Overview
Lachlann Mac Ruaidhrí was a Scottish magnate and chief of Clann Ruaidhrí. He was a free-booting participant in the First War of Scottish Independence, who remarkably took up arms against figures such as John, King of Scotland; Edward I, King of England; the Guardians of Scotland; and his near-rival William II, Earl of Ross. Lachlann disappears from record in 1307/1308, and appears to have been succeeded by his brother, Ruaidhrí, as chief of Clann Ruaidhrí.
