David Lindesay-Bethune, 15th Earl of Lindsay (9 February 1926 – 1 October 1989), styled Viscount Garnock between 1943 and 1985, was a British soldier.
Lindsay was the son of William Tucker Lindesay-Bethune, 14th Earl of Lindsay and Marjory Cross, daughter of Arthur John Graham Cross. He was educated at Eton and Magdalene College, Cambridge.[1] He served in the Scots Guards as a junior officer and left with the rank of Major in 1951.[2]
He was appointed Honorary Colonel on 29 May 1957[3] of the Fife and Forfar Yeomanry/Scottish Horse. He held this post until 1962, when his tenure expired. He was however allowed to retain the honorary rank of Colonel.[4]
