Sir Bran de Lis - more properly Bran d'Iles, but often conflated as Brandelis - was the son of (Gilbert of) Norroiz and the brother of Gymaoure and Tyrry.

This led to Gawain slaying the lady's father and two of her brothers in combat, but a similar challenge by Bran was postponed because of his wounds. When they at last met five years later, Sir Lionel, Gawain's young son and Bran's newphew, tried to stop the proceedings, but the fight continued until King Arthur intervened and brought a halt to matters. Sir Gawain and Bran then became friends. Sir Bran fought in the wars against the Gaulish King Claudas and the Northern invasion of King Galeh
