Dynasties and Territories of Connacht

The terms Uí Briúin and Uí Fiachrach refer to dynasts of the sons of Eochu Mugmedón, a fourth century 'high king' of Ireland. Eochu's son Bríon was the ancestor of the Uí Briúin, who along with the descendants of Eochu's son Fiachra Foltsnaithech, ancestor of the Uí Fiachrach, were to rule the province of Connacht for seven centuries. The Uí Briúin split into three main groups, the Uí Briúin Ai (O'Conor, ...) of east-central Connacht, the Uí Briúin Seola (O'Flaherty, ...) of southwest Connacht, and the Uí Briúin Bréifne (O'Rourke, O'Reilly, ...) of northeast Connacht. The Uí Fiachrach divided into two main branches, the Uí Fiachrach Aidne (O'Cleary, O'Heyne, O'Shaughnessy, ...) of southern Connacht, and the Uí Fiachrach Muaidhe (O'Dowd, ...) of northwest Connacht. One of Eochu Mugmedón's other sons was Niall [of the Nine Hostages], ancestor of the Uí Neill, whose descendants were to dominate the Irish high kingship over a similar extended period.

In the 9th-10th century, other noted territories in Connacht included Uí Maine (O'Kelly), Uí Maille (O'Malley), Luigne and Gailenga (O'Hara and O'Gara), Conmaicne Mara , Delbna , Uí Ailella , Cairbre (Sligo), Dartraige , Calraige , Sogaine , Conmaicne Réin (e.g. MacRannall), Conmaicne Cúile Tolad, and the Tri Tuathas .

Other groups and territories in the Connacht region included the Fir Chera, Ciarraige, Partraige, Corca Fhir Tri, Grecraige, Masraige, Corco Moga, Gamanraide, Fir Domnann, and Medraige.

The traditional boundaries of Connacht in this era included the Uí Fiachrach Aidne in the south, the river Shannon in the southeast, the Conmaicne Réin and Uí Briúin Bréifne in the northeast. Click here for a Physical Map of the Connacht region.

Connacht - General Information from the Annals.

Uí Briúin - The early genealogies have Brión, son of Eochu Mugmedón, as the progenitor of the Uí Briúin royal families of Connacht. From Brión descend the Uí Briúin of Connacht, including those of the Uí Briúin Ai, Uí Briúin Breifne and Uí Briúin Seola. The unrelated Uí Briúin Cualann were of the southern Dublin area of Leinster.

The Annals cite with general reference to the Uí Briúin:

Uí Briúin Ai - or "Teora Connacht" of Co. Roscommon. Noted chiefs of the Uí Briúin Ai in Roscommon, and kings of Connacht included the O'Conor sept, of the Sil Murray. The main branches of this sept were O'Conor Don, O'Conor Roe and O'Conor Sligo, these being descended from Conchobhar, King of Connacht (d. 970). In early medieval times, the four families ranking as royal lords under O'Conor [Don] included:
Ó Maoilbreannain (Mulrennan) of Clan Cathail , chief of Clanconnor (in Castlereagh barony)
Ó Roduibh (Mac Geraghty) of Clan Tomaltaigh and Siol Murray, chief of Muintir Roduiv (in Roscommon barony).
Ó Fionnachta (O'Finaghty or Finnerty) of Clan Murchadha , in the territory of Clanconway lying on both sides of the River Suck, in both Co. Roscommon and Galway.
Ó Flannagain (O'Flanagan), chief of the race of Cathal, the son of Muireadhach Muilleathan, seated between Mantua and Elphin.

Other principal septs subject to O'Conor in early times included those with military duties: MacBranan, MacDermot, MacDockry, O'Flinn and O'Hanly -- those with naval responsibility: O'Flaherty and O'Malley -- those with administrative function: O'Beirne and O'Teighe. The chief poets included O'Mulconry and the chief stewards included O'Flanagan and O'Kelly.

Of the same stock as O'Connor included the MacDermots of Moylurg, MacDonaghs of Corran (Tireril), MacManus of north Roscommon (Tír Tuathail, Kilronan parish) , Ó Roduibh (Mac Geraghty) of central Roscommon, Ó Fionnachta (O'Finaghty) of Sil Murray, Ó Flannagain (O'Flanagan), Mac Dail-re-Deachair (MacDockery) of Sil Murray, O'Beirne, ...

