How can you change your husband’s mind about your son’s name?

"My husband is dead set on naming our son after him, making him the 3rd. I feel like being the 3rd would make him sound stuck up, like royalty. I don’t want to name our son after him and I want to give him his own identity. How can I get my husband to accept and go along with this?"
