Domnall ua Néill
Domnall's children included Muiredach , whose son Lochlann may have been the ancestor of Domnall Ua Lochlainn , and Muirchertach , ancestor of the O'Neills of Tír Eógain . His grandson Flaithbertach Ua Néill was King of Ailech and the leading figure among the Uí Néill , certainly from the death of Máel Sechnaill in 1022 , if not earlier .
