James Hamilton, 6th Earl of Abercorn

James Hamilton, 6th Earl of Abercorn, PC (Ire) was a Scottish and Irish peer and politician. Appointed a groom of the bedchamber to Charles II after the death of his father in battle, he took the Williamite side at the Glorious Revolution and on 21 March 1689 supplied Derry with stores that enabled the town to sustain the Siege of Derry until it was relieved in 1689. Shortly after inheriting a Scottish and Irish peerage from a second cousin, he was created a Viscount in Ireland for his services to the Williamite cause.
