Father:      Sir Peter de Braose of Tetbury (1273-1312)

Mother:      Agnes Clifford (~1275-1332)

Birth:      abt 1305

Death:      11 Jun 1362

“Mary: d. 11 June 1362 (The day of St. Barnabas, otherwise Saturday the vigil of Trinity.”1

Occupation:      Countess of Norfolk c.1334-1362

Spouse 1:

Sir Ralph Cobham of Ardington

Birth:      abt 1290

Death:      3 Feb 1326

Marriage:      abt 1320

Spouse 2:

Thomas of Brotherton, 1st Earl of Norfolk

Marriage:      abt 1334

“Braose was one of Edward III’s household knights, but even better, he had a younger sister Mary, a widow of a few years standing, with some well-placed manors of her own. The earl of Norfolk was only aged 34, and there was time to father another son and heir if he remarried. It was likely Braose/Brotherton double marriages that took place in the latter half of 1334. It seems improbable that Thomas married Mary before the summer of 1334, given the Scottish campaign of 1332-1333 and the lack of urgency to remarry while his son and heir Edward was alive.”2
