Munster - aka Mumhan, Mumu, Muinhneach, Mumhain

Munster in the Early Annals of Ireland



The Cenél Fearmaic are given as either Úi Fidgeinti or Dalcassian in origin, depending on which genealogy followed, and were represented by the O'Deas, O'Quins, O'Heffernans, et al. Origins of the Uí Cormaic are given as Úi Fidgeinti with their representatives the O'Hehirs, et al. The Corca Baiscinn are given in descent from a son of Conaire Mor ( c. A.D. 165), and related to the Corco Duibne of Munster and the Dal Riata of Ulster, with their later representatives cited as O'Donnell and MacMahon of Munster, among others.

The Uí Breacain are given as a Dalcassian sept in early genealogies, with their representatives including . The main septs of the Corco Mruadh, in descent from the Clanna Rory of Ulster, included O'Connor of Corcomroe, O'Loughlin of the Burren, O'Garbh, among others. The Tradaree (Tradraige) area included, among others, the Ó Neills of Cenél Dealbhaoith. O'Donovan's Tribes of Uí Fiachrach cites the tribes of the Tradraighe as remnants of the original Firbolg tribes of Connacht.

Tuadh Mumhan came into prominence as a separate region within the province of Mumhan (Mumu, Mumhain, et al) in conjunction with a rise in power of the Dál gCais. An ancient origin tradition of the Dál gCais connect them to the Déis Becc (aka Déis Tuaiscirt), a branch of the Déisi who conquered the Thomond region from the Connachta in the 5th century.

Dál gCais was originally a small kingdom ruled by the ancestors Brian Borúmha, including the eastern portion of the present County Clare. Brian's ancestors are said to derive from the sons of Cas, 7th in descent from Ailell Aulum (or Oilill Olum), and included Caisin (Ui Caisin, e.g. MacNamara), Aonghus Ceannathrach (Cenél Cuallachta), and Blat or Blod (Ui Blait or Uí Bloid, e.g. O'Brien, O'Kennedy), among others.

The early Dalcassian territories would eventually be formed into the medieval and more modern baronies of Tulla (formerly part Ó mBloid), Bunratty (formerly part Ó gCaisin & Tradaree), Inchiquin (formerly Cenél Fearmaic, and Tullyodea), the Islands (formerly part Uí Cormaic, and Clonroad), Clonderlaw (formerly part East Corcabaiscinn), Moyarta (formerly part West Corcabaiscinn), Ibrickan (formerly Uí Breacain), Corcomroe and Burren (formerly the tribal area of Corco Mruadh). The Ó mBloid and Ó gCaisin are given as Dalcassian septs, descended from the sons of Cas, 7th in descent from Ailell Aulum (or Oilill Olum), and represented by the septs of O'Brien, MacNamara (Clann Chuiléin), and many others in the region. The O'Briens and MacNamaras were dominant lords in this region for many centuries.
