"Between the fifth and twelth centuries the Ele, a tribe possibly of Laginian origin, were
forced southwards by the Ui Neill expansion into south Midhe.....
In historic times the genealogists invented a Munster pedigree for the Ele, making them, according to the Book of Leinster, Cianachta,
descended from Tadhg Mac Cein, grandson of Oilill Olium, an ealy king of Munster."

VIII. The Laigin
The Laigin, or Dumnonii, were the third
ethno-tribal group to come to Ireland, coming from Gaul shortly before the Gaels
themselves, sometime during the first century B.C. Branches of the Dumnonii settled first
in the Devon-Cornwall area before others moved on to Ireland (Chapter III).
In southern Britain their kingdom gave its name to Devon (Dumnonia). In
the time of King Arthur (ca. A.D. 500), as the tribe most closely associated with that
great Pendragon, these Devon Domnonii established a dual kingdom which included the north
coast of Brittany (Domnonie), from whose royal house eventually sprang the House of
Stewart (which house inherited the crown of the Scots in 1371 and that of England in
1603). The Stewarts are covered under the chapter on the Normans, having come to Scotland
in the wake of Norman conquest of England, in which they served as allies of the dukes of
Normandy.
In Ireland the Dumnonii were generally known as the Laigin, and
originally became overlords in the southeastern and central regions, and in Connacht. From
there they later spread to other parts of Gaeldom, as we shall see.
Tribes of the Laigin
The Cianacht
The Cianacht encompassed the OConnors (O
Conchobhair) of
Keenaght, and the Luighne. The OConnors were lords of Keenaght, County Derry, until
dispossessed by the OKanes shortly before the Anglo-Norman invasion in the twelfth
century. The Luighne were of County Sligo, where they had settled as fighting men to the
Northern Gaels in the early centuries A.D. The Cianacht were closely related to the
Dealbhna and Saithne.
The Luighne or "race of Lugh," included the families of
OHara (O hEaghra) and OGara (O Gadhra). The OHaras descend from Eaghra,
Lord of Luighne (now the Barony of Leyney) in South Sligo, who died in 926. In the
fourteenth century the OHaras divided into two branches, the heads of which were

known as OHara Boy (Buidhe), the
Yellow OHara, and OHara Reagh (Riabhach), the Speckled or Brindled
OHara. A branch of the family settled early in County Antrim, and became very
important there.
The OGaras were once one clan with the OHaras, and together
their territory, Luighne, included the modern baronies of Corran and Leyney in South
Sligo, and Gallen and North Costello (Sliabh Lugha) in Mayo. About the end of the tenth
century the two families separated, and divided the territory between them, the
OGaras taking the Mayo portion. They were driven from their territory by the
Jordans, Costellos and other Anglo-Norman settlers, and
resettled in Greagraidhe, in Sligo, now
the Barony of Coolavin, and were later known as lords of Coolavin. They built their
stronghold, Moygara, at the northeastern extremity of Lough Gara. Branches went to Munster
before the end of the sixteenth century, and are known as Geary or Guiry. The
ODuanys or Devanys of Sligo are a branch of the OGaras.
The Eile
The Eile were originally a tribe of western Kings County (Offaly),
where place-names recall their early residence in that region. After the battle of Druim
Derge (A.D. 516), at which battle they were decisively defeated by the expanding southern
Ui Neill, they migrated to the area known after them as "Ely" in the south of
Offaly and including northeast Tipperary. Their chief families in later times were the
OCarrolls of Ely, the OMahers, the ORiordans and the OFlanagans.
The OCarrolls (O Cearbhaill) descend
from Cearbhaill, Lord of Ely, who was one of the leaders at the famous battle of Clontarf
in 1014. The head of the OCarrolls was originally lord of all Ely, but after the
Anglo-Norman invasion their power was restricted to South Offaly, which was subsequently called Ely OCarroll.
The Ui Cairin or OMahers (O Meachair) are of the same stock as
the OCarrolls, and were lords of Ui Cairin, now the Barony of Ikerrin, in the old
Ely territory in Tipperary. After the Anglo-Norman invasion, Ikerrin was added to Ormond,
but The OMaher (chief of the sept) was left in control of the territory as tributary
to the Butlers, the Anglo-Norman earls of Ormond, under whom they flourished.
The ORiordans (O Rioghbhardain) are a branch of the
OCarrolls of Ely, and probably descend from Rioghbhardan, son of Cucoirne O
Cearbhaill, Lord of Ely, who fell at the battle of Sliabh gCrot in 1058. As late as 1576 a
"Gaven O Rewrdane" was a "freeholder" in Ely OCarroll, and one
of the most important followers of Sir William OCarroll. By this time branches had
spread into Leix and Kilkenny, but even earlier the greater portion of the sept had
removed to Cork and Limerick. In 1597 Maurice ORiordan of Croome was attainted by
the English, his lands being given to a George Sherlocke.
The OFlanagans (O Flannachain) are of the same stock as the
OCarrolls of Ely, and were chiefs of a territory known as Cineal Arga, now the
barony of Ballybrit, in southeast Offaly.
