When my sister and I were pregnant at the same time we both were considering using James as a boys name. I wanted it as a middle name and she as a first, so we both agrees that would be ok. In the end it didn't matter as she had a girl. What really annoyed me was my BIL and SIL using my kids names without mentioning it first (they have done this twice now) which I think is rude although it doesn't really matter. It just would have been nice to have been asked first.
