 The land that Moy House stands on was purchased by John Campbell, of the Campbells of Cawdor, from the Bishop of Moray in 1579.It remained in the Campbell's possession until 1733, when the seventeenth-century 'auld house' that had been build on the site was acquired by Major George Grant.The wings projecting to the east added to the house in the 1750s by Collen Williamson, and in 1862 Grant's nephew, Sir Ludovic Grant of Grant, had the original part of the house demolished, at a cost of £5, and a new central block built.
