bit androgynous.
I think girlie pretty names are lovely but would worry about giving my child one without knowing her personality. Likewise the risk of choosing a very blokey name, although they're fewer. Imagine the poor specky, weedy kid saddled with Thor....
Now we're expecting a second, what are other good androgynous/interchangeable names? I have Alex (ander/andra) and George (/ina). Any more?
