Ser Jaime Lannister squired for Sumner for four years; Merrett Frey was also sent to Crakehall as a page and made a squire by the lord. During the campaign against the outlaws of the Kingswood Brotherhood, Merrett was captured by Wenda and Lord Sumner had to ransom him back. After receiving a hard blow to the head from a mace, Merrett was no longer able to fight and Sumner sent him back to the Twins. Jaime saved Sumner's life in battle with the Brotherhood when he stopped Big Belly Ben from killing the Lord of Crakehall.
