The murder of Sir William de Cantilupe, who was born around 1345, by members of his household, took place in Scotton, Lincolnshire, in March 1375. The family was a long-established and influential one in the county; de Cantilupes traditionally provided officials to the Crown both in central government and at the local level. Among William de Cantilupe's ancestors were royal councillors, bodyguards and, distantly, Saint Thomas de Cantilupe.
