¹ The V.C.H. list includes Elias of Derham among the priors of this house, occurring in 1225, but he had left Canterbury by about 1220/2. He was connected with many architectural works, including the shrine of St. Thomas Becket, and by 1220 he is called a canon of Salisbury by Matthew Paris. From this time on he assisted in many building works there, and was later Master of the King's Works at Windsor. He witnesses various deeds in this cartulary, for, besides being one of Archbishop Stephen Langton's familia, he returned to Canterbury to supervise some building for Archbishop Edmund Rich, and some of the deeds date from this later period. The only evidence for his priorate at St. Gregory's is a single charter (Combwell Charters, College of Arms Box 24A) which has his name among the witnesses together with the title of prior of St. Gregory's, but a consideration of his career makes it certain that this was a scribal error, omitting the name or initial of the prior of the time.
