All - The territory now called Longford anciently went by the names Teathba and Teffia. North Teffia was inhabited by the Glasraidhe, descendants of early inhabitants. By the 5th century Longford was divided into north and south. The northern territory became known as Cairbre Gabhra, after Cairbre a son of Niall of the Nine Hostages. Another son received the southern half. In the 8th century the Conmaicne (e.g. O'Farrells) invaded the Ui Cairbre and by the 11th century were the dominant people as the territory became known as Annaly, and was considered part of the province of Meath. It was controlled in the north by the O'Farrel Ban (White) and in the south by the O'Farrel Buy (Yellow). Longford was formed as a county (shire) in 1576.

• Ardagh - was formed from the territory of Sleughtwilliam (Mostrim parish), the territory of Clangillernan (Templemichael), and from part of the church lands in the parishes of Ardagh and Ballymacormick.
• Granard - Anciently this was part of a territory known as Cairpre Gabra, alias Corpre Tethbae, or North Teffia. The barony was formed from the territory of Clanshane (Granard, Abbeylara, and part of Colmcille parishes), and from the territory of Slewcarberie (Clonbroney and part of Colmcille parishes). Muintir Geradhain was located on the west side of Lough Gowna, where Ó Geradhain (Gaynor or MacGinver) is mentioned as lord here in the 11th century.

• Rathcline - was formed from the territories of The Callow (left bank of Shannon, Lanesboro to Ballymahon) and the territory of Clanconnor (part Kilcommoc, part Cashel).
