General Notes

William was only 12 when his father died.  The wardship of William andthe de Braose lands were granted by Henry III to Peter des Rievaux.  Onhis fall in 1234 these custodies were passed on to the king's brotherRichard, Earl of Cornwall.  When William came of age he took control ofthe Braose lands in Gower, Bramber and Tetbury.  He confirmed the grantsmade by his father of the rents of cottages in Tetbury (they are stillthere) to the priory at Aconbury, founded in the memory of Maud de StValery by her daughter Margaret.

He was plagued throughout his life by a series of legal battles over landrights with his female relatives.

See Cottages of Tetbury.


William de Braose, in the 41st Henry III [1257], when Llewellyn apGriffith menaced the marches of Wales with a great army, was commanded bythe king to defend his own marches about Gower, and the next year he hada military summons to attend the king Chester. In two years afterwards,he was again in arms under Roger de Mortimer against the Welsh, and wasone of the barons who became pledged for King Henry, abiding the award ofLouis, King of France. He d. in 1290, leaving by Isabel de Clare, hisfirst wife, a son, William de Braose.

Peter de Braose, half-brother of William, Lord Braose, of Gower. Peter'sson, Thomas, was found heir to his grandmother, Mary de Ros (hisgrandfather, William de Braose's 2nd wife). [Sir Bernard Burke, Dormant,Abeyant, Forfeited and Extinct Peerages, Burke's Peerage Ltd, London,England, 1883, p. 73, Braose, Barons Braose]

NOTE: From the above information it is certain which William de Braosewas Peter's father, for only this one William was summoned to parliamentas a baron. However, in attempting to connect Mary de Ros to William,there are some pretty glaring date inconsistencies. e.g., William died in1290, and Mary wasn't born until around 1298. It's possible theapproximated year of birth for Mary is somewhat off, but surely not thatfar off. According to Burke, her father, William de Ros, was b. 1255,thus, she could have been born as early as perhaps 1271. Her father d. in1316, and her grandfather died 16 June, 1285. Her 2nd husband, Thomas ofBrotherton, was born 1 June, 1300. Had she been born as early as 1271,she would have been 29 years older than her 2nd husband. It's almost asif there had been two separate individuals named Mary de Ros, yet Burkesays "Mary m. 1st, to William Braose, and 2ndly, to Thomas de Brotherton,Duke of Norfolk."
