By 1155 or 1156 the d'Ivry estates had passed to John de St. John of Stanton St. John and Reynold de St. Valery. Reynold died leaving the estates to his son Bernard, who in turn died leaving them Reynold's younger son Thomas. Thomas supported Philip II of France in his wars against England, so by 1196 or 1197 Richard I seized the de St. Valery estates including Beckley. During the 13th century Thomas de St. Valery and his heir by marriage, Robert de Dreux, changed sides a number of times between England and France. They forfeited and regained their English estates a number of times as a result.