The Annals cite:

Síol Muiredhaigh - or "Síl Murray", of the Co. Roscommon area, was the territorial and dynastic name of the clans descended from Muireadhach Muilleathan of Magh Aei, King of Connaught, son of Fearghus, who died about 700 A.D. From Keatings Genealogies, some of the septs of Síl Murray included O Flannagain (O'Flanagan), O Maoilbhreanainn (O'Mulrennan), O Maoilmhoicheirghe (MacDockery?), O Birn (O'Beirne), O Fallamhain (O'Fallon), Mac Shamhradhain (MacGovern), O Coincheanainn (O'Concannon), Mac Oireachtaigh (MacGeraghty), Mac Diarmada (MacDermot), Mac Maghnusa (MacManus), O Gealbhuidhe (O'Gilboy?), and O Conchubhair (O'Conor). It should be noted that other genealogies place the septs of O'Fallon and O'Concannon as part of the Ui Maine of Connacht. The genealogies of MacFirbis mention O Lachtnain (O'Laughnan) of Siol Muireadhaigh.

Uí Briúin Seóla - in the territory of "Iarthair Connacht" in Co. Galway. O'Flaherty, descendants of Flaithbheartach, were chiefs of this sept which settled east of Lough Corrib, County Galway by the middle of the 8th century. By the early 13th century they were driven to the Connemara peninsula of Galway where they held sway for 400 years.

Clann Cosgraigh
Mac Aedha (Mac Hugh, also called Hughes) was chief of Clan Cosgraigh, a district on the eastern side of Lough Corrib in Galway, where they were chiefs of the barony of Clare. They are cited by McLysaght of the same stock as O Fhlaithbheartaigh (O'Flaherty) of western Connacht. MacFirbis' Book of Genealogies mentions Cloinne Cosgraigh in connection with the Cenél Dubáin , with territory from Glas Uair to Tamhnacha in Connacht, west of the river Suck. Their lands were acquired by the Síl Shenchan according to the same source.

Note: There were other Clann Cosgraighs in Ireland. For example the Clann Cosgraigh (O'Coskry, Coskerry, Cosgrave) of Benntraige, on the plain of west county Wexford.

The Annals cite:

Uí Ailella - their ancient territory is described in southeast Co. Sligo, which included the baronies of Tirerril and part of Corran. The early tribe of the Calraighi Mora are also cited early in Corran. The name Uí Ailella apparently comes from an ancient reference, that of Ailill, son of Eochuid Mugmedón, a quo Úi Ailella Connacht. Their territory is referenced as Uí Ailella, Tir Ailella, Tir Oilella, and finally corrupted into Tirerril. Very little information seems available on the early lords of Uí Ailella, and it is not until the 13th century that we find reference to the notable families of the area, i.e. those of the Ui Briuin. This includes the MacDonnchadha (MacDonagh) and their higher ranked cousins the MacDiarmada (MacDermot) of clann Mhaoil Ruanaidh. The O'Floinn (O'Flynns) were noted as chiefs of Síol Maoil Ruanaidh in co. Roscommon, in the 12th through 14th centuries.
The Mac Donagh surname originates from Donnchadh, son of Tomaltach na cairge (of the rock) ua Mac Diarmata, who was King of Moylurg 1197-1207. They later split into two groups, one based with one based in Colloney and Ballindoon (Tirerril), and the other in Ballymote (Corran). The MacDonaghs were vassals of the MacDermots until some time in the 15th Century when they came under the lordship of O'Donnell and O'Conor Sligo.

The Annals cite for Ui Aillela, et al:

Uí Fiachrach - The main septs of this clan group included those of the Uí Fiachrach Aidne and the Uí Fiachrach Muaide (below). Uí Fiachrach septs included Ó Colmáin (O'Colman) and Ó Beolláin (O'Boland), both in the barony of Tireragh, Co. Sligo; Ó Géaráin (O'Gerane), noted in Erris, Co. Mayo;

General Information from the Annals.

