Advice on naming my baby

I had my baby girls name picked out before I got pregnant and now I’m pregnant with a girl and my cousin who I don’t talk too took the name 😭😭 it’s a rare name and one of my family members told her I liked it because I talked about it a lot and she doesn’t like me so she took it. She named her baby before I got pregnant and now I don’t know what to do. I cut her out of my life because she’s a toxic person so our kids will never meet but of course have the same great grandparents and aunts and uncles who don’t really talk to her much but still do talk to her. Do I still use the name or pick something else?
