AITA for still naming my son after his grandfather and great grandfather when my coworker's son (who has the same first name) died a week before my son was born? We are not close. Don't even follow each other on socials.

I don't mean to sound insensitive but I truly do not know how I would even possibly be seen as the AH but here we go...

My grandfather and my dad share the same first name, which was coincidentally the name of my coworker's son. I've always known my son would have the same name as my dad and grandfather. My coworker is in her late 40s and her 16/17 year old son was killed by a drunk driver while walking home from work a week before my son was born. I've worked at this place for two years now, and had only a year of experience when I went on maternity leave in April 2023.

Before my son was born, I'd received lots of personalized gifts, like a blanket with his name embroidered on it. We had a custom name sign made for his nursery. This name holds a lot of meaning for us. My grandfather was a single dad in a time where being a single dad wasn't common, and he raised three kids ages 5-9 all on his own.

I knew my coworker's son had been killed but I went on maternity leave the week before. She had a private funeral so I didn't attend because I wasn't close with her. I don't have her on social media or anything. We do not know each other outside of work.

She seems to think that I should have chosen a different name for my son because of what happened to her son. She called me out on it saying that I was being selfish for picking a name that holds so much hurt for her. I told her I was sorry that she felt that way but the name has special meaning to me and my family. She told me I was being inconsiderate of her difficult time and asked me if I even cared that her son was dead. I told her I did care and she said "just not enough to pick a different name for your son. Cool."

My coworkers are divided on the issue. My coworker ignores me and when I do talk to her, it's one word answers and she scoffs or sneers at me the whole time and mutters things like "fucking unbelievable" if I ask her to help with anything. HR is aware but because it's "a little issue of hostility with someone who is hurting" they haven't done a damn thing.

I don't know what I could have done differently. I don't think what I did was awful or should be considered an AH move. Was it?
