Sometimes it takes just one celebrity, or celebrity baby, to change the sexual orientation of a name ... Cameron for girls springs to mind.
This kind of problem often comes up on the Interactive Polls - should Aubrey or Cameron or Taylor or Kennedy be male or female? Opinions seem to be pretty well divided, which would I suppose make these names acceptable for both. Except that we don't know if the poll respondents actually use these names themselves, so it can't be reliable for research purposes...