Uí Fiachrach Aidne - or "Deiscirt Connacht", of southern Co. Galway, whose territorial boundaries are said to be co-extensive with the Diocese of Kilmacduagh, in the baronies of Kiltartan and part of Dunkellin. Septs included Ó hEidhin (O'Heyne), Ó Cleireach (O'Cleary), Ó Seachnasach (O'Shaughnessy), Ó Cathail (O'Cahill), Mac Giolla Ceallaigh (Kilkelly), ...
The Cenél Guaire of Ui Fiachrach Aidhne included Ó hEidhin, Ó Cleireach, et al. Ó Cleireach (O'Clery) is noted in the Annals as chiefs of Aidhne up through the 10th century. Ó hEidhin (O'Heyne, Hynes) was styled prince of Ui Fiachra Aidhne, the name taken from Eidin, a 10th century chief. They later are said to have shared the lordship of Aidne with their kinsmen, the Ó Seachnasach. O'Donovan's Tribes of Ui Fiachrach describes the extent of Aidhne as bounded on the north by O'Flaherty's country, on the southeast by Moenmoy (i.e. Maonmagh), on the south and southwest by Cenel Fearmaic in Thomond, and on the west by the Burren and Galway Bay.
The Cenél Aedha of Ui Fiachrach Aidhne included Ó Seachnasaigh and Ó Cathail, who are described as a branch of the descendants of Eoghan Aidhne by Tribes of Ui Fiachrach. The Cenél Aedha [na hEchtge] territory is described, by O'Donovan, as the eastern half of the diocese of Kilmacduagh, centered Kinelea in the southeast half of the barony of Kiltarton, in co. Galway. By the 13th century the O Seachnasaigh were said to have supplanted their kinsmen, the Ó Cleireach and Ó Cathail, as a principal sept of the Uí Fiachrach Aidne (McLysaght).
In Tribes of Ui Fiachrach, O'Donovan cites the tribes that inhabited Aidne before the Ui Fiachrach, viz., Ciarraige, Oga Beathra, Tradraige Dubrois, and Caonraige Aird Aidhne.

The Annals cite:

Uí Eachach Muaidhe - the Ui Eachach Muaide (aka Ui Eathach Muidhe) are noted in the Book of Ballymote to have a similar ancestry as the Ui Fiachrach Aidne, that is, in descent from Echach mc. Dathi (aka Nath Í) mc. Fiacrach (a quo Ui Fiachrach). The genealogist O'Hart cites Hy-Eachach Muaidhe as a a district extending along the western bank of the river "Moy," between Ballina and Killala, in co. Mayo. He also cites O'Maolfoghmair, anglicised "Milford", and O'Maolbrennain, anglicised " Mulrennin," as chiefs of Hy-Eachach Muaidhe.

In Tribes of Ui Fiachrach (ed. O'Donovan), it mentions the Clann Laoghaire of Ui Eathach Muaidhe which sprung from Eochaidh's son, Laoghaire; who were comprised of the Ui Creadhchen (Criadhchen), Ui Leanain, and Ui Flaitile (Laitile). The same source mentions Ui Ethach Muaidhe extending from "Ros Serce, in Bredach, in Ui Amalgaidh, to Fionnchaluin and to Fearsad Tresi." Other septs of Ui Eathach Muaidhe included by O'Donovan were the Ui Broduibh, Ui Cremthannáin, Ui Creachain, Ui Dorchaide and Ui Gormiallaigh (ruling families of Partraighe), Ui Maoilaichen and Ui Maoilbreanainn (branches of Ui Fiachrach), and Ui Maelfoghmhair (of Killala),

The Annals cite:

Uí Fiachrach Muaide (or Muirisce) - or "Tuaiscirt Connacht", the Moy River valley of Co. Mayo. The Uí Fiachrach Muaide territory at its widest reach included the baronies of Erris and Tirawley in Co. Mayo, and the barony of Tireragh in Co. Sligo.
A chief sept included Ó Dubhda (O'Dowd), princes at Carn Amalgaidh, near Killala, Co. Mayo. The Ó Caithniadh (O'Canny) sept were noted as chiefs of Erris before being displaced by the Barretts in the 13th century. Other septs also included Ó Cadhain (O'Coyne), Ó Cearnaigh (O'Carney) of Moynulla and Balla, Ó Toghda (O'Towey) of Bredagh, Ó Gaibhtheachain (O'Gaughan) of Calry, the Ó Muireadhaigh (Murrays) of Lagan, and the Ó Lachtna of the two Bacs and of Glenn Nemthinne in Tir-Amhalgaidh [Tirawley], Ui Dubhagain and Clann Firbisigh of the tribes of the two Baic and of Glenn.

