Argyllshire is the home of this clan. The Fergusons of Strachur claim to be descended from the Royal House of Dalraida. The Fergusons of Kilkerran descend from Fergus, who held his possessions by a charter granted to him by King Robert I. Sir John Ferguson of Kilkerran was, in 1708, created a baronet. The Fergusons of Atholl had charters for their lands from Balliol and King Robert the Bruce. During the 1745 Jacobite Rising the Atholl Fergusons supported Prince Charlie. There are some prominent branches of the Clan Ferguson in Aberdeenshire, Banffshire, Kincardineshire, Dumfries and Galloway.
