"Colla da Croich (85), was the founder of the Kingdom of Oriel [aka Oriel, Orgiall, Uriel] from whom many Ulster families take their origin. He was the son of Eochy Dubhlen (Dublin) and his mother was Alechia, daughter of Updar, King of Alba (Scotland). Muireadach or Colla da Chrioch (or Facrioch), meaning Colla of the Two Countries, Ireland and Alba, was one of three sons known as The Three Collas from whom descended many noble families of Ireland.

Colla da Chrioch was the first King of Ulster after its conquest by The Three Collas in the 4th century. He was the founder of the Kingdom of Orgiall. The Clan Colla ruled over that Kingdom, and were styled "Kings of Orgiall," down to the twelfth century. Oriel territory takes in the modern Counties Monaghan, Armagh and part of Louth.

The Monaghan Baronies map with civil parishes.

"The Barony of Cremorne in Monaghan," writes Dr. Joyce, "preserves the name of the ancient district of CriochMughdhorn or Cree-Mourne, i.e., the country (crioch) of the people called Mughdorna, who were descended and named from Mughdorn (or Mourne), the son of Colla Meann."
