• Ser Brynden "The Blackfish" Tully, uncle to Catelyn, Lysa, and Edmure and head of House Tully — Deceased

The Tullys kind of faded out of the action in Game of Thrones after the Red Wedding in season three. However, Brynden Tully had taken back Riverrun from the Freys and refused to give it up, leading to his demise.
