Lord of Stone Hedge and head of House Bracken in the War of the Five Kings, plainspoken and hot-tempered, twice widowed and thrice wed. Rode with Lord Hoster Tully in the Battle of the Bells in his youth, sat Robb Stark's war council at Riverrun, and helped launch his old liege's funeral boat into the Tumblestone after Hoster's death. His lands were burned by Ser Gregor Clegane and the Mountain's men early in the war, his harvest carried off, and one of his daughters set upon in the ruin of her father's hall.
After the Red Wedding Lord Jonos bent the knee to the Iron Throne and led the king's host against his ancient rivals at Raventree Hall under Ser Jaime Lannister. He had by then five daughters by three wives, a natural son, Harry Rivers, whose paternity the Blackwoods openly doubted, and a nephew, Hendry, his heir while no trueborn son remained. The siege ended in a peace brokered between Bracken and Blackwood, the first the two houses had kept in living memory.
