As a beauty, Harriet attracted many young suitors and admirers—not just Granville. One of her younger admirers, William Lamb, for example, was hungry for some Harriet, that is, until he met and fell in love with Harriet’s daughter, Caroline.

A prolific writer of letters, Harriet corresponded with others for most of her life, often humorously describing her observations of those around her. Historians have since found her detailed accounts to be a valuable source of information on life as an ambassadress as well as life in the 19th-century aristocracy. Between 1894 and 1990, four edited collections of Harriet's correspondence were published.

Lady Georgiana Howard (1804 – 17 March 1860) she married George Agar-Ellis, 1st Baron Dover on 7 March 1822. They have four children.

Some Old Time Beauties by Thomson Willing Featuring a different version of her picture as well as written material on her reputation.Henrietta Elizabeth "Harriet" Leveson-Gower, Countess Granville ( née Cavendish; 29 August 1785 – 25 November 1862) was a British peeress and society hostess. She was born in Devonshire House as the second daughter of William Cavendish, 5th Duke of Devonshire by his wife, the political hostess Lady Georgiana Spencer. Despite her parents' turbulent marriage, Harriet had a happy childhood. Her mother's death in 1806 led to an unpleasant situation in which her father's long-time mistress Lady Elizabeth Foster took control of the Devonshire household; as the unmarried eldest daughter, this should have been Harriet's role. Contents She was called a "phenomenon" [7] by Horace Walpole who proclaimed, "[she] effaces all without being a beauty; but her youthful figure, flowing good nature, sense and lively modesty, and modest familiarity make her a phenomenon". [21] Madame d'Arblay, who had a preference for acquaintances of talent, found that her appeal was not generally for her beauty but for far more, which included her fine "manner, politeness, and gentle quiet." [21] Sir Nathaniel Wraxall stated that her success as an individual lay "in the amenity and graces of her deportment, in her irresistible manners, and the seduction of her society."

Each gap was due to a change of government leadership, when a transition of political party prompted Granville to resign his post in 1828 and then in 1834. [45] [110] They typically returned to England during each interval. [45] [111] In 1833 their second son William, who may have suffered from a chronic condition, died at the age of seventeen; he is rarely mentioned in his mother's letters. [112] [113] In 1841 Granville suffered a severe stroke which caused partial paralysis, and he resigned his ambassadorial post a few months later. For the next two years the family travelled across Europe, before returning to England in November 1843. [45] [114] They resided in houses in Brighton and London, and spent portions of their time visiting friends and family at their various country estates. [45] [115] Granville suffered another stroke in October 1845 and died in January of the following year.