Tir Amalgaidh, or Ui Amalgada, was another name for the barony of Tirawly, co. Mayo, where Ó Dubhda was chief. Iorruis was another name for the barony of Erris. Branches of the Ui Amhalgaidh included the Cenél Fedhlimidh Iorruis, the Cenél Aengusa and the Cenél Muireadaigh mic Fergusa. In Tribes of Ui Fiachrach, O'Donovan makes note of the Cenél Fedhlimidh Iorruis la huib Amhalgaidh, comprising the families of Ó Ceallachain, Ó Caithniadh, Mac Coinin, Ó Muimhnecaháin, Mag Fhionain, Ó Gearadhain, Ó Conbóirne. In the same source, the Cenél Aengusa la huib Amhalgaidh comprised the families of Ó Muireadhaigh of the Lacan (or an Lagán), and Ó Radubháin of Gleann an chairn, and the people of Lucht Dúna Finne (Doonfeeny), i.e., Ó Cuinn, Meg Ódhráin, Ó Comhdhan, Ó Duibhlearga, Ó Bearga, Ó Blighe, Ó Duanma or Duanmaigh. It was the Clann Muireadaigh mic Fergusa (e.g. Ó Lachtna, Ó Maelruaidh, and Mac Firbisigh) that held the cantreds of Bac and Glenn Nemhthinne and the half cantred of Bredach according to the Book of Lecan.

Fir Ceara - or Chera or Cera, a branch of the [northern] Ui Fiachrach centered in the barony of Cara, modern county Mayo. Ua Coigligh and Ua Cearnaigh (of Tuath Mhuaighe Fhiondalbha) were noted as septs in this region, their territory named Moynulla and Balla. MacFirbis in his Book of Genealogies describes the Sil Fiachrach comprising the Fir Cheara, Ui Fiacrach Aidhne alias Cénel Guaire, Cineal Aodha na hEchtghe, and Coill Ua Ffiacrach. O'Donovan adds Ui Amhalgaidh Iorruis &c. to this list.

One of the fragmentary Irish annals mentions a Móenach Cera, king of Fir Cera Uí Fiachrach. In Tribes of Ui Fiachrach, and other sources, Cera was the residence of some of the early Christian kings of Connaught, i.e Eoghan Beal, Ailell Ionbhanna, Aodh a Crunmhaol.
In O'Hart's Pedigrees, perhaps taken from O'Dugan's Topographical Poem, he mentions O'Muiredhaigh or O'Murray as a chief of Ceara, as well as a chief of Lagan, a district in the northern part of the barony of Tirawley, in Mayo. He also mentions O'Gormog (modernized O'Gorman) as another chief in Carra.
From an entry in the Irish Annals an early genealogy appears as: Earc (Mac Erca), son of Ailill Molt, son of Dathi (Nathi), son of Fiachraidh, son of Eochaidh Muighmheadhon.

Uí Máine - see Ui Maine.

Uí hMaill - Co. Mayo, the country all around Clew Bay (Umallia, the "Owles"), now known as the baronies of Burrishoole and Murrisk, in co. Mayo. The sept of Ó Máille (O'Malley) were chiefs in this region. Umhall Uachtarach (Upper Owel) was a former name of the Barony of Murrisk; Umall Íochtrach (Lower Owel) was a former name for the barony of Burrishoole. The two baronies were referred to as 'Umhall Ui Mhaille' (territory of the O'Malleys) or the Two Owels.
It is claimed by some that the O'Malley's derived their descent not from Brion, the great ancestor of the Connaught kings, but from his brother Orbsen.
Note: Not to be confused with Ui Mail of Leinster.

Cenél Cairpre [Mor] - (Uí Cairpri) - northern Co. Sligo and northeast Co. Leitrim. The territory of Cairbre, son of Niall of the Nine Hostages, around the 6th century extended from the Drowes west to the Owenmore river in Ballysadare. Duncarbry (Dun Chairbre- Cairbre's Fort) - later a McClancy fort - marks the border of Cairbre's territory on the Drowes, while the Barony of Carbury in North Sligo today reminds us also of where he ruled. Noted chiefs of Cenél Cairpre included O'Mulclohy (Ó Maolchloiche), a name which was later mistranslated to Stone. Cairbre's descendants are said to have also settled in Grandard in the county of Longford. Also see Cairbre Gabra, of co. Longford; and Uí Cairpri Laigen, of co. Kildare.

