Saint Gilbert, founder of the Gilbertine Order

Saint Gilbert of Sempringham (c. 1083–1189) was an English priest born in Lincolnshire, the son of a Norman knight. After studying in France, he returned to England and became a parish priest, eventually founding the Gilbertine Order, the only religious order of medieval English origin. The order uniquely combined communities of nuns following the Cistercian rule with canons following the Augustinian rule, living in double monasteries. He governed the order for decades, overseeing its growth to numerous houses across England. He lived to a great age and was canonized by Pope Innocent III in 1202.
