Lady Elizabeth Hamilton was the eldest child of the 6th Duke and Elizabeth Gunning. Born 1753, she married Edward, 12th Duke of Derby in 1774 and they had a son Lord Stanley, and two daughters. She died in 1797.

James-George, born 1755, succeeded as 7th Duke in 1758. Following the death in 1761 of the Duke of Douglas he was at the heart of a long lawsuit (the 'Douglas Cause') over the right to the Douglas estates, eventually decided against him in 1769.

In the same year, having outgrown his strength, the 14 year old duke died at the Palace of Hamilton, his epitaph there written by his tutor Dr John Moore. He was succeeded by his younger brother Douglas, who died without issue in 1799.
