John Hay of Cromlix

John Hay of Cromlix (1691–1740) was the Jacobite Duke of Inverness and a courtier and army officer to the King James VIII & III (known as the "Old Pretender"). He was from the Clan Hay.

His parents were Thomas Hay, seventh earl of Kinnoull (c.1660–1719) and Elizabeth (1669–1696). He was their third son, with their first son, George (d. 1758), succeeding their father. The family was sympathetic to the Stuart kings but still felt that being Protestant and serving Queen Anne and supporting the Harley administration did not mar this sympathy and loyalty.

John's maternal grandfather William Drummond, first viscount of Strathallan, bequeathed Thomas an estate at Cromlix, Perthshire. Thomas purchased a commission in command of a foot guards company in 1714 and a year later married Marjorie Murray (d. in or after 1765), daughter of David Murray, fifth Viscount Stormont, and sister of the Earl of Mansfield and the Jacobite James Murray, "Earl of Dunbar". On 5 October 1718 John Hay was created by James III & VIII (the "Old Pretender") Earl of Inverness, Viscount of Innerpaphrie and Lord Cromlix and Erne in the Jacobite Scottish peerage. The Old Pretender appointed him his Secretary of State in 1725, and his wife and brother-in-law governess and tutor to the royal children at the same time. Thus John Hay and John Murray became known as the "King's favourites".
