Thomas Finlayson Henderson, Dictionary of National Biography… (1893)
“ He became an excellent classical scholar, and cultivated both literature and science, but politics absorbed his chief interests. In 1663 he joined Glencairn's expedition on behalf of Charles II, and on the defeat of Middleton [see Middleton, John, first Earl of Middleton] , 26 July 1654, fled to the castle of Island Donan. He succeeded to the family estates on his father's death, 10 Sept. ”
