. William de Cantilupe, the first of this family on record, served the office of Sheriff for the counties of Warwick and Leicester in the 3rd, 4th, and 5th years of the reign of King John. In the next year he was made Governor of the castles of Hereford and Wilton, and he was subsequently Sheriff of Herefordshire. In the 11th year of the same reign, being then the king's steward, he gave 40 marks for the wardship of Egidia, Lady of Kilpeck, widow of William Fitz-Warine, and in three years afterwards, when the king was excommunicated by Pope Innocent III., he remained so faithful as to become one of the king's chief counselors. Later he was arrayed under the baronial banner, and joining in the invitation of Kong Louis of France. But within the same year he returned to the king, when he obtained grants of all the forfeited lands of Richard de Engaine and Vitalis de Engaine, two leading barons in the insurrection; and was appointed Governor of Kenilworth Castle, co. Warwick. In the reign of King Henry III. he continued attached to the cause of royalty, and acquired immense possessions in the shape of grants from the crown of forfeited lands.
