Charlotte Cavendish, Marchioness of Hartington Wikipedia
Charlotte Elizabeth Cavendish, Marchioness of Hartington, 6th Baroness Clifford (née Boyle; 27 October 1731 – 8 December 1754) was the daughter of Richard Boyle, 3rd Earl of Burlington and Lady Dorothy Savile. From 1748 until her death she was married to William Cavendish, Marquess of Hartington, later the 4th Duke of Devonshire and Prime Minister of Great Britain.
Lady Charlotte Elizabeth Boyle was the only surviving daughter of Richard Boyle, 3rd Earl of Burlington and Lady Dorothy Savile. Her mother was the daughter of William Savile, 2nd Marquess of Halifax.
On 28 March 1748, she married William Cavendish, then the Marquess of Hartington, who later became the 4th Duke of Devonshire and the Prime Minister of Great Britain. The advantageous union had been arranged since childhood and was happy. The marriage helped him rise politically. They had four children: William, Dorothy, Richard, and George.
Charlotte inherited great wealth upon the death of her father in 1754. Lady Clifford gained the title of Baroness Clifford suo jure. Through her marriage, the Cavendish family, with the main title Duke of Devonshire, inherited the 3rd Earl of Burlington's estates (the title went through to the Orrery Boyles). These estates include Burlington House, Piccadilly, London (now the Royal Academy of Arts); Chiswick House, London W4; Londesborough Hall, Yorkshire; Bolton Abbey, Yorkshire; Lismore Castle, County Waterford, Ireland. She was his sole remaining heir.
