Langdon Abbey was founded in about 1192 by William de Auberville (the elder) of
Westenhanger, Kent (son of Hugh de Auberville), with the assent of his wife Matilda (Maud), daughter of
Ranulf de Glanville (who died at the
Siege of Acre in 1190),
Chief Justiciar of England to
King Henry II. William de Auberville was a knight in duty to Simon de Avranches. He was also a
King's Justiciar, had assisted at the foundation of the Premonstratensian abbey of
Leiston, Suffolk, by his father-in-law in 1182, and was a patron of Ranulf's religious foundation at
Butley Priory, Suffolk, of 1171. Langdon Abbey was founded as a
daughter house of Leiston Abbey, under the hand of Robert, abbot of Leiston, and was dedicated to the
Blessed Virgin Mary and
St Thomas the Martyr. Sir William annexed the
church of St. Mary in
Walmer to the abbey, in perpetual alms, and the church remained with the abbey until its dissolution. Patronage of Langdon descended to Nicholas de Crioll (the younger), son of William's great-granddaughter Joan de Auberville and her husband
Nicholas de Crioll (the elder). ==Royal favour==
