George Mackenzie, 3rd Earl of Cromarty (c. 1703–28 September 1766) succeeded his father John, the 2nd earl, in February 1731. In 1745, he joined Charles Edward Stuart and he served with the Jacobites until April 1746 when he was taken prisoner in Sutherland after the Battle of Littleferry. He was tried and sentenced to death, but he obtained a conditional pardon although his peerage was forfeited, allegedly because his wife was heavily pregnant. He was however reduced to extreme poverty, because the family estates and rights were confiscated in 1748. He died on 28 September 1766 in Soho Square, London, having never gone north of the River Trent again, in keeping with the terms of his pardon.

He married Isabel Gordon, daughter of Sir William Gordon of Invergordon, on 23 September 1724 and had a large family of young children. Isabel Gordon also went by the nick-name of 'Bonnie Bell' Gordon.
