William Bruce, 8th Earl of Kincardine
William Bruce, 8th Earl of Kincardine  (died 8 September 1740), the son of Thomas Bruce, 7th Earl of Kincardine and Rachel Paunceforth, became the 8th Lord of Torry and the 8th Earl of Kincardine in 1740. His wife was Janet Roberton, the daughter of James Roberton, a Lord of Session (in turn a grandson of James Roberton, Lord Bedlay an ordinary Lord of Session during the Restoration.) and his wife Euphemia Burnett. The couple were second cousins, both descendants of Robert Bruce, Lord Broomhill. Bruce's descent was through his father Thomas Bruce 7th Earl of Kincardine and his grandfather Alexander 4th Earl of Kincardine. His wife's mother was the daughter of Janet Bruce, Alexander's sister. Bruce had five children:
