THE Chief of the Clan Robertson, known also as the Clann Donnachaidh, was Donnachadh Reamhar, otherwise known as Duncan de Atholia, who was male descendant of the ancient Celtic Earls of Atholl. The clan, however, count their Chiefs from Duncan, under whom they first appear as a clan in support of Robert the Bruce Duncan’s friend and kinsman. “The Robertsons of Struan,” says Skene, “are unquestionably the oldest family in Scotland, being the sole remaining branch of the Royal House which occupied the throne of Scotland during the eleventh and twelfth centuries.” From first to last the clan is noted for its loyalty to the Stewarts. On the murder of James I at Perth, it was Robert, the Chief of Clann Donnachaidh, who captured his murderers, for which act he had many honours conferred on him by King James I’s successor; and to further commemorate this, father and son took the name of Robertson, which the clan has since retained. Their territory, it is said, at one time extended from the watershed of Rannoch Moor to the gates of Perth. One of the most famous Chiefs was Alexander Robertson of Struan, known as the “Poet Chief.” The Chiefs had castles in Rannoch and at Invervack, near Struan; later, and up to 1860, their principal residence was Dunalastair; other residences were Carie, Dall and Rannoch Barracks. The Chief of the clan is styled Struan-Robertson.
THE MacGillivrays are Celts. They are descended from a warrior named Gillivray, who had his stronghold at Dunmaglass, and who, about the thirteenth century acknowledged himself and his posterity a branch of Clan Chattan under the 5th Mackintosh. The MacGillivrays of Mull and Morven have been said to be a branch of Dunmaglass. In 1579 mention is made of Archibald MacIlvoray in a case between the Laird of Luss and others. The Rev. Martin McGillivray, living in Mull about 1640, carried a claymore, and told Maclaine of Lochbuie that he would use it if he did not pay him his stipend. The MacGillivrays fought for the Old Chevalier at Sheriffmuir in 1715. When Mackintosh refused to lead his clan, which Lady Mackintosh had raised for Prince Charlie, MacGillivray of Dunmaglass took command. He fought like a lion at Culloden, and fell, wounded, in front of Cumberland’s 4th Regiment. He was alive next day, and was, by Cumberland’s orders, brutally murdered. The Clan Aonghais (Macinnes) formerly wore MacGillivray tartan.
