William was the son of John de Braose and Margaret Llywelyn, grandson of four powerful families; William de Braose and Matilda de Clare, Llywelyn the Great, Prince of Gwynedd, and Joan of England. He descended from a turbulent history – his great grandmother, Mathilda de Saint Valery de Braose, was murdered by his great grandfather, King John Lackland. The family originated from Briouze in Normandy, descendants of Marcher Lord, William de Braose, who fought alongside William the Conqueror at the Battle of Hastings.

William married thrice: firstly to Aline, daughter of Thomas de Multon and Maud de Vaux. Her maritagium included the manor of Thorganby, Yorkshire. They had a son, William, heir and Lord of Buckingham.

Aline died after 1260, and William married Agnes, the oldest daughter of Nicholas de Moels and Hawise de Newmarch. Her maritagium included the manors of Woodlands in Horton and Knowlton in Dorset. Their son was Sir Giles de Braose who fought in Scotland in 1300.

His third wife was Mary, the daughter of Robert de Ros and Isabel d’Aubigny. Her dowry included the manor of Weaversthorpe, Yorkshire. They were married before 1271 and had three children:
* Richard, died by 1296
* Peter, died by 1312
* Margaret, wife of Baron Ralph de Camoys
* William, listed in some sources

William’s father died in 1232 before he was an adult. He inherited his father’s properties 18 July 1232, and came of age by 15 July 1245. Calculations make his birth approximately 1224.

He served King Henry III and Henry’s son Edward I as a councilor, and sided with King Henry against Simon de Montfort during the civil war. William was summoned to Parliament in April 1292 as Lord Braose, or Willelmo de Breuse. He fought in Wales in 1257 through to 1282. He was summoned to attend the King at Shrewsbury in 1283.

Braose was a benefactor of Sele Priory, giving the monks a half acre of property on the high road from Bramber to Chichester, and then 229 acres at Crockhurst in 1254 for the souls of he and his wife to the priory in exchange for 10 marks annually for tithes.

William died at Bramber or Findon, Sussex and was buried 15 January at Sele Priory. William’s eldest son, William de Braose, succeeded him as Lord and Baron, and his widow, Mary, received the manor of Tetbury which she surrendered to her son, Richard.
