Am I wrong

My husband has a very strong family tradition of using the first and middle names of grandparents, uncles, aunts, etc to use in baby names. For example, my father-in-law's name is Keith so my husband's middle name is Keith. The only name tradition my family has comes from my dads side where the middle name Stone has been passed down to the first born son for generations. My brother doesn't want children, let alone get married so I don't want the name to die with him. My husband thinks that's not our problem tho. I am not pregnant (it will be a miracle if I do) but when (being positive) it happens I will more than likely have a boy. What do yall think? Is he right to say that it's my brothers responsibility to get the name passed on? Or should I really stand my ground about adding the name to our son?
