John de Gray [SEP] Introduction
John de Gray or de Grey (died 18 October 1214) was an English prelate who served as Bishop of Norwich, and was elected but unconfirmed Archbishop of Canterbury. He was employed in the service of Prince John even before John became king, for which he was rewarded with a number of ecclesiastical offices, culminating in his "pro forma" election to Norwich in 1200. De Gray continued in royal service after his elevation to the episcopate, lending the King money and undertaking diplomatic missions on his behalf. In 1205 King John attempted to further reward de Gray with a translation to the archbishopric of Canterbury, but a disputed election process led to de Gray's selection being quashed by Pope Innocent III in 1206.
