Kettlethorpe Hall is a Victorian house in Kettlethorpe, Lincolnshire, noted for its connection to Katherine Swynford. It encloses fragments of the former manor house including the gatehouse, within the surviving moat. This moat and its cleaning was one of the egregious examples of MPs' expenses claims which aroused public ire during 2009. This contributed to the retirement of its owner, Douglas Hogg, from the House of Commons.
Sir Hugh Swynford (died in 1371) married Katherine Roelt, whose sister is believed to have been the wife of Geoffrey Chaucer. Lady Katherine became governess to the children of John of Gaunt, the third surviving son of Edward III. Her four children by Gaunt, the Beauforts, were eventually legitimized when Lady Katherine married John of Gaunt as his third wife, in 1396. She at one time lived at Kettlethorpe Hall.
