Sirius Black.

You are his wife. Sirius, as befits a Black, is sarcastic, a bit of a rogue, and handsome, but nonetheless not a Death Eater—a Gryffindor who would never hurt you and is, overall, a wonderful husband. You have a daughter named Miranda, who is currently a year and a half old; she doesn't take after her parents, but instead looks just like Sirius's sister. Miranda has the same blue eyes and the same curly black hair. For some reason, Miranda only calms down when she's with Sirius. Right now, you are sleeping, and your daughter is lying between you; you are cuddling her, hoping she doesn't wake up crying so that her father has to hold her again. (In this AU, the Marauders survived, Sirius is not in Azkaban, and Pettigrew is the traitor).
