Would you continue the family name?

Help! Even though we haven't conceived yet, I struggle with what to do! My husband is Robert IV. With it being our first child I kind of what the excitement to chose our own name, you know? I also don't like any of the nicknames of Robert or they have already been used in the family. His family really doesn't care if we continue it or not. But on the other hand, I would feel bad for not continuing it. What would you do?
