Susan Montagu, Duchess of Manchester (2 February 1774 – 26 August 1828), formerly Lady Susan Gordon, was the wife of William Montagu, 5th Duke of Manchester.
[3] Susan married the Duke of Manchester in Edinburgh on 7 October 1793.
They had eight children:[4] The couple were estranged by 1808, when the duke became governor of Jamaica, and his wife remained in Britain.
[6] The duke was notoriously unfaithful,[7] but it was the duchess who became the subject of a scandal when she left him for a footman.
[8] An exile from polite society, the duchess died at Bedfont Lodge in Middlesex, in August 1828, at the age of 54.
