Boyfriend wants to name boy after himself

So I'm 33 years old and only 6 weeks along so far. I had 4 miscarriages when I was 19-20 years old (with someone else). I don't have any children and honestly this will be the only child I'll have. My boyfriends name was passed down 3 generations. He's dead set on passing it down again if we have a boy. But I won't do it. I've made multiple lists of boys names and he won't have it. I personally think the whole concept is outdated and kind of pretentious. His mom doesn't even like the idea of it. She didn't want to do it herself and doesn't blame me for being against it. Especially if it'll be my only child. Not only does the concept bother me (this kid will be his own person...not a 4th copy) but it's also like the most basic name on the planet. I can't even put his family tree together because of how common his family name is. I know it's super early to even care about this...but it really does bother me. I was hoping for a boy, but now I'm afraid to find out it's a boy because I know this whole thing will come up again. I just feel like, I'm growing this baby and pushing it out after years of thinking I'd never have any kids... I need to put my foot down on this. I just don't know how to win this fight. 😕

I refuse to name my child James Oswald Lynch IV. 😒
