The only member of the house to appear is Hallis Mollen, called Hal, a member of the household guard of Winterfell.
Hallis Mollen was made captain of the guards of Winterfell after the death of Jory Cassel. He joined Robb in his ride south, and was chosen to escort Lady Catelyn to Bitterbridge where she was to negotiate an alliance between the King in the North and King Renly Baratheon. He returned with her to Riverrun and was later sent towards Winterfell as escort for Lord Eddard’s bones. Given that Moat Cailin was shortly to be held by the ironborn, nothing is known about what happened to him or the others sharing the task.
