Coll Macdonald, 16th of Keppoch (c.1664-1729), was a Scottish clan chief and prominent Jacobite, active in both the 1715 Jacobite rebellion and Dundee's rising of 1689. He was chief of the Macdonalds of Keppoch, holding land in Lochaber. He is sometimes known as "Coll of the Cows" (Nam-bo) or "the Colonel of the Cows", a nickname apparently given by John Graham, 1st Viscount Dundee. Along with other chiefs of Keppoch he was also referred to by the Gaelic patronymic title Mac Mhic Raonuill, "the son of Ranald's son". Life Keppoch was the son of the 15th chief Archibald (Gilleasbuig) Macdonald and Mary Macmartin of the Macmartin Camerons. The anti-Jacobite Whig historian Thomas Babington Macaulay mentioned Keppoch in his History of England, describing him as "an excellent specimen of the genuine Highland Jacobite [...] insulting and resisting the authority of the crown". Keppoch first appears in records in 1682, as a student at the University of St. Andrews. Learning of his father's death, he left university to make funeral arrangements and (as claimed by a petition he submitted in 1683) to make an "accommodation" with his father's landlord, the chief of Clan Mackintosh. Keppoch claimed that Mackintosh had him summarily incarcerated in Inverness Tolbooth, while Mackintosh claimed that Keppoch was liable to pay taxes owed by his father. From this point the dispute between the Macdonalds of Keppoch and the Mackintoshes escalated, with Mackintosh obtaining Government support through a Commission of Fire and Sword against Keppoch, who later retaliated by burning the Castle of Dunachton. At the Battle of Mulroy in 1688, often described as the last "clan battle", Keppoch and his clansmen were victorious over a larger force of Mackintosh men, backed by government troops, sent into Lochaber to occupy it. Keppoch's activities were to be a source of trouble to the authorities for many years. Colonel John Hill, governor of Fort William, was to write of Keppoch that "he speaks better than any Highlander I know, and is a pretty fellow [...] 'tis pity but he were honest". Matters between Keppoch and Mackintosh were eventually smoothed over by a 1700 legal agreement, which confirmed Keppoch in his lease of some of the disputed lands. Perhaps hoping to gain support in his local disputes, Keppoch became a committed Jacobite supporter subsequent to the Glorious Revolution. Along with his brother he appears to have spent some time in Ireland with the
