Manners never married, but by his mistress Corbetta Smyth, daughter of William Smyth, Apothecary of Shrewsbury, he had ten children: • Corbetta Manners (1728–before 1753), eloped to marry Capt. George Lawson Hall; their daughter Corbetta Hall was a chief beneficiary of her grandmother's will. •
John Manners (1730 – 23 September 1792) politician, married
Louisa Tollemache, 7th Countess of Dysart and had issue, several children. • Rev. Thomas Manners (1731 – 1 December 1812), twice married; firstly in 1758 to Susannah Buckland, who suffered from a mental condition, and secondly immediately after her death. His son William Manners married Frances Whichcote of Aswarby, and has descendants. • William Manners (1734–1827), married Caroline Pickering •
Russell Manners (1736–1800), married Mary Rayner • Augusta Manners (21 November 1737 – 1828) • Frances Manners (1739–1817) • Robert Manners (b. 1740), died young • Caroline Manners (1741–1800), married Jeremiah Ellis • Robert Manners (2 May 1743 – 18 April 1810), married Elizabeth White (1749–1817)With numerous descendants including Rear Admiral Sir
Errol Manners (1883-1953). His descendant David Drew-Smythe speculates that Lord William Manners and his mistress Corbetta Smyth, who had a long-term relationship, never married because of inheritance clauses. All Corbetta's children were recognized by their father. Conditions of inheritance being linked to stipulations about specific marriage expectations or restrictions are not uncommon and have been known to "force" couples into living and bringing up their children in 'unmarried' relationships in order to avoid losing an inheritance. This is speculation, of course, but there must have been some specific reason why they chose to be unmarried. ==Notes==
