Tullyhaw finally became part of Ulster permanently in 1584 when Sir John Perrot shired Brefnie and created the county of Cavan. The influence of the Magaurans as a ruling family lasted longer than most Gaelic rulers, protected by the mountains and inhabiting an area more suitable for pastoral farming, they continued to elect a chief well into the 1800s. Lewis's Topographically Dictionary, published in 1837 records that "Tullaghagh, in the mountain district between the counties of Fermanagh and Leitrim, generally known as the "kingdom of Glan"....or the county of the Magaurans. To this isolated district there is no public road, and only one difficult pass....is densely inhabited by a primitive race of Mac Gaurans and Dolans, who intermarry and observe some peculiar customs; they elect their own king and Queen from the ancient race of the Magaurans to whom they pay implicit obedience. Tilling the land and attending the cattle constitute their sole occupation; potatoes and milk, with sometimes oaten bread, their chief food". This description of life in the Glan, with the exception to potatoes, could have been written 250 years earlier when a lot of Ireland was still ruled by Gaelic chiefs. Over 200 years after the collapse of the Gaelic political System, with the Industrial revolution in full flight, the Magaurans were still living the life of Gaelic chiefs in the mountains of Tullyhaw".
