[WILLIAM de Brus (-1 Aug

---

). Priory of Gysburne/Gisborough. The obituary of Gysburne/Gisborough priory records the death "Kal Aug" of "Willmi Brus primi Prioris"[921]. Presumably William was installed as prior by Robert [I] de Brus who founded the priory and was presumably a close relation. Dugdale names "William who occurs in 1131" (without specifying the primary source to which this date relates) first in his list of priors of Gysburne/Gisborough, without specifying that he was "de Brus". If this date is correct, the chronology suggests that it is more likely that William was the brother, rather than the son, of Robert [I] de Brus.]
