Rosguill Tri Tuatha

clipped from generation13.com Rosguill, a promontory (or Ross) in the barony of Kilmacrenan, Co. Donegal, between Sheep Haven and Mulroy bay, i.e. in the parish of Mevagh. O'Dugan (Poems) cites that Ros-Guill and Ros-Iorguil belong to MacGillatsamhais. Ros-Iorguil, or Irguill, is equated to Horn Head, to the west of Ros Guill, in the index to the Four Masters. Both areas are west of Fanad. The areas of Rosguill (now Downing's & Carrigart), Doe (now Creeslough & Dunfanaghy), Cloughaneely (now Falcarragh ) and Tory Island, were later ruled by the Mac Sweeneys from Doe Castle. These were the MacSweeney Na Doe (Mac Suibhne na d'Tuath), lords of Na Tuatha. The district called Na Trí Tuatha, or Tuatha Toraighe, was an area extending from Ros Guill and Mulroy Bay in the east to Gweedore Bay in the west, with Tory Island included. Note: Trí Tuatha, not to be confused with the Three Tuatha of county Roscommon.
