Aodh was Tanist of Cenel Eoghain. "The Fews" (Irish: na Feadha) is an area in County Armagh that was a sub-territory under the O'Neills of Tyrone and is roughly equivalent to the area of the parish of Creggan. This O'Neill branch is related to the O'Neill of Tyrone through King Eoghan Mor, circa 1432–1436. The king's younger son Aodh (Hugh) pushed in the territory known as the Fews and conquered its various independent lordships. Aodh then established an independent chieftainship under his father and then brother.
