Giving your 3rd child a family middle name when the other two don’t have one

My question is, do you think it’s ok to honour a family member by using their name as a middle name for your third child when your older children don’t have family middle names? Would this be ok?

I think it is perfectly fine. DD1 has an honor middle, but I don’t plan on giving DD2 one. I don’t see any potential conflict (among family members nor siblings) arising from it.

Why wouldn’t it be okay? Are you asking out of concern for your children or for other relatives?
