Éile & Éile Uí Fhógartaigh



Branching out of the race of Cian, son of Oilill Olum, the Clan Cian is found anciently in the territory of h-Éile Muman, among other places. A main branch descends from Cearbhal, lord of Ely, who was descended from Oilioll Olum. Various septs are noted of Éile (Ely).

Eile / Clan Cian - northeast Tipperary, southwestern Offaly - e.g. O'Carroll.
Eile Uí Fhogartaigh [barony of Eliogarty] - South Eile - e.g. O'Fogarty, cited as a Dal gCais sept.
Uí Fiachach Eile - in descent from Deachluath, son of Fiacha Muilleathan (Eoganacht).
Ui Flannacan Eli, alias Cenél Farga (Cinel Fearga or Cenél Arga), occupied the barony of Ballybrit, King's county.
Úi Luigdech Éile , descended from Lugaid, son of Ailill Flann Bec (Eoganacht).
Corca Eathrach Eli, aka Corco Athrach, alias Machaire Caisil, centered near Cashel and Holy Cross, descended from Aimirgin Glúngel.
Mec Con Medha of Tir Ele, MacConway, of Síl Ronain, of southern Uí Neill descent.

Septs included Ua Cearbhaill (O'Carroll), Ua Fhogartaigh (O'Fogarty), Ua Meachair (O'Meagher), Mag Corcrain (Mac Corcoran), Ua Flannacain (O'Flanagan), Ua Banain (O'Banan), Ua Cathail (O'Cahill), Mac Guilfoyle.

In O'Heerin's Topographical Poem it describes 8 tuatha under the King of Ely (the O'Carrolls of the Plain of Birra). The eight included Kinel Arga alias Cenél Farga (Ui Flannacan); Clan Rooney (Mag Corcran); Crioch Chein (O'Hegan); Clan Maonaigh (O'Dooley, formerly chief of Fartullagh); Clan Conligan (Mac Guilfoyle); Hy Deki (O'Banan); Crioch Keerin, or Uí Cairin and now anglicised Ikerrin (O'Meagher); and Tuath Faralt ( O'Hailchen). O'Heerin next describes Corca Tine and Ely the southern, who were possibly centered in the present Barony of Elyogarty in the County of Tipperary.

O'Donovan in his Ordnance Survey letters notes "From the poem of O'Heerin's it appears that before the Irish principalities were disturbed or dismembered by the Anglo Normans in the 12th century, Ely, the Kingdom of O'Carroll extended from Birr to Ely O'Fogarty in the County of Tipperary and that it comprised the present Baronies of Ballybritt, Clonlisk and Ikerrin." He goes on to cite the extent of Ely O'Carroll defined on the north by the boundary of ancient Meath (by the boundary of the Diocese of Meath); on the east by the ridge of the Slieve Bloom range of mountains (i.e. by Eile Uí Mhordha, aka Ely O'Morha); on the south by Eile Uí Fhógartaigh, aka Ely O'Fogarty (largely the barony of Eliogarty); and on the west perhaps by the baronies of Ormond (formerly part of Muscraighe Tíre).

Éile Uí Fhógartaigh , aka Ely O'Fogarty or Desceirt Éle, was centered in the barony of Eliogarty in county Tipperary, apparently also including a portion of the baronies of Upper Ormond and Ikerrin. The Ely O'Fogarty region formed the southern portion of a more extended territory simply referred to as Éile (Ely). Thurles is located in the heart of Eliogarty, and O'Donovan (Four Masters) describes this place as Dúrlas Uí Fogarta. The barony of Eliogarty was the patrimony of the O'Fogartys, i.e. the Síl Echach Bailldeirg, as O'Donovan (Poems) refers to them as. MacLysaght (Irish Familes) says of the O'Fogarty genealogy, "though located outside the area associated with the Dalcassian septs the O'Fogartys are counted as of Dalcassian origin."
