I'm the mom and kept my maiden name. We both decided early that our child would have his last name and my last name as the middle name. Then over time we both threw name possibilities at each other...if someone said no that choice was done. Both of us think we brought the name we ultimately chose to the table.

But after we shared the name with my MIL, she said my FIL (who passed many years ago) originally wanted to name my H that name, and changed his mind at the last minute. So in our case, I fully believe my FIL won the name game in our family, sending us that name from the other side. And it's the perfect name for our child.
