Boy Names!

Areli
So I am only 5 weeks pregnant and obviously don't know what gender the baby will be but I already have a 2 year old baby girl and this time around I am hoping for a baby boy. My issue is that the baby's father wants to carry down his name, Joe Gaven. It's not a tradition but he is trying to start it. I feel bad because I don't really like the name Joe. It's very plain to me and it sounds like a nick name. Also my family is entirely Mexican and I know they'll have trouble with Joe Gaven. Should I just go along with him and name our baby that if it's a boy or should I be the evil one and say no?
