Nogher
Nogher—This name is the anglicised form of a sept of the O'Connors (O'Conchobhair), who ruled in Western Hy Breasail or Ui Breasail Macha, now a part of the O'Neilland Baronies in County Armagh, along with the O'Longans and O'Duvanys; the O'Larkins and O'Garveys ruling in Eastern Hy Breasail; the O'Heaneys ruling in Clan Kearney, now the district of Markethill, Co. Armagh.
In the districts surrounding Banbridge, in the Northern parts of Co. Armagh, and about Downpatrick, the name is anglicised respectively Noher, Nogher, and Nocker.
I must refer to another sept name in Ulster, that is, McNogher. This name is distinct from the above sept name. In the districts of Ballymoney, Co. Antrim, and the district surrounding Limavady, and other parts of S.E. Derry, the names McNogher, McNoher, Menocher, Minogher, and McNoger are the anglicised forms of an ancient sept in Co. Derry. McNogger of this sept was the right hand man of Seáin Mór O'Neill.
This sept, formerly O'Connor, ruled for centuries over Cianachta, in Co. Derry, before they were dispossessed by the O'Kanes of the Kinel Owen. They were of the Eoghanacht of Munster, descended from Teige, son of Cian, son of Oilioll Olum, King of Cashel in the 3rd century, and from their ancestor Cian, the district got the name of Cianachta.
It seems that the Munstermen must have had a base in Derry and Northern Antrim from which they passed over into Scotland, establishing the Eoghanacht Clans in Mar and other parts of Aberdeen, in Stirling, and in Dumbarton, the High Stewarts of Mar in Aberdeen, and of Lennox (Leamhna) in Stirling, being descended from Corc of the Eoghanacht. This colonisation of Scotland by the Irish Scots occurring long before the colonisations led by Fergus Mac Erc, who was of the line of Conn of the Hundred Battles.
