  Eugenius
  Eogan, son of Niall Noígiallach, was an Irish king founded the kingdom of Tír Eógan (modern County Tyrone) in the 5th century. He was also the ancestor of the Cenél nEógain dynasty and their septs (O'Neill, O'Docherty, O'Boyle, etc).
  (Wikipedia)
  
  Eogan was a close friend of Saint Patrick and received Patricks blessing.[2] With his brother the high king Lóegaire mac Néill (d.462), he was one of the judges in a dispute over the succession to Amalgaid (d.440), king of Connacht among his sons competing to rule their territory of Tir Amalgaidh in northwest Connacht. [3]
  
  Eoghan, King of Tír Eógan, and Prince of InnisEoghan is buried at St. Patrick's Church in Iskaheen, Innishowen, Donegal. A plaque there states "Eoghan Prince of Iniseoghain, Son of Niall of the Nine Hostages. Died 465 of grief for his brother Conall. Baptised by Patrick and buried in Uisce Chaoin"
  
  His sons included Muiredach mac Eógain, his successor in Ailech; Fergus, founder of the Cenél Fergusa; and Echach Binnich, founder of the Cenél mBinnig

And it was that Oenghus who went on an expedition to the King of Teamhair (Tara) so that he formed a friendship with him and he fought a conflict on his behalf, namely the battle of Mullach Feadha; and there was destruction as a result of (?) the battle and to Oenghus until he called his hound, namely Guan [which] had been tied to the stone of the ford, so that the hound, namely Guan, came at the call (voice) of his master, so that he won the battle afterwards, so that he was given many territories and land, so that he divided it between (?) his seven sons afterwards. One of his sons [was] Echrach from whom are the Clann Oenghusa in Uibh Uais Breagh; [there was] another son of his in Crích Fer Cúl re Tulen in the north from whom are Clann Oenghus Cúl and many others.”
