St. Vulsin, Bishop of Shireburn, Confessor
WILLIAM of Malmesbury informs us, that St. Dunstan, when bishop of London, appointed him abbot of twelve monks at Thorney, since called Westminster, where Saint Mellitus had built a church in honour of St. Peter. Vulsin was afterwards chosen bishop of Shireburn; his holy life was crowned with a happy death in 973. He is called Ultius by Matthew of Westminster; but his true ancient name, given by Capgrave, is Vulsin. See Malmesbury de Pontif. Angl. l. 2. Capgrave and Harpsfield, sæc. 10. c. 9. sæc. 11. c. 16.
