Sir WILLIAM de Breuse (-Findon 1290, bur Sele, Sussex). "William de Breous son and heir of John de Breus" was granted "a yearly fair at his manor of Horsham", dated 3 Aug 1233[1287]. "Domino Willilemo de Brawoso…" (presumably the donor´s stepson) witnessed the undated charter under which "Walterus de Clifford filius Walteri de Clifford et Agnetis de Cundy" donated land in Cofham to Acornbury priory, Herefordshire, for the souls of “Margaretæ uxoris meæ et dominæ Mathildis filiæ meæ”[1288]. "Willielmus de Breuse miles" confirmed a donation to Acornbury priory, Herefordshire made by “dominus Johannes de Breus pater meus" by charter dated 22 Jan [1290][1289]. He sat in the Parliament of 1290, whereby he is held to have become Lord Brewose. Leland quotes a manuscript which records the death in 1290 "apud Findon" of "Gul de Breosa senior" and his burial "in monaster de Sele"[1290].
