In Gaelic the MacNabs are called Clan-an-aba, meaning, "Children of the Abbot". They claim to be descended from the Abbot of Glendochart. They held lands at Loch Tay, but these were forfeited following their opposition to King Robert the Bruce. King David II, in 1336, gave a charter of the Barony of Bovain, Glendochart, to Gilbert MacNab. They supported Montrose's Rebellion in 1645. The chief supported the Government in 1745, but the clan fought for Prince Charlie. The 12th chief is the subject of Raeburn's famous painting.
