Saint William of York, born around the year 1110, was the son of Count Herbert, treasurer to Henry I. He was elected archbishop of York in 1140. William's election was challenged on the grounds of simony and unchastity. He was cleared by Rome, but later a new Pope suspended William, and in 1147 he was deposed as archbishop of York. William then retired to Winchester where he led the austere life of a monk, practicing much prayer and mortification. Upon the death of his accusers, Pope Anastastius IV restored William his See and made him archbishop. William died in the year 1154.
