List of Famous people with last name Raghnaill

Domhnall mac Raghnaill was a Hebridean noble in the late 12th- and early 13th-century. He is the eponymous progenitor of Clan Donald. For this reason some traditions accumulated around him in the Later Middle Ages and Early Modern period. His vast impact on culture and in the centuries remains today. Despite his role as the historical figurehead of one of the world's most famous kindreds and surnames, there is almost no contemporary evidence yielding certain information about his life.

Ruaidhrí mac Raghnaill was a leading figure in the Kingdom of the Isles and a member of Clann Somhairle. He was a son of Raghnall mac Somhairle, and was the eponymous ancestor of Clann Ruaidhrí. Ruaidhrí may have become the principal member of Clann Somhairle following the annihilation of Aonghus mac Somhairle in 1210. At about this time, Ruaidhrí seems to have overseen a marital alliance with the reigning representative of the Crovan dynasty, Rǫgnvaldr Guðrøðarson, King of the Isles, and to have contributed to a reunification of the Kingdom of the Isles between Clann Somhairle and the Crovan dynasty.
