gradually come under the domination of the Cenel Eoghain and pushed southwards, shrunk further in the advance of the Normans in the late 12th and early 13th century. Almost all of the Airgiallan sub-kingdom of Airthir was retained by the Ó Hanlons who lost only the southern tip of their territory to the Normans. The O'Hanlons continued to rule Orior without interruption for the next four centuries and were known henceforth as the lords of Orior. The O'Hanlons lost the town of Dundalk in the south of Airthir (modern day County Louth), but were allowed to stay as paying tenants. The town's coat of arms still has an ermine boar representing the O'Hanlons supporting a shield with the De Verdon coat of arms. 1246. The O’Hanlons move south from Oneilland. Murrough O’Hanlon is described as "Lord of Orier". Orier included most of modern-day eastern Co. Armagh, stretching well into Louth, and over the Cooley mountains to the shore of Carlingford Lough. 1254. Following the Norman invasion of Ireland, "The O’Hanlon" is listed among the Ulster chieftains to whom the English King Henry III appealed for aid in his war against the Scots. 1273. Eochaidh "Eochy" O’Hanlon is listed as 'king of Orghialla'. It is the first known use of the name "Eochaidh" by the O'Hanlons, which means "horseman" or "jockey" in Gaelic.

The O’Hanlon imposed 'black rents' upon English colonists living in and around Dundalk. Black Rent was insurance against incursions and other plundering; a colonist paid the rent, The O’Hanlon did not raid them in response to their trespass. It is thought that he levied the rent over areas south of Dundalk, too. 1314–1315. The O’Hanlon sept changes allegiances when Edward Bruce, in support of his brother Robert Bruce, in his war against the English, invaded Ireland and swept southwards. Bruce had seized O’Hanlon's son and heir, sent him to Scotland and demanded The O’Hanlon's good faith. 1321. Manus O’Hanlon, lord of Orior, is blinded by sept members under the leadership of his kinsman, Niall, son of Cu-Uladh O’Hanlon, on Spy Wednesday. Niall becomes lord of Orior, submitting to Edward III. The men of Dundalk march north and kill Niall. 1341. The men of Dundalk entered
