Sir Thomas Musgrave, Marshal of Berwick
Sir Thomas Musgrave (1483-1532) was born at Hayton Castle, the son of Nicholas Musgrave and his wife, Margaret Colville-Tilliol. He married Elizabeth Dacre, daughter of Thomas Dacre, 2nd Baron Dacre of Gilsland and Elizabeth de Greystoke, and had nine children by her. He died on 23 February 1532, at Hayton; however an inquisition into his estate lasted until 1536. He became Constable of Bewcastle, a border castle and village near Carlisle, during a lawless period, when during raids by marauding Scots, such castles became sanctuaries. The 16th century saw tenancy by the Musgraves, who defended it against their sworn enemies, the Grahams and Armstrongs. Sir Thomas also received the appointment of Marshal of Berwick, a town with a strategic castle on the eastern coast of England, bordering with Scotland. The castle's location in the hotly disputed border region between England and Scotland made it one of the most important strongholds in the British Isles, and it enjoyed an eventful history. As a major tactical objective in the region, the castle was captured by both the English and Scots on a number of occasions and frequently sustained substantial damage.
