He was appointed Justice in Eyre south of the Trent along with Peter Atte Wode in 1361, a position he held until about 1367. William was ordained in 1362 and paid for his services by being given the incomes of various churches. For instance, in April 1363, Edward III presented him to the archdeaconry of Lincoln, a move that was approved by Pope Urban V in November 1363 only after representations from Sir Nicholas de Loveyne, the king's ambassador to the papal court.[2] By 1366, William held two benefices and eleven prebends, with an annual income exceeding £800.
