Husband wants a Jr.

I'm pregnant with our 3rd child and we are hoping for a boy. We have 2 girls together and he has 2 boys from a previous relationship. He is pretty adamant that if it's a boy, he wants him to have his name. I disagree. He has a nice name,but for some reason it just seems so weird or awkward to give my son the same name. I was hoping to use the names we picked with our previous pregnancies. He never suggested this before. Am I wrong for not wanting to name our possible son after him?
