Sarah Fane, Countess of Jersey

Sarah Child Villiers, Countess of Jersey (nee Lady Sarah Fane; 1785-1867), called Silence, was the daughter of John Fane, 10th Earl of Westmorland, and his wife Sarah Child. Her grandfather Robert Child (of Child & Co.) left his entire fortune to her. She married George Child Villiers, 5th Earl of Jersey, on 23 May 1804. He took her grandfather's surname as part of his own. Together they had seven children (of whom she outlived six as well as her husband).

Though she was not an infamous as her mother-in-law Frances Villiers, she had many affairs herself, and one of her lovers might have been Henry John Temple, 3rd Viscount Palmerston, lover and future husband of her fellow Almack's patroness Emily Cowper.
