The Musgrave family was a prominent Anglo-Scottish Border family with many descendants in the United States of America, Australia and the United Kingdom a so-called Riding or Reiver clan of Cumberland and Westmorland. The earliest record of the Musgraves is Gamel, Lord of Musgrave, noted as being "of the county of Westmorland and divers manors in county Cumberland, living in the time of King Edward the Confessor (1042-1065) predating the Norman Conquest." The Musgraves though often Wardens of the West March during the times of the Reivers and among the fourteen most notorious of the reiving clans were known locally as de’ils (devils) dozen and consisted of the following families: Armstrong, Bell, Carleton, Dacre, Elliot, Graham, Johnstone, Kerr, Maxwell, Musgrave, Nixon, Routledge,Storey and Scott.
