William de Beauchamp inherited not only the feudal barony of Elmley from his father, but had previously derived from his mother the Earldom of Warwick (originally possessed by the Newburgh's) and also the barony of Hanslape, which had belonged to the de Maudits. This eminent nobleman was a distinguished captain in the Welsh and Scottish Wars of Edward I. "In the 23rd year of which reign (1294/5), being in Wales with the king," as Dugdale relates, "he performed a noble exploit, namely: Hearing that a great body of the Welsh were got together in a plain, betwixt two woods, and to secure themselves had fastened their pikes to the ground, sloping toward their assailants, he marched thither with a choice company of cross-bowman and archers, and in the nighttime encompassing them about, put betwixt every 2 horseman, one crossbowman, which cross-bowman killing many of them that held the pikes, the horse charged in suddenly and made a very great slaughter." This was done near Montgomery. His lordship married Maud, widow of Girard de Furnival, and one of the four daughters and co-heiresses of Richard FitzJohn, son of John FitzGeoffrey, Chief Justice of Ireland, by whom he had surviving issue: Guy, his successor, Isabel, who married Peter de Chaworth (from whom you descend in several ways. E. E. W.), Maud, Margaret, Ann and Amy. William de Beauchamp, first Earl of Warwick of that family, died 1298, having previous to his mother's death used the style and title of Earl of Warwick, with what legality appears very doubtful.

Walter de Beauchamp became Baron of Alcester in Warwickshire and Powyck in Worcestershire. He purchased from Reginald FitzHerbert a moiety of the Manor of Alcester and made that one of his principal seats, calling it Beauchamp's Court, Powyck being the other. This Walter, who was a very eminent person at the period in which he lived, being signed with the cross for a pilgrimage to the Holy Land, had a legacy of 200 marks bequeathed him by his father for the better performance of that voyage. He was Steward of the household of King Edward I and attended that monarch to Flanders and into Scotland, where he shared in the honors of Falkirk on 22 July, 1298. In the 29th of the same reign he was one of the lords in Parliament of Lincoln, being styled Dominus de Alcester, who signified to the Pope, under their seals, the superiority of King Edward over the Kingdom of Scotland. His lordship married Alice de Toney and had issue three sons: Walter, who succeeded his father and died sine prole, and was succeeded by his brother William, who also died without issue, and the estates devolved upon the other brother,
