Henry of Poitiers

Henry of Poitou – not to be confused with Henry of Antioch who was also known as Henry of Poitou – thought to be the son of William VII of Poitou. Henry was an ecclesiastic, and, according to the Peterborough Chronicle, held a number of titles throughout his career. He was a sworn witness attesting to the consanguinity of William Clito and Sybilla of Anjou, which led to the annulment of their marriage in 1124 by Pope Calixtus II.
