John I

John (fl. 1043 x 1072) was an 11th-century prelate. According to the Saxon writer Adam of Bremen, historian of the archbishops of Hamburg, John was sent to Orkney by Adalbert, Archbishop of Hamburg, to succeed Thorulf as Bishop of Orkney. According to Adam, he had previously been consecrated as a bishop in "Scotland" (either Britain north of the Firth of Forth or Ireland).
