Please don't give her a boy's name, OP. It was bad enough growing up with the feminised (and often mispronounced) version of a male name, without an entirely masculine one! It's very annoying when you are regularly mistaken for being a boy at school and, later, job interviews as a teen. It's very annoying, even more so if you're excruciatingly shy! Throw in the fact that one of my parents told me that, "I didn't want a daughter, anyway", and you can understand why I had already looked up 'how to legally change your name' by the time I was around 12.
I now have a clearly female name.
