Elizabeth Cavendish, Duchess of Devonshire(Redirected from Bess Foster)
Elizabeth Christiana Cavendish, Duchess of Devonshire (13 May 1758 – 30 March 1824) was an English novelist and duchess. She is best known as Lady Elizabeth Foster, the close friend of Georgiana Cavendish, Duchess of Devonshire. Elizabeth supplanted the Duchess, gaining the affections of William Cavendish, 5th Duke of Devonshire, and later marrying him.

In 1776, Elizabeth married Irishman John Thomas Foster (1747–1796). He was a first cousin of the brothers John Foster, last Speaker of the (united) Irish House of Commons, and Bishop (William) Foster. The Fosters had two sons, Frederick (3 October 1777 – 1853) and Augustus John Foster (1780 – 1848). Their only daughter, also named Elizabeth, was born prematurely on 17 November 1778 and lived only eight days.
When her father succeeded as the earl in 1779, she became Lady Elizabeth Foster. The couple resided after 1779 with her parents at Ickworth House in Suffolk. The marriage was not a success, and the couple separated within five years, plausibly after Foster had a relationship with a servant. Foster retained custody of their sons and did not allow the boys to see Bess for 14 years.
In May 1782, Bess met the Duke and Duchess of Devonshire in Bath, and quickly became Georgiana's closest friend. From this time, she lived in a triad with Georgiana and her husband, William, the 5th Duke of Devonshire, for about 25 years. She bore two illegitimate children by the Duke: a daughter, Caroline St Jules, and a son, Augustus (later Augustus Clifford, 1st Baronet), who were raised at Devonshire House with the Duke's legitimate children by Georgiana. Georgiana grew ill and died in 1806; three years later, Bess married the duke and became the Duchess of Devonshire. He died two years later.
Bess is also said to have had affairs with several other men, including Cardinal Ercole Consalvi, John Sackville, 3rd Duke of Dorset, Count Axel von Fersen, Charles Lennox, 3rd Duke of Richmond, and Valentine Quin, 1st Earl of Dunraven and Mount-Earl. There is some evidence that Quin fathered an illegitimate son by her, who became the noted physician Frederic Hervey Foster Quin. Quin joined the Duchess as her travelling physician in Rome in December 1820, and afterwards attended her in that city during her fatal illness in March 1824.
