Lyonel Frey

Second son of Ser Emmon Frey and Lady Genna Lannister, and so a grandson of Lord Walder of the Crossing on his father's side and a nephew of Lord Tywin on his mother's. An anointed knight, he was wed to Melesa of House Crakehall, who bore him no children. When Lord Tywin granted Riverrun to his sister's husband after the Red Wedding and the elder brother Ser Cleos was cut down on the road from King's Landing, Ser Lyonel was set third in the line of inheritance, behind Cleos's two young sons Tywin and Willem.