The annals cite for the general terms Cairpre, Coirpri, et al. :

Calraige - The territory of the Calraighi Móra included parts of eastern Co. Sligo and northwestern Co. Leitrim. Ó hInnreachtaigh were hereditary cheiftains of the Calraighe of Corann. The chiefs of the Calraighe of Loch Gile, along Lough Gill on the Sligo/Leitrim border, included O'Finn, Ó and Cearbhaill (O'Carroll), and remembered in the name of the parish of Calry, barony of Carbury, co. Sligo. The Calraighi Luirg are noted in the Onomasticon Goedelicum in the area of Moylurg, northern co. Roscommon. O'Drean was hereditary chieftain of Calraighe Luirg.

The septs of Ó Mailfhina, Ó Gaibhtheacháin (O'Gaughan), and Ó Floinn are mentioned as chiefs of Calraighe of Magh hEileag, aka Calraige of Maige Muirisc in the barony of Tirawley, Co. Mayo. Their near neighbors included the Calraige of Cuil Cearna, aka Cúli Cernadán, or Coolcarney, represented by Ó Scingin and Ó Rothlain, an area on the border of counties Mayo and Sligo. The term Calraighe Trí Maige appear to apply to the Calraigi groups of this region of Connacht.

A common claim of the various Calraighe septs is to their ancestor, Lugaidh Cal, son of Dáire mac Íréil Glúnmáir mac Conaill Cernaich.

Note: Calraighe, or Calry, is a term used in the midland region of Ireland as well. The Calraige (of Tethba) in western Westmeath and northern Offaly included the Mac Amhalghaidh (MacAwley) clan. The Calraighe an Chaluidh, of Brí Leith, and of Breaghmhaine are noted in this region of the old territory of Tethba. For further reference, see Calraighe of Midhe.

The Annals cite for all Calraige territories:

Conmaicne of Connacht - The Conmaicne were of the older tribes of Connacht. Their lineage is claimed from Conmac, a descendant of Queen Medhbh and Fergus MacRoigh.

The Conmaicne Mara were found in western Galway (e.g. barony of Ballinahinch) and gave their name to modern Connemara.
The territory of Conmaicne Cuile Toladh, centered in Kilmaine barony, County Mayo, was mentioned in the prehistory of Ireland as the battle place of the last Firbolg king of Ireland (quoted at circa 1900 B.C. in the Annals), that is of Eochaidh, son of Erc, who was killed by the invading Tuath de Danaan. In O'Hart's Pedigrees he mentions the name O'Talcharaln, as a chief of Conmaicne Cuile, apparently taking this information from O'Dugan's Topographical Poem.
Another group were referred to as the Conmaicne Críchi Meic Eircce in (Fir Ceara) Ui Fiachrach. Their descent is given through Traech mac Causcraid, or Fráech mac Cúscraigh, depending on source.

The Conmaicne of Magh Réin were found in northwest Connacht (southern Co. Leitrim) in the territory of Bréifne. The Conmaicne Réin were chiefly divided among three clan groupings - Muintir Eolais, Cenel Luachain and Muintir Cearbhallain. Of particular note was the powerful Muintir Anghaile (O'Farrell of Annaly, co. Longford) who are also claimed to descend from the Conmaicne Réin.
The Conmaicne Mide la Cuirccne (of Quirene) were found outside of Connacht, at Cuircne, in the territory of Mide, and were also referred in conjunction with the Conmaicne Bec of the barony of Kilkenny West, co. Westmeath.

An early genealogy is given as:   (Rawlinson)
Cúmscrach (aka Cumascrach) m. Cécht m. Eircc m. Erccdail m. Duib m. Ma Druaid m. Nertai m. Fhernertai m. Cécht m. h-Uisli m. Béirre m. Beidbi m. Luigdech m. Conmaic (a quo Conmaicne) m. Oirbsen Máir (a quo Loch n-Oirbsen).
The early genealogy continues by citing three sons of Cúmscrach, i.e. Fráech (a quo Conmaicne Críchi Meic Eircce), Finer (a quo Conmaicne Réin in Bréifne), and Findchóem (a quo Conmaicne Cúile Talad). It also cites a descendant named Copchass (a quo Conmaicne Mide la Cuirccne).
Conmaicne Cuile Tolad, descended from from Cairid (a quo Síl Cárida), son of Findcaem, son of Cumascrach. One of the septs is described as Cenél Enda, descended from Enna, son of Cairid, son of Findchaemh, son of Cumscrach.
Conmaicne Críchi Meic Eircce - In the Book of Fenagh are described the "3 Conmaicnes", named from three sons of Fraech, son of Cumscrach, i.e. Dubán and Lugna and Cass. They included Cenél Lughna, Cenél cCais and Cenél Dubháin, the latter cited as Conmaicne Dúna Móir in the barony of Dunmore, co. Galway).

