Project Purpose

The purpose of this project is to show the patrilineal descent of the O'Neill Dynasty (the Irish Royal House of O'Neill, which was taken over and disbanded by King Henry VIII) from the progenitor of the Ui Neill, "Niall of the Nine Hostages -to- Niall Glundubh Mac Aedo, High King of Ireland, King of the Cenél nEógain - to Conn Bacach Mac Cuinn O'Neill, the last King of Tyrone, and his descendants. Further lineage will be explored when this line is complete.

Origin of the O'Neill Surname

"Ó NÉILL - Derivatives: O'Neill, O'Neal, Neill, Neale - A name given to some descendants of Niall Noigiallach, also known as "Niall of the Nine Hostages." It is the surname of several distinct families in different parts of Ireland, of which several clans and family groups are descended. [1]

Eoghan Mac Niall, son of Niall Noígiallach, was progenitor of the Kingdom of Cenél Eógain.

"Niall Glúndub mac Áedo (modern spelling: Niall Glúndubh mac Aodha) was a 10th-century Irish king of the Cenél Eógain and High King of Ireland. He was the 170th Monarch of Ireland and reigned for three years. While many Irish kin groups were members of the Uí Néill and traced their descent from Niall Noígiallach, the O'Neill dynasty took its name from Niall Glúndub rather than the earlier Niall."

It is from this Monarch the surname O'Neill or "Clan-na-Neil," Neilson, Nelson and Nilson are derived, as well as the Clan O'Neill.[1] [2][3]


Prior to this, the names were still expressed in a patrilineal manner as in Gaelic tradition. Niall's grandsons Flaithbertach mac Muirchertach O'Neill and Domhnall Mac Muirchertach O'Neill are believed to be the first of this direct line to use O'Neill as a surname, to distinguish the familial line as descent from Niall Glundubh. [1]

Early Kingdoms: The Uí Neill High Kings of Ireland - The Uí Neill was the designation of those claiming descent from Niall of the Nine Hostages. The list below shows the reigning Kings in order of succession and does not necessarily fall along patrilineal descent. This list is not covered under the name study.
