Middle name for Matilda?

My boyfriend and I just found out were having a girl and my boyfriends name is Matthew so he's got his heart set on naming our daughter Matilda so that he has a mati jr. Since he's been hoping for a girl this whole time and his heart is 30x it's usual size right now I'm probably gonna go with it, Matilda is a cute name in my opinion but I need a middle name! Matilda ----- Warner.
