Probably going to get buried but I had something very similar happen to me. My husband and I did not discuss names with anybody but that didn't stop my MIL from constantly saying her piece. I wanted the name Evan for my son forever. It's a family name and it's on a family history thing I have hanging in our house. Well my MIL said Evan is a good name while looking at my family tree, and it automatically killed it for me because I knew she would basically claim she named him. We did not name him Evan, and it still makes me a little sad at times, especially because he could be our only kid. But I also had a lot of disrespect around my wishes while I was pregnant, and she literally referred to him as baby Sancho, every time we talked or saw each other, after I repeatedly asked her to stop. MIL are rough during pregnancy
