The manuscript history of the Bruce family of Carleton records that “primus Brus de Carleton…Robertus de Brus” married “Agnetam filiam Fulconis Paynell” and received “manerium de Carleton” from his father-in-law. The primary source which confirms that Agnes’s father was Fulk Paynell of Staffordshire has not yet been identified. “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 Gisburne Priory, Yorkshire by undated charter. The 1155 Pipe Roll records "Agnes de Bruis…p filio suo". A charter of King Henry II, dated to [1176/86], confirmed donations to the canons of Gisburne, among which a donation by “Agnetis uxoris Roberti de Brus”.
The obituary of Gisburne priory records the death “XIV Kal Dec” of "Agnetis Brus uxoris fundatoris nostri". 1
