Ailéan mac Ruaidhrí

Ailéan mac Ruaidhrí was a leading figure in the thirteenth-century kingdoms of the Isles and the Scotland. He was a son of Ruaidhrí mac Raghnaill, and thus a member of the Clann Ruaidhrí branch of Clann Somhairle. Ailéan was a brother of Dubhghall mac Ruaidhrí, King of Argyll and the Isles, a significant figure who held power in the mid thirteenth century. At the time, the rulers of the Isles were fiercely independent of the Scottish Crown, and owed nominal allegiance to the distant Norwegian Crown. In 1259, Dubhghall's daughter married the son of King of Connacht, and Ailéan is recorded to have commanded the woman's tocher of one hundred and sixty gallowglass warriors.
