From these sons derive some of the earliest recorded tribes of Leinster. Dál Niad Cuirp, the clan of Nio Corb, including his descendants Maine Mál and Cathaír Már. Maine and Cathaír were sons of Fedelmid Fer Aurglas m. Corbmaic Gelta Gáeth m. Niad Cuirb (Nia Corb) m. Con Corb (Cu Chorb). From Cathaír Már descended the tribes of Úa n-Dúnlainge & Úa Ceinselaich. Son of Cathaír Már: Rus Failgech, a quo Uí Failge, - Uí Dróna, Clann Colgcan, Clann Mugróin, Uí Bercháin, Uí Nialláin, Uí Berraide, Cenel Aitheamháin. Sons of Rus Failge included: Nath Í (Uí Flaind, Uí Chormaic, Uí Móenaig, Uí Berraidi) -- Brénaind (Uí Airmedaig) -- Óengus Find (Uí Máele Topair & Uí Chuilíne & Uí Máel Aithgén) -- Óengus Dub (Uí Maine)-- Dálán (Uí Onchon)-- Eochaid. Uí Failge Cathair Mór was the ancestor of the Free Tribes of Leinster: through his son Ross Failge descended the Uí Failge. The Uí Failge dynasty in later times are noted in the three septs of the Ua Conchobair Failghe (O'Connor Faly), the Uí Riacáin (O'Dunne), and the Clann Máellugra (O'Dempsey). The territory of Ua bhfailghe came to be anglicized as Ofaily or Offaley, now commemorated in the modern county Offaly. Under the O'Connor Faly, the Uí Failge are noted in the 16th century as one of the last Gaelic lordships to fall to the English Crown. The old territory of Offaly is described by O'Donovan in his Ordnance Survey letters. He notes the territory of Ui Failghe or Ophaley comprised the following Baronies: Geshill in the King's Co.; Upper and Lower Philipstown in the King's Co.; Warrenstown and Collestown in the same County; Ophaley or Offaley in the Co. of Kildare; Portnahinch and Tinahinch in the Queen's County. O'Donovan goes on to cite O'Heerin giving that the principality of Ofaley was originally subdivided into seven cantreds, viz.; Tuath Geisille [Geashill], Hy-Regan [Tinahinch], Clann-Maoilughra [ Upper Philipstown & Portnahinch], Clar Colgain [ Lower Philipstown], Tuath-Maighe or Tethmoy [Coolestown and Warrenstown], Magh Aoife or Fearann Ui Murchain [northern half of the Barony of Ophaley in the County of Kildare], and Tuath-Leighe [southern half of the Barony of Ophaley in the County of Kildare]. Keating in his History cites O Conchubhar Failghe with his family branches: i.e. O Caomhanaigh, O Tuathalaigh, O Branaigh, Mac Giolla Phadraig, O Duinn, O Diomasaigh, O Duibhidhir, muinntear Riain.

Clann Colgcan Septs of Clann Cholgaín noted in northern Offaly (centered in the barony of Lower Philipstown, Co. Offaly) were the septs of Ua hUallachain (O'Holohan or O'Houlihan) and Ua hAonghusa (O'Hennessy). Other Clann Colgcan septs noted in the ancient genealogies included the Uí Rotaidi, the Uí Muricáin, the Uí Bróen and the Uí Cholgan. MacLysaght (Irish Families) mentions that a branch of Clan Cholgain was located nearer to Dublin, the head of it being chief of Gailenga Beg on the north side of the River Liffey on the borders of Counties Meath and Dublin, before being displaced by the Anglo-Norman invasion (late 12th century). For reference, also see O'Hennessy of Gailenga Bec, and of Uí Mac Uais. MacLysaght also mentions the Offaly O'Hennessys spread into Tipperary and Clare - in the latter county they are now called Henchy, formerly Hensey. The Book of Ballymote mentions the descent of Clann Colcan from Colgu, son of Maelduin, however the genealogies in Rawlinson B502 seem to indicate Clann Colgcan in descent from Colgcan son of Mugróin.
