Sergeant at Arms
Note -- if they're only engaged and not actually fully married yet, if a minstrel tells you this you can talk to the husband-to-be and challenge him to a duel for her hand. She may not like that though, depending on her personality. To wed Svipul I had to fight off three other Jarls, the third actually betrothed to her out of the blue, but I got in before the wedding to break em up. She liked me beating up her suitors and I sort of wondered if she accepted other men so she could see me beat them bloody.
