Whats in a name?

So my sister in law just had her baby today. They kept the name a secret until he was born. They named him Ethan Connor. I'm happy for them but I can't help but feel depressed because Connor is the name we had picked out for a boy before we knew what our daughter was when we were pregnant with her 4 years ago. After our daughter was born, we decided that our next baby if it were a boy, we'd like to name him Connor. I feel like they stole the name from us. Ugh, am I being selfish and silly to feel like this? I've been crying on and off all morning since I found out about his name. I feel like I lost someone. I really don't want to feel like this.
