Would you be mad?

So I am a teacher and at my previous school, that I left two school years ago, one of my close coworkers was pregnant with a little boy. We talked about many names that she liked, one being Cohen, and I immediately loved it! She ended up naming her son something different than Cohen. My husband and I have made list after list, yet we keep coming back to the same name, Cohen. We don't know if we are having a boy or girl yet, but if it is a boy, we want to name him Cohen. Do you think you would be mad if you were my old coworker and heard that I named my son this? I had not heard this name until she mentioned it, as it isn't common. We still remain friends on Facebook but we do not interact often, so she would obviously see.
