NELLIGAN Family History

Recorded as O'Niall, O'Neill, O' Naillan, O'Neligan, Naillan, Neligan and Nelligan, this prestigious Irish family claims descent from Domhnall, grandson of Niall Glun Dubh or Neil of the Black Knee, King of Ireland, who was killed by the Norsemen in 890 a.d. The family are said to have the oldest traceable genealogy in Europe, a remote ancestor being Niall of the Nine Hostages, the legendary 4th Century High King of Ireland. Traditionally, Irish family names are taken from the heads of tribes, revered elders, or some illustrious warrior, and are usually prefixed by "Mac" denoting "son of", or "O", grandson, male descendant of.
