“ SHEPPEY, JOHN de (d. 1360) , bishop of Rochester, was a native of Kent, and, being educated under the patronage of Haymo Heath, bishop of Rochester, became a Benedictine monk at that city, and was sent to complete his education at Oxford. At the university Sheppey acquired a great reputation, and graduated as doctor of divinity. In 1333 the convent of Christ Church, Canterbury, applied for his interest on behalf of one of their monks studying at Oxford (Litteræ Cantuarienses, ii. 27) . In March 1333 Sheppey was elected prior of Rochester (Wharton, Anglia Sacra, i. 371) . ”
