The Mac GUIires took this name from Uildhie, one of their ancient chiefs, and they are of the race Clan Colla, of the same descent as the MacMahons, Lord of Monaghan; The O'Hanlons, chiefs of Orier in Armagh; The O'Kellys, Lords of Ui Mani, in Glaway and Roscommon. In O'Dugans Topography of the twelth century, Mac Uidhie,or Mac Guire, is given as chief of Feara Monach, or Fermanagh, and designated in terms which may thus be translated; "Mac GUire, the chief od hosts, Rules the might men of Manach, At home magnificents in presents, The noblest chief in hoispitality."
