(Isle of Wight) is recorded as a martyr on 21 March 1211 in MS. Gonville and Caius, Cambridge, 111/205. This is confirmed by the Waverley Annals for the same year, which adds that miracles take place at his tomb very frequently. Recent research has shown that he was killed, not by French invaders, but by his own wife, Amicia Norri, daughter of Hugh le Norays, tenant of the bishop of Winchester. She was burnt at the stake, like other homicides at Portsmouth and elsewhere, after being found guilty of ‘petty treason’. Offerings at Simon's tomb amounted to £7 in 1211, but his local cult soon died or was suppressed by the bishop of Winchester.
