John Fitz-Robert, to whom King John in the 14th year of his reign [1213], ratified the grant of the castle and manor of Warkworth, made by King Henry II to his grandfather, Roger Fitz-Richard, as also of the manor of Clavering. In three years afterwards, he was appointed joint governor with John Marshall of the castles of Norwich and Oxford; but joining in the insurrection of the barons, and being chosen one of the twenty-five appointed to exercise the regal authority, his lands were seized by the king and a part confiscated. Returning, however, to his allegiance in the next reign, his castles and estates were restored to him. In the 9th of Henry III [1225], he was constituted sheriff of Northumberland and governor of the town of Newcastle-upon-Tyne; and in the 13th of the same monarch [1329], he was one of the great northern barons appointed by special command of the king to wait upon Alexander, King of Scotland, at Berwick-upon-Tweed, and to conduct that prince to York, there to meet the king of England, "to treat upon certain affairs of great importance." His lordship m. Ada, dau. and heir of Hugh de Baliol, and grand-aunt of Baliol, King of Scotland, and had issue, Roger, his successor; Hugh, surnamed "de Eure," from whom the Lords Eure descended; and Robert, ancestor of the Eures of Axholm, in Lincolnshire. He d. in 1240, and was s. by his eldest son, Roger Fitz-John. [Sir Bernard Burke, Dormant and Extinct Peerages, Burke's Peerage, Ltd., London, 1883, p. 121, Clavering, Barons Clavering]
