Marriage, death, and legacy
The name of Braose's first wife was Agnes, but her family is not known. His second wife was Elizabeth, the daughter and heiress of Raymund de Sully. He had two daughters with his first wife, but no children with his second wife, who outlived him. It appears that there was a son named William, who was the subject of a military summons from King Edward in 1311, but nothing further is mentioned of him after 1315. In 1316 a settlement of William the father's estates made no mention of this son making it likely that the son died before this date.
Braose died not long before 1 May 1326 and his heirs were his daughters Joan and Aline, or as she's occasionally named Alicia. Aline, the elder daughter, married John de Mowbray and Richard de Peschale. Joan married James de Bohun and Richard Foliot. Mowbray received the lands of Gower and Bramber before Braose's death.
Braose was known as a man often in debt and as being unable to manage his cash flow well. Thomas Walsingham stated in his chronicle that Braose was "very rich by descent but a dissipater of the property left to him".
Agnes married Sir William II DE BRIOUSE, 2nd Baron Braose, Lord Of Gower  [MRIN: 1649], son of Sir Wiliam I DE BRIOUSE, 1st Baron Braose  and Aline DE MULTON . (Sir William II DE BRIOUSE, 2nd Baron Braose, Lord Of Gower  was born about 1260 in , , England and died before 1 May 1326 in , , England.)
