From the tract termed the ‘Hereditary Proprietors (_Duthchusaigh_) of the Clann Fiachrach’ we obtain some further information. The territory possessed by the tribe appears under different names. These are _Triocha Cheud_, _Taoisidheacht_, or territory ruled over by a _Taoisech_, _Tuath_, and _Duthaidh_.[183] The first is the _Triocha Ceud_ of Ceara, and over it were three kings, O’Muireadhaigh, O’Gormog, and O’Tighernaigh. It seems to have been exceptionally large. Then we have five districts termed _Taoisidheacht_. The first is that of O’h-Uada and O’Cinnchnamha. Then that of O’Cearnaigh, containing the twenty-four Ballys of the termon of Balla, and therefore nearly as extensive as a _Triocha Ceud_, but the expression Termon indicates it as being church land. Then that of Ui Ruadin and of him is the _Dudhchus_ of O’Culachan. Then that of O’Birn and that of O’Gorrmghiolla, the latter containing seven Ballys and a half, or the fourth part of a _Triocha Ceud_. Then there are three _Tuaths_ mentioned. First the _Tuath_ of Partraighe, co-extensive with the parish of Ballyovey. Of this _Tuath_ we have two accounts. The first shows us the _Ri tuath_ and the _Taoisech_ distinct, for O’Gaimiallaigh was its _Ri_ and O’Dorchaidhe its _Taoisech_. By the second account it was the _Taoisigheacht_ of O’Dorchaidhe alone. O’Banan of Bally Ui Banan and Magilin of Muine were two _Mac Oglaichs_ or inferior chiefs. The _Tuath_ of Magh na bethighe contained the seven Ballys of Lughortan, the _Duthaidh_ of Mac an Bhainbh. The _Tuath_ of Magh Fhiondalbha, containing fifteen Ballys or half a _Triocha Ceud_, was the _Duthaidh_ of O’Cearnaigh. Then twelve _Duthaidhs_ or Estates are given, all connected with surnames. Of these seven consist of one Bally only. The _Duthaidh_ of O’h-Edhneachan consisted of three divisions, each containing three Ballys. The _Duthaidh_ of O’Faghartaigh contained three Ballys, and that of O’Caomhan containing the seven Ballys of Roslaogh. All of these tribes possessed a common origin with one exception, for it is added ‘that there was found no _Tuath_ without its hereditary proprietor of the race of Earc Culbhuidhe except this well-known _Tuath Aitheachda_,’ that is, tribe of the older subjected inhabitants, called _Tuath Ruisen_, the old name of Roslaog.[184]
