 Bishops were forced to intervene three times in the 15th century in 1442, 1452 and 1485 to appoint a prioress because of prolonged vacancies, although the nuns were supposed to elect their own head.However, the visitation of 1521 found the priory in good order, although one nun commented that young girls slept in the dormitory with the nuns.The following list is based on that in the Victoria County History, with additions from other referenced sources.
