“Robertus de Brus” donated property to St Mary’s, York by charter dated to [1125/35], witnessed by “Ada filio meo, Petro de Brus…”. “Robertus de Brus…Agnes uxor mea, filiusque noster Adam de Brus” donated property to Middlesburgh priory by undated charter.
“Robertus de Brus…et Agnes uxor mea et Adam filius noster” founded Gysburne/Gisborough Priory, Yorkshire by undated charter.
He succeeded his father in 1141 as Lord of Skelton.
The manuscript history of the founders of Gysburne/Gisborough Priory records that “Adam de Bruse filius et hæres…Roberti patris sui” succeeded his father in 1141, died “1167 XIII Kal Apr…anno regni regis Henrici secundi…octavo” and was buried “apud Gysburghe”. The year and the regnal year (indicating [1160/61]) in this passage are inconsistent. Assuming that it is correct that Adam’s widow married William de Roumare as her second husband... both these years must be incorrect and Adam [I] must have died in [1142/43], although the primary source (if any) which confirms that this date is correct has not yet been identified. This speculation all appears to be confirmed by the Chronicle of John Prior of Hexham which records the death of "Adam de Brus" in 1143. It should be noted that the obituary of Gysburne/Gisborough priory records the death “XIII Kal Apr” of "Adæ de Brus Scdi". It is not known whether the obituary, or the manuscript history, reproduces the correct dates of death of Adam [I] and Adam [II]. 1
