 That appeared in a report to the Privy Council, where Arthur Chichester (1563-1625), the Lord Deputy of Ireland, said that chronic rebellions throughout the island had been inspired primarily by the seven septs of Queen's County.Among the seven, the Moore sept claimed an uninterrupted succession to the chieftainship of Loígis since the reign of Lugaidh Laeighsech, although they only assumed the surname Moore around the eleventh century.The Annals of the Four Masters record in 1018 the killing of Cernach Ua Mórdha, meaning Cernach, grandson of Mordha, from which derives the surname O'More, or Moore.
