History of the Donohoe Clan



The Clan Donohoe (O’Donohoes or Uí Donnchadha) of Breifne were chiefs of the Teallach Dhúnchadha, which was traditionally a branch of the Uí Briúin Bréifne, itself traditionally a branch of the royal Uí Briúin Aí, rulers of Connacht. The Teallach Dhúnchadha was a tuath which occupied approximately the territory later known as the barony of Tullyhonoho or Tullyhunco, which included the parishes of Killashandra and Kildallan. The O’Donohoes were replaced in the early 1200s by the MacKiernans (Mac Thighearnán), another branch of the tuath.

In 1159, the chief of the Uí Donnchadha (first name not given) is mentioned in the Annals of Ulster as killed while fighting with the other Uí Briúin Bréifne under Tiernan O’Rourke (Thighearnán Ua Ruairc), King of Breifne, among troops of Rory O’Connor (Ruaidrí Ua Conchobhair), King of Connacht, at the bloody battle of Ferdia’s Ford (Ardee, Co. Louth) against Moriarty O’Loughlin (Muircertach Ua Lochlainn), King of Ulster (Ulaid), and from 1156 King of All Ireland, and Donogh O’Carroll (Donnchadh Ua Cearbhaill), King of Oriel (Airgailla), which included Co. Louth within its territory. In 1166 King Donogh of Oriel transferred his allegiance from King Moriarty of Ireland (causing his downfall) to King Rory of Connacht, who then became King of All Ireland.
