Ingulf
Ingulph (or Ingulf) (died 16 November 1109) was a Benedictine abbot of Crowland, head of Crowland Abbey in Lincolnshire. He was an Englishman who, having travelled to England on diplomatic business as secretary of William, Duke of Normandy, in 1051, was made Abbot of Crowland in 1087 (Chambers and DNB say 1086) at Duke William's instigation after he had become king of England and the abbacy had fallen vacant. 1087 was in the last year of William's reign.
