Question about naming a baby

Chelsey

Okay So my husband has an older son that is not biologically his but he gave him his name at birth just not with jr after it and with the mothers name before my husbands last name also well now me and my husband are having our first son and my husband wants to name him after him with jr after it so it is 100% after him do you feel like hat would be okay to do? Or would you feel weird like maybe his ex or son would have an issue with it?
