David Erskine, 9th Earl of Buchan, 4th Lord Cardross, PC (3 January 1672 – 14 October 1745) was a Scottish peer. He was the son of Henry Erskine, 3rd Lord Cardross, by Catherine, daughter of Sir James Stewart of Kirkhill. He was styled Master of Cardross and then Lord Cardross until 1695 whereupon he claimed Earldom of Buchan.[1]
Although a kinsman of the Earl of Mar, a prominent Jacobite statesman, Buchan was a supporter of the Hanoverian cause during the various Jacobite risings. He joined the Duke of Argyll during the suppression of the 1715 rising.[2] After the aforementioned rising, he sat in the House of Lords as a Scottish representative peer between 1715 and 1734.[2]
