Can I marry Carlotta Valentia in Skyrim and if so, how? [duplicate]
Solution 1:
She's not on the list of potential spouses at http://www.uesp.net/wiki/Skyrim%3aMarriage, so that means no, it is not possible to marry her.
Solution 2:
If you are using a pc it's
addfac 19809 1
Through the console (adds selected NPC to the marriage faction). Might be glitchy, but probably not with Caroletta.
