[1] She was a daughter of William Gordon, 2nd Earl of Aberdeen, and his second wife, the former Lady Susan Murray.
Her paternal grandparents were George Gordon, 1st Earl of Aberdeen, and his wife Anne Lockhart.
[9] In 1754, Horace Walpole described the duchess as looking "like a raw-boned Scottish metaphysician that has got a red face by drinking water", and implied that she had made advances to Stanisław August Poniatowski (the future King of Poland).
[10] In March 1756, the widowed duchess married Staats Long Morris, an American soldier who had become a British MP.
Morris became MP for Elgin Burghs in 1774, largely due to the influence of his stepson, the new Duke of Gordon.
