I'm very close to my SIL. She and DB are expecting a boy. DB wants to call him our father's name. He passed away when we were teens so he'd like to name his son after our father if not at least use the name for a middle name. My SIL on the other hand hates this name and refuses to use it because when she was younger she had a very abusive relationship with someone that goes by the same name. She doesn't want it to be featured at all in my future nephew's name. The name isn't particularly unique but then again it's not something like Thomas or James, or any other popular name. DB thinks she should just get over it as it's not as if they're calling him Hitler (his words) but she doesn't want it. I know it greatly impacted her at the time but if calling your own son by his name will bring back traumatic memories then she's justified, IMO.
