Also known as Clan Donnachaidh, the Robertson clan are possibly descended from Donnchadh (Duncan), the second son of Angus MacDonald, Lord of the Isles.
The clan would eventually settle in the Scottish Highlands, particularly Struan in Perthshire. It would be in Perthshire that the chiefly family of the clan would settle at their historic seat at Dunalastair Castle, the stunning ruins of which can still be visited today.
The current clan chief is Gilbert Robertson of Struan. He is the 24th person to hold the position.
