 The term Dunloe is believed to be an anglicization of the Irish term "Dún Lóich", meaning fort or stronghold of Lóich (the River Loe that runs through the Gap of Dunloe valley also derives its name from the same source).According to the "Annals of Clonmacnois, Keating" and the "Lebor Gabála Érenn" (LGE), Deala (or Dela) Mac Lóich was the father of the five chieftains of the returning Fir Bolg (Slainghe, Gann, Genann, Seangann, and Rudhraighe), who conquered Ireland and divided it into five provinces, each ruled by one brother.According to the "Annals of the Four Masters", the Fir Bolg ruled Ireland for 37 years from 3266 to 3303 B.C., but were themselves defeated by the returning Tuatha Dé Danann.
