Everyone in my family seems to have done this at some point. Same with DP's. He was quite shocked to learn that I didn't automatically assume that the baby would take his name if it were a boy
I'm named after my mum, have a brother named after my dad, and my brothers and sisters except one have done it too. Always the boys taking the fathers name though, never girls taking their mums names. DP is also named after his dad. Seems to be sort of a family tradition but not neccessarily one I feel the need to continue.
Any opinions on this?
