Henrietta Stanhope, Countess of Chesterfield

She married the earl on 2 May 1799, in Grosvenor Street, London.^[2] From his first marriage to Anne, who died in 1798, he had one daughter, Lady Harriet Stanhope, who died unmarried in 1803. They resided at the family seat, Bretby Hall in Derbyshire, which was rebuilt by the earl in about 1812. The couple had two children:

• Lady Georgiana Stanhope (d. 1824), who married Frederick Richard West, a grandson of John West, 2nd Earl De La Warr.
• George Stanhope, 6th Earl of Chesterfield (1805–1866), who married Hon. Anne Elizabeth Weld-Forester, a daughter of Cecil Weld-Forester, 1st Baron Forester and Lady Katherine Manners (a daughter of the 4th Duke of Rutland).

The countess was a Lady of the Bedchamber to Charlotte of Mecklenburg-Strelitz, queen consort of King George III of the United Kingdom, from 1807 until her own death in 1813.^[3]

The countess died at the family's London home, Chesterfield House, Mayfair, aged 50 (though contemporary death notices describe her as 52).^[4] Her husband survived her by two years and died aged 59. He was succeeded in the earldom by their son, George.^[5]
