William de Albini, feudal Lord of Belvoir, in the 6th of Richard I [1195], was with that monarch in the army in Normandy, and the next year was sheriff of the counties of Warwick and Leicester, as he was subsequently of Rutlandshire. In the 2nd of King John [1201], he had special license to make a park at Stoke, in Northampton, and liberty to hunt the fox and hare (it lying within the royal forest of Rockingham). Afterwards, however, he took up arms with the other barons and, leaving Belvoir well fortified, he assumed the governorship of Rochester Castle, which he held out for three months against the Royalists, and ultimately only surrendered when reduced to the last state of famine. Upon the surrender of Rochester, William Albini was sent prisoner to Corfe Castle, and there detained until his freedom became one of the conditions upon which Belvoir capitulated, and until he paid a ransom of 6,000 marks. In the reign of Henry III, we find him upon the other side and a principal commander at the battle of Lincoln, anno 1217, where his former associates sustained so signal a defeat. This stout baron, who had been one of the celebrated twenty-five appointed to enforce the observance of Magna Carta, m. 1st, Margery, dau. of Odonel de Umfraville, by whom he had had issue, William, Sir Odinel, Robert, and Nicholas, rector of Bottesford. He m. 2ndly, Agatha, dau. and co-heir of William Trusbut, and dying in 1236, was s. by his eldest son, William de Albini.
