After 3 days of deliberating over our DD name we managed to come up with Sophie Victoria (Victoria being after the state i moved to, to be with my DP) then my last name as the 3rd name as we r not married and the fact we couldnt decide who's name should be first if we hypenated our last names. Then my DP's last name as her surname.

Abit complicated and unusual, but i like the fact that my last name will always be apart of her name whether she gets married or not
