County Monaghan
In 1585, the English lord deputy of Ireland, Sir John Perrot, visited the area and met the Irish chieftains. They wanted Ulster to be divided into counties, and that land in the kingdom of Airgíalla be split up and given to each of the McMahon chiefs. That is how County Monaghan was created. The county was divided into five baronies: Farney, Cremorne, Dartrey, Monaghan and Truagh, which was left under the control of the McKenna chieftains.
