William of Peñacorada

Saint William of Peñacorada was a monk and hermit in northern Spain who died around 1042. He lived at the monastery of Sahagún in León. In 988, when the Saracens attacked, he fled with the other monks and settled at Peñacorada, where he built the monastery of Santa Maria de los Valles, later called San Guillermo de Peñacorada after him. He is a saint of the undivided Church, commemorated on 20 March (new style; 2 April in the old style).
