Jun 8 William of York an English priest and Archbishop of York. William has the unusual distinction of having been Archbishop of York twice, both before and after his rival Henry Murdac. He was a relative of King Stephen of England, and the king helped secure FitzHerbert's election to York after a number of candidates had failed to secure papal confirmation. William faced opposition from the Cistercians who, after the election of the Cistercian Pope Eugene III, managed to have the archbishop deposed in favour of the Cistercian Murdac. From 1147 until 1153, William worked to secure his restoration to York, which he finally achieved after the deaths of both Murdac and Eugene III. He did not retain the see long, as he died shortly after returning to York, allegedly having been poisoned. After William's death miracles were reported at his tomb from the year 1177 onwards, and in the year 1227 he was declared a saint
