Or Summer could have chosen to keep her maiden name after marriage. My mother did that. And I carry both my father's and mother's surnames. Actually, most women I know keep their maiden names after marriage.

It all really depends on Vale's and more specifically, Patch's naming tradition.

Here in Argentina it has been legal for a while now that the kid not carrying the father's name doesn't mean neither that their parent's weren't married nor that the father didn't acknowledge them. A kid can have the surname of the father, the mother or both.
