The manuscript history of the founders of Gysburne/Gisborough Priory records that “Adam de Bruse secundus filius et hæres Adæ patris sui” succeeded his father, died “1180 V Id Jul” [sic] ... and was buried “apud Gysburghe”.
He succeeded his father as Lord of Skelton. He was of age in 1155. “A. de Brus” donated property to the canons of Gysburne/Gisborough, for the souls of “R. de Brus avi mei et A. patris mei”, by charter dated to [1155/65], witnessed by “Petro de Brus…”. The Pipe Roll 1161/62 records "Adam de Brus" in Carlisle. The 1170/71 Pipe Roll records "Ada de Brus" accounting for ".c. li. p hedibus Robt de Pci qs habuit I custod sua p habenda tra Ærnaldi auunculi eorum" in Yorkshire. Brown states that Adam [II] de Brus was recorded in [1196/97] as owing the king £20 being part of the debts of Aaron the Jew in Yorkshire.
The obituary of Gysburne/Gisborough priory records the death “XIII Kal Apr” of "Adæ de Brus Scdi". It should be noted that "XIII Kal Apr" is the date of death attributed to Adam [I] de Brus in the manuscript history of Gysburne/Gisborough Priory. It is not known whether the obituary, or the manuscript history, reproduces the correct dates of death of Adam [I] and Adam [II]. 1
