Death and burial
He died between 1159 and 1163 but maybe as late as 1175, believed to have been slain by Seisyll ap Dyfnwal, a Welsh Lord of Upper Gwent, the northern half of the old Welsh Kingdom of Gwent. He was killed at this Welshman's home, Castle Arnold in the valley of the River Usk, on eve of Easter. His death, whether it was murder or in conflict, was avenged by his nephew, William de Braose, 4th Lord of Bramber in 1175 at Abergavenny Castle.
