Input: Question: Who are the prominant Almack's? Passage:Lord Jersey married Lady Sarah Sophia Fane, daughter of John Fane, 10th Earl of Westmorland, on 23 May 1804. She was the eldest grandchild and heiress of Robert Child, principal shareholder of the banking firm Child & Co. Lord Jersey added the surname Child to the Villiers surname by royal licence in 1819. Lady Jersey was one of the great hostesses of English society, a leader of the ton during the Regency era and the reign of George IV, and a patroness of Almack's. Lord Jersey was an ardent fox hunter and a breeder and trainer of horses, owning two Epsom Derby winners, in Mameluke (1827) and Bay Middleton (1836) as well as other notable thoroughbreds such as Glencoe. His wife's numerous love affairs did not trouble him: asked why he had never fought a duel to protect her honour, he replied that he could hardly fight every man in London.
