The Maguire sept is primarily associated with modern-day County Fermanagh. They possessed the entire county, also known as Maguire’s Country, from about 1200 C.E. and maintained their independence as Lords of Fermanagh down to the reign of James I, when their country was confiscated like other parts of Ulster. The Maguires supplied Chiefs or Princes to Fermanagh, from about A.D. 1264, when they supplanted the former Chieftains (O’Daimhin, or Devin). They were inaugurated as Princes of Fermanagh on the summit of Cuilcagh, a magnificent mountain near Swanlinbar, on the borders of Cavan and Fermanagh; and sometimes also at a place called Sciath Gabhra or Lisnasciath, now Lisnaskea.
