In the reign of James I., the chief’s name was John Macarthur, and so great was his following, that he could bring 1,000 men into the field. In 1427 that king, in a progress through the north, held a parliament at Inverness, to which he summoned all the Highland chiefs, and among others who then felt his vengeance, was John Macarthur, who was beheaded, and his whole lands forfeited. From that period the chieftainship, according to Skene, was lost to the Macarthurs; the family subsequently obtained Strachur in Cowal, and portions of Glenfalloch and Glendochart in Perthshire. Many of the name of Macarthur are still found about Dunstaffnage, but they have long been merely tenants to the Campbells. The Macarthurs were hereditary pipers to the MacDonalds of the Isles, and the last of the race was piper to the Highland Society.

In the history of the main clan, we have noted the origin of most of the offshoots. It may, however, not be out of place to refer to them again explicitly.

The Campbells of Cawdor or Calder, now represented by the Earl of Cawdor, had their origin in the marriage in 1510, of Muriella heiress of the old Thanes of Cawdor, with Sir John Campbell, third son of the second Earl of Argyll. In the general account of the clan, we have already detailed the circumstances connected with the bringing about of this marriage.

The first of the Campbells of Aberuchill, in Perthshire, was Colin Campbell, second son of Sir John Campbell of Lawers, and uncle of the first Earl of Loudon. He got from the Crown a charter of the lands of Aberuchill, in 1596. His son, Sir James Campbell, was created a baronet of Nova Scotia in the 17th century.

The Campbells of Ardnamurchan are descended from Sir Donald Campbell, natural son of Sir John Campbell of Calder, who, as already narrated, was assassinated in 1592. For services performed against the Macdonalds, he was in 1625 made heritable proprietor of the district of Ardnamurchan and Sunart, and was created a baronet in 1628.

The Auchinbreck family is descended from Sir Dugald Campbell of Auchinbreck, who was created a baronet of Nova Scotia in 1628.

The Campbells of Ardkinglass were an old branch of the house of Argyll, Sir Colin Campbell, son and heir of James Campbell of Ardkinglass, descended from the Campbells of Lorn, by Mary, his wife, daughter of Sir Robert Campbell of Glenurchy, was made a baronet in 1679. The family ended in an heiress, who married into the Livingstone family; and on the death of Sir Alexander Livingstone Campbell of Ardkinglass, in 1810, the title and estate descended to Colonel James Callander, afterwards Sir James Campbell, his cousin, son of Sir John Callander of Craigforth, Stirlingshire. At his death in 1832, without legitimate issue, the title became extinct.

The family of Barcaldine and Glenure, in Argyleshire, whose baronetcy was conferred in 1831, is descended from a younger son of Sir Duncan Campbell, ancestor of the Marquis of Breadalbane.

The Campbells of Dunstaffnage descend from Colin, first Earl of Argyll. The first baronet was Sir Donald, so created in 1836.
