WILLIAM de WARENNE was considered a near kinsman of William the Conqueror. He received large grants of land in England in recognition of his distinguished part in the Battle of Hastings. In 1075, he was appointed joint chief justiciar and helped suppress the rebellion of the earls of Hereford and Norfolk. In 1077 he founded the St. Pancras Priory of Lewes (where he is buried), the first house of the Cluniac order in England. The position of his castle at Lewes rendered his loyalty especially useful to King William Rufus during the rebellion of 1088, for which he was granted the earldom of Surrey. In addition to Lewes, William held over 40 manors in Sussex. He married Gundred and had Reginald, Edith, and William
