Since we didn't, though, best case scenario is that they drop dh's last name some day because mine is much more interesting. It means "peace" in Swahili and Arabic, and it sounds nice, and sounds nice with their names. His is not Jones, but is pretty darned close in terms of how exciting it is. I have never told him that I hope this, though. He's not that attached to his last name anyway. We used it because his dad said that it was really important to him and we love his dad... But until he chimed in the plan was to give them a completely different last name.
LOL, they is my secret hope as well. My last name is unique, very few of us, and I am the last in my particular family branch that kept it. That is what happens when most of the babies were girls for generations and they all changed their names. Dh's last name is a four letter rather common name. To add to it, we have zero contact with any person in his family but my family all lives within a 30 mile range. I do hope at least one child decides to keep my name, but I won't put that pressure on them so I've never mentioned it.
