[2] The first prior of St Osyth's was William de Corbeil, who was elected archbishop of Canterbury in 1123 and who crowned King Stephen in 1135.

[4] In the Gesta Pontificum Anglorum, William of Malmesbury spoke in praise of the piety and learning of the canons at St Osyth's in the twelfth century.

[5] One of the second generation of canons there was William de Vere, later bishop of Hereford, who wrote a Latin Life of St Osyth,[6] in which he mentions that his mother Adeliza, daughter of Gilbert fitz Richard of Clare, had been a corrodian at the abbey for twenty years of her widowhood.

A charter of King Henry II confirmed the right of the canons of St Osyth's to elect their abbot and to hold a market every Sunday at Chich in the later 12th century.

[7] During the Suppression of the Monasteries, the religious group was dissolved by King Henry VIII in 1539, at which time there were a prior and sixteen canons.
