List of Famous people with last name Ruaidhri

Ruaidhrí Mac Ruaidhrí was a fourteenth-century Scottish magnate and chief of Clann Ruaidhrí. He was an illegitimate son of Ailéan mac Ruaidhrí, and is recorded to have participated in the kindred's military actions against supporters of both the English Crown and Scottish Crown. Following the apparent death of his brother, Lachlann, Ruaidhrí appears to have taken control of the kindred, and firmly aligned the family with Robert I, King of Scotland. Ruaidhrí may well be the member of Clann Ruaidhrí who is recorded slain at the Battle of Faughart in support of the Bruce cause in Ireland. After his death, Ruaidhrí's half-sister, Cairistíona, attempted to transfer the Clann Ruaidhrí territories outwith the family. Ruaidhrí was survived by a daughter, Áine, and an illegitimate son, Raghnall. The latter fended off Cairistíona's actions and succeeded to the chiefship of Clann 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.

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.

Raghnall Mac Ruaidhrí was an eminent Scottish magnate and chief of Clann Ruaidhrí. Raghnall's father, Ruaidhrí Mac Ruaidhrí, appears to have been slain in 1318, at a time when Raghnall may have been under age. Ruaidhrí himself appears to have faced resistance over the Clann Ruaidhrí lordship from his sister, Cairistíona, wife of Donnchadh, a member of the comital family of Mar. Following Ruaidhrí's demise, there is evidence indicating that Cairistíona and her powerful confederates also posed a threat to the young Raghnall. Nevertheless, Raghnall eventually succeeded to his father, and first appears on record in 1337.

Dubhghall mac Ruaidhrí was a leading figure in the thirteenth-century Kingdom of the Isles. He was a son of Ruaidhrí mac Raghnaill, and thus a member of Clann Ruaidhrí.
