Niall Glúndub, High King of Ireland

Niall Glúndub mac Áeda (Modern Irish: Niall Glúndubh mac Aodha, "Niall Black-Knee, son of Áed"; died 14 September 919) was a 10th-century Irish king of the Cenél nEógain and High King of Ireland. Many Irish kin groups were members of the Uí Néill and traced their descent from Niall of the Nine Hostages (Niall Noígiallach).

His mother was Máel Muire, daughter of Kenneth MacAlpin, King of Scots.
