Father: William de Braose

Mother: Matilda de Clare

After the conflict between King John and the Braose family, Walter and his three brothers were held in captivity.

In 1218, the council of magnates who were running the country after the death of King John ordered Bartholomew de Podio, seneschal of Angoulême, to release Walter and his brother Philip. (Patent Rolls Henry III Vol 1, p134)

Walter became a significant military figure in South Wales, having custody of the castle of Carmarthen in 1233. He died during the war of 1233/4 between the crown and Richard Marshall, Earl of Pembroke.

In 1222 he had married Hawise de London, daughter and heiress of Thomas de London. They had no children and Hawise went on to two further marriages, with Henry de Turberville and Patrick de Chaworth.
