 The MacGillivrays were persecuted by their Calvinist and Presbyterian neighbors owing to their support of Episcopal polity of the church.Along with most of the other clans of the Chattan Confederation, the MacGillivrays were staunch Jacobites in both the Jacobite rising of 1715 and the Jacobite rising of 1745.During the 1745 rising, the chief of Mackintoshes and clan Chattan was however a serving officer in the Black Watch regiment of the British Army, but his wife, Lady Anne Mackintosh (née Farquharson), rallied the Chattan Confederation in support of the Jacobites and placed chief Alexander MacGillivray in command of the clan Chattan regiment.
