Mary Godolphin was born 23 November 1723 to Francis Godolphin, 2nd Earl of Godolphin (1678-1766) and Henrietta Churchill, 2nd Duchess of Marlborough (1681-1733) and died 3 August 1764 of unspecified causes. She married Thomas Osborne, 4th Duke of Leeds (1713-1789) 26 June 1740 .
Lady Mary was considered to be the illegitimate child of the famous playwright William Congreve, with whom Henrietta, Duchess of Marlborough, was having a long-term relationship. She was, however, recognised by Francis as his own daughter, and was raised by him with the other Godolphin children. Despite this, gossip spread rapidly about Lady Mary's paternity, and her maternal grandmother did not recognise her until 1740, when the two reconciled their differences. [Wikipedia]
