In or about the year 1084 Thomas I, Archbishop of York, acting evidently in request to Ulured, Provost of Hexham (1056–1085), and Eilaf I, Priest of Hexham (1050–1086), to exercise his lordship over the desolate district of Hexham, constituted the Spiritual rights of the regality a part of the endowment of the prebendal stall of Holme in the Cathedral of York, and gave the stall to a canon of Beverley, named Richard de Maton — who thus became Rector of Hexham, and under whom Eilaf I, and his successor Eilaf II, occupied a subordinate position as Priest of Hexham.
Richard de Maton — Canon of Beverley in 1084; Prebendary of Holme in York Cathedral 1084–1114; Rector of Hexham 1084–1114; Prebendary of Salton in York Cathedral 1114; Canon residentiary of York 1114. He died a monk at Durham, 15th December, 1138, and was buried in the Conventual Cemetery there. He was the last of the hereditary priests of Hexham.
