Talk to cousins about middle name?

I really want to use my grandmas name (she passed away last year) for the middle name of our baby girl. The only thing I’m concerned about is my cousins. I am one of the only cousins to have kids so far since I’m one of the oldest, so I don’t want to steal the name. I’d be totally fine with any of them using the name as well since it’s just a middle name. I just don’t want them to feel like they can’t use it or like I stole it for myself. I don’t even know if they would want to use it. Do you think I need to talk to them about it? None of them are really ready to have kids, so I feel like it would be a strange conversation.
