The Campbells of Craignish (Mac Dúbhghaill Creaginnis in the Scottish Gaelic or Gàidhlig), form one of the oldest branches of the ancient and powerful Clan Campbell in Scotland.. They claim descent from Dugald Campbell, the second son of Sir Archibald Gillespic Campbell (b.1130), 5th Knight of Lochawe and 20th Chief of Clan Campbell at the time. Sir Archibald's first son, Sir Duncan Campbell, 6th Knight of Lochawe, was the founder of the principal branch of the Campbell family who today holds the title Duke of Argyll. The family - the eldest cadets of the house of Argyll. - was a virile race, its members in all generations, to their cost, little disposed to diplomacy or guile, but staunch defenders of their rights and good soldiers By alliances through marriage and conquest they quickly acquired large possessions, and their growing power was noticed with apprehension and jealousy by the parent house of Lochow. The family no longer owns the Lairdship of Craignish (see below). The coat of arms of Dugall Campbell of Craignish (below) is described in Nisbet's "A System of Heraldry" as 'gyronny of eight or and sable, the shield hanging from the mast of a lymphad sable'. The coat of arms left is the suggested arms of the current incumbent - the Ducal Crown is awarded because the holder is a Clan Chieftain, but it is tinctured blue because the original estates are no longer in possession of the Chieftain. The Chief of the Clan is also Chief of Clan MacInnes, and Chief of the Name MacIsaac, MacKissock and MacKessack. Craignish Castle The founder of the Campbells of Craignish, Dugall Maul Campbell became first Laird of Craignish and his descendants built and resided in Craignish Castle, on the Craignish peninsula in Argyll.. Ranald MacCallum was made hereditary keeper of Craignish Castle in 1510. However, the castle has long since escaped family hands, and in 1832 was rebuilt as a private mansion for Mr. Trench-Gascoigne, who owned nearly 6000 acres (24 km²) in Argyllshire. Today, the Castle has been converted into apartments and is owned privately.
