- Sir John Christopher Foggo Montgomery Cuninghame of Corsehill, 12th Baronet of Corsehill (born 24 July 1935). Montgomery Cuninghame (following a ruling by Lord Lyon in 1996 he de-hyphenated the surname in order not to be denied recognition as family head) is a British businessman. He is the second son of Sir Thomas Montgomery-Cuninghame, 10th Baronet, and his second wife, Nancy née Foggo. He was educated at Fettes College and Worcester College, Oxford Before university he was commissioned as a National Service officer into The Rifle Brigade. On 9 September 1964, he married Laura Nicholson, the second daughter of Sir Godfrey Nicholson, Bt. and they have three daughters: Christian Elizabeth (born 1967); Georgiana Rose "Nina" (born 1969), married ITV's journalist, Rageh Omaar; Elizabeth Clara (born 1971), married to Ben Brabyn. Sir John Cuninghame has had wide experience as an investment banker and venture capitalist both in North America and in Europe. He began his career in a large investment bank in Canada, he has set up an investment bank in Switzerland and was a director of Morgan Grenfell & Co in London. Since then he has been an active director of a number of companies and trusts, both in the UK and the United States.His involvement in venture capital has included Inertia Dynamics which was floated on the market, before being bought by Ryobi of Japan. He also served on the advisory board of Bedford Capital Corporation which operated in the private equity market in North America.
Sir John claims the title of Earl of Glencairn although he has never officially petitioned the House of Lords and his ancestors did not petition for the title in the House of Lords in 1797 as they had not provided sufficient evidence of being heirs-male to the Earls of Glencairn and again denied in the 19th century due to a lack of propinquity. The estates and lordships were passed by strict entail of the 12th Earl of Glencairn to the "heirs male of her own body" of his eldest daughter, Lady Margaret Cunningham, wife of Nicol Graham of Gartmore and to their line should his male heir line fail, which it did upon the death of the 15th Earl of Glencairn in 1796.
Sir John petitioned the Lord Lyon, King of Arms, for recognition as Chief of the Name and Arms of Cunningham in March 2010 and was recognised as such by the Lyon´s interlocutor of 18 December 2013 as Cunninghame of that Ilk. He is, therefore, the first Chief of the House of Cunninghame in over 200 years.
There is no heir to the baronetcy of Corsehill, though his chiefship may pass to and through the female line.
