Origins

Along with the Luighne, Delbhna, Saitne and Ciannachta, the Gailenga claimed descent from Tadc mac Cein mac Ailill Aulom. Francis John Byrne, in agreement with Eoin MacNeill, believes that "they were vassal tribes of fighting men whom the Connachta and Ui Neill ... planted on the lands they conquered." (IKHK, p. 69) While Byrne and MacNeill believed they originated in Connacht, recent research on the derivation of the term Connachta would indicate that they originated within Brega, and were transplanted west across the Shannon by the Connachta.

A genealogy, cited by Geoffrey Keating, states: "Tadhg son of Cian, son of Oilill Olom, had two sons, namely, Connla and Cormac Gaileang. From Iomchaidh son of Connla comes O Cearbhaill, and from Fionnachta son of Connla comes O Meachair. From Cormac Gaileang son of Tadhg, son of Cian, comes O Eadhra and O Gadhra and O Conchubhair Ciannachta. The following are the territories they acquired, namely: Gaileanga, east and west; Ciannachta, south and north; Luighne, east and west."

Rawlinson B 502 or Rawlinson B 512 contains the following genealogy:

Léocán m. Laidgneáin m. Máeláin m. Éicnich m. Dúnchada m. Cináeda m. Léocáin m. Donngaile m. Conchobair m. Moínaich m. Máel Mórda m. Adamra m. Dechraich m. Dergscáil m. Leae nó oe m. Cormaicc [Gaileang] m. Taidg m. Céin m. Ailella Auluimm.

Conquerors of Connacht

Byrne goes to say that the Gailenga and Luigni were closely associated as neighbours and allies in Connacht, "situated south of the Ox Mountains they formed a large block between the northern Ui Fiachrach and the Ui Briuin. They themselves dominated smaller tribes, and have some claim to be considered an over-kingdom, as recognised in the twelfth century when their lands were absorbed into the diocese of Achonry. Their ruling families of O'Gara and O'Hara remained prominent well into the seventeenth century. The baronies of Gallen in Mayo and Leyney in Sligo, along with Corrand and Coolavin in the Curlew Mountains, lloming over the fertile plain of Moylurg, into which the Ui Briuin Ai were to expand, were crowded with small tribes, some of whom are intimately connected with the origin legends of the Connachta." (p.233)

Kingdoms of Gailenga

Septs of the Gailenga Móra and Brega adopted the surnames Ó Lóthcháin, Ó hAonghusa, and Mac Maoláin.

The Uí Briúin were a royal dynasty of Connacht. Their eponymous apical ancestor was Brión, son of Eochaid Mugmedon and Mongfind, and an elder half brother of Niall of the Nine Hostages. They formed part of the Connachta, along with the Uí Fiachrach and Uí Ailello, putative descendants of Eochaid Mugmedon's sons Fiachra and Ailill. The Uí Ailello were later replaced as the third of the Three Connachta, through genealogical sleight of hand, by the Uí Maine.

The Ciannachta were a population group of early historic Ireland. They claimed descent from the legendary figure Tadc mac Céin. Modern research indicates Saint Cianán and his followers may have been the origin behind the tribal name as it is a late construction similar in form to Eóganachta and Connachta. They first appear in historical sources in the 6th century, and were found in several parts of the island, including in Brega and Airgialla. The Ciannachta groups were absorbed over time. Modern descendants have formed a Clan Cian society.
