One of my boss's best mates was a Kelly.

I say use it. People are going to ask you if its a boy or girl anyway - even if they are wearing a very boyish looking outfit -you'll still get - oh what a cute girl

I've never let anyone change my opinion if I love a name - well except for a kiwi friend that i had at work - Aricyn was going to be Reznor - but with her kiwi accent - it sounded soooo wrong.. lol.. like.. rissna... it put me right off...
