WARWICK, EARLS OF. The 1st earl of Warwick was HENRY DE NEWBURGH (d. 1123), lord of Newbourg in Nor mandy and son of Roger de Beaumont. He became constable of Warwick castle in 1°68, and, though there is no proof that he actually came over with the Conqueror, his elder brother Robert de Beaumont, comte de Meulan, fought at Hastings. He ap parently spent most of his time in Normandy, and was a baron of the Norman exchequer. He was created earl of Warwick early in the reign of William II. receiving a grant of the great estates of the Saxon, Thurkill of Arden, in Warwickshire. He founded the priory of the Austin Canons, and endowed the church of St. Mary. The 6th earl, THOMAS DE NEWBURGH (c. I2I3– 1297), left no heirs, and was succeeded by his sister Margaret, countess of Warwick in her own right, who was twice married, but left no heirs. Her second husband, John du Plessis, assumed the title of earl of Warwick in 1245, and in 1250 received a grant of his wife's lands for life. He was succeeded in 1263 by Countess
Margaret's cousin and heir, SIR WILLIAM MAUDUIT ( 1 2 268) , 8th earl of Warwick.
The Beauchamps.-Mauduit's sister and heiress, Isabel de Beauchamp, had apparently adopted the religious life at the time of her brother's death, and her son WILLIAM DE BEAUCHAMP became 9th earl of Warwick.
His son GUY DE BEAUCHAMP, I Oth earl of Warwick (1278 1315), received grants of land in Scotland for his services at Falkirk, and in 1301 was one of the signatories of the letter to the pope denying the papal right to interfere in Scottish affairs. He was one of the lords ordainers of 1310, and was concerned in the capture of Gaveston, though he declined to countenance his execution. He died on Aug. to, 1315. His son, THOMAS DE BEAUCHAMP, I earl (1313-1369), marshal of England in and of the English army in France in 1346, fought at Crecy and Poitiers, and was one of the original knights of the Garter.
