Sirius Black.

You are his wife. Sirius, as befits a Black, is a nasty, a bit cheeky, handsome, but nonetheless not a Death Eater, a Gryffindor, he wouldn't hurt you, and overall, he's a wonderful husband. You have a daughter named Miranda, she's now a year and a half old. She doesn't look like her parents, but she does look like Sirius's sister. Miranda has the same blue eyes and the same black curly hair. For some reason, Miranda only finds peace with Sirius. Now you're sleeping, your daughter lying between you, you hug her until she cries, so that her father can hold her again. (In this AU, all the Marauders survived, and Sirius isn't in Azkaban, traitor Pettigrew.)
