He held in addition to his patrimony the lordship of half of Barnstaple, acquired through his mother, coheir to the barony. In 1158 he had offered the king a fine of 1000 marks for twenty-eight knights' fees as his mother's share of her inheritance, and when he died he still owed £430. William (II)'s marriage brought him the lordships of Brecon and Abergavenny on the southern Welsh marches as his wife's share after the deaths of her two brothers. William (II) de Briouze concentrated his energies on his Welsh marcher lands, serving Henry II as sheriff of Herefordshire, 1173–5. The marriage of his daughter Sibyl to William de Ferrers, earl of Derby (d. 1190), indicates the status that the Briouze family enjoyed.

William was very fortunate in his marriage to Berta. All of her brothers died young without heirs so she brought a number of important lordships to the de Braoses in 1166. These included Brecon and Abergavenny. William became Sheriff of Hereford in 1174. His interest in Sussex was maintained as he confirmed the grants of his father and grandfather for the maintenance of Sele Priory and extended St. Mary's, Shoreham.

Roger is a witness to a charter of his brother William. (Dugdales "Monasticon" iv, 616 per Elwes)

From c1173 to 1230 successive fathers, sons, and younger brothers called de Briouze were feudal lords of Abergavenny. William de Briouze, the first of them, who derived his name from his lordship of Briouze in Normandy, married the sister and coheir of the 2nd Earl of Hereford (also daughter of 1st Earl) mentioned above, which seems to account for his coming into possession of a lordship in that part of the Welsh marches. [1]


William de Briouze (e), Lord of Briouze in Normandy, and of Bramber, Sussex, son and heir of Philip de Briouze, by Aenor, daughter and heir of Juhel son of Alvred, Lord of Barnstaple and Totnes. He married, in or before 1150, Bertha, 2nd sister and coheir of William of Hereford being daughter of Miles of Gloucester, 1st Earl of Gloucester (sic. Earl of Hereford). Sheriff of Hereford, Easter 1173-75, at which earlier date probably he already possessed the Lordship of Over Gwent. He was living in 1179. [2]

(e) Briouze-Saint-Gervais (formerly Braiose), arrond. of Argentan, dept. of Orne. His descendants spelt the name Brewes. In some 25 early references to this name, not in charter latin, it appears as Breouse, Breuse, or Brewys (the last of which still exists as a surname), but never as Braose, the form adopted in peerages, for which it seems doubtful if there be any good authority.

Note: The above text "1st Earl of Gloucester", which was part of a correction in CP XIV:6, is a mistake; Miles was Earl of Hereford.

 !RESEARCH NOTE: There is no indication in any of the above quoted sources that
there was a Giles or Roger belonging to this family. Also there is some doubt
whether the above Reginald has been mistaken for the Reginald who married Grace
de Briwere who is actually grandson of the above couple. In the case of child
#1, Bertha, there is also some quandry as to whether she belongs to this couple
or to William, child #2, and whether she married William Beauchamp or Walter de
Beauchamp. There are also some indications that this Bertha is the daughter of
the above couple who married Adam de Port. Because of the sealing action
previously taken, their names will be left on this compilation until better
evidence is made available.
