George Augustus Cavendish was born in London, the second son of William Cavendish, 3rd Duke of Devonshire. He was educated in Chesterfield and at St John's College, Cambridge.[1]
In 1753, he inherited Holker Hall from his cousin Sir William Lowther, 3rd Baronet. He replanted the park there, and added a number of unusual trees.
He entered Parliament in 1751 for Weymouth and Melcombe Regis, and in 1754, took up the family seat of Derbyshire, which he occupied, with one interruption, until his death forty years later.