Conmaicne - General Information from the Annals,
Conmaicne Mara - or Connemara in western Co. Galway. O'Queally (or O'Kealy) is cited as a chief in Conmaicne Mara prior to the arrival of the O'Flahertys in the 13th century.

The Annals cite:
Conmaicne Cúile Talad - centered in the barony of Kilmaine in southern county Mayo. Lough Corrib in county Galway, also referred to as Loch Oirbsen, was named for an ancestor of the Conmaicne, that is Oirbsen Máir.

Conmaicne Réin - part of Breifne in southern Co. Leitrim. The Conmaicne Réin were chiefly divided among three clan groupings - Muintir Eolais (e.g. MacRannall, Reynolds), Cenel Luachain (e.g. MacDorcy) and Muintir Cearbhallain (e.g. O'Mulvey). The early genealogies cite 'Finer' as the son of Cúscraid macCécht as, a quo Conmaicne Réin of Bréifne. They further cite Cairpre [of the] Conmaicnib Réin, that is Carpre mac Ailella (?Carpri Filed, son of Ailella Máir, in descent from Dáire Barraich mac Cathaír). The O'Rourkes were over-lords in this area for many centuries.

Luigne and Gailenga - Counties Sligo and Mayo. The chiefs of Luigne (barony of Leyney in Co. Sligo) and Gailenga (barony of Gallen in Co. Mayo) included O'Hara (Ó hEaghra) and O'Gara (Ó Gadhra), who often alternated as lords. The Luigne-Gailenga territory comprised the Diocese of Achonry, which would have also included part of the barony of Costello. Also review Corca Fhir Trí for further reference to this region. By the 12th century the O'Garas were lords of the territory of south Luighne, anciently referred to as Gailenga, which was referred to at that time as Sliabh Lugha. The O'Hara's retained the name Luighne for their territory to the north. The O'Garas were expelled into Cuil-Ui-Fionn (barony of Coolavin, Co. Sligo) by the MacSurtains (the Anglo-Norman Jordan family), and became lords of Coolavin, under the MacDermot clan.
Geoffrey Keating cites an ancient genealogy for Luigne and Gailenga thus, "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."
The Book of Ballymote notes the 3 Luigni of Connacht descend from Fland Laigni, son of Cormac Gaileng.
Other groups of Gaileng and Luigni are noted in Mide and Brega, and the same are referenced at this web site on the Breifne page.

The Annals cite:

Masraige - part of Breifne in northwest Co. Cavan, named for an early people of Magh Slecht. The sept of MacGovern or Magauran (Mag Shamhradhain) were cited as chiefs in the barony of Tullyhaw (Teallach Eochaidh) in northwest Co. Cavan. The MacTiernan or MacKeirnan (Mac T[h]ighearnáin) sept are noted in the nearby barony of Tullyhunco (Tellach Donnchadha).

The Annals cite:

Information on the Delbna and the Sogain is located at the Ui Maine page.

Clan Tomaltaigh - The namesake for the clan may have been Tomaltach, an 8th century ancestor of the Siol Murray kings of Connaught. The MacGeraghty (originally Ó Roduibh) sept were chiefs of Muintir Ródhuibh, and of Clan Tomaltiagh situated in the barony of Roscommon, County Roscommon. The Kilkenny Journal of Archaeology describes Clann Tomaltiagh centered in the parish of Baslick, near Ballintubber, co. Roscommon. Up to the 13th century, Mac Aireachtiagh (MacGeraghty) was head of one of the four royal chiefdoms of Siol Murray under the O'Conors, until some were driven into counties Mayo and Sligo by the encroachment of the Normans (e.g. Burkes).

The Annals cite:

Corco Achlann - along with Cenel Dobtha (or Doohy Hanley) and Tir Briuin na Sinna comprised the Three Tuathas area of northern co. Roscommon. The territory lay between the River Owenure and the River Scramogue, both of which flow into the River Shannon. Mac Branáin (MacBranan), an Uí Briuin sept, were noted chiefs of Corca Achlann cited in the annals from 1159 to 1488. Ó Maoil Mhicil (O'Mulvihil) is noted of the same stock as MacBranan, and also cited as chiefs of Corca Sheachlainn, or Corcachlann. The territory is described in Colgan's Trias Thaumaturga between Tiroilell and Mons Bagna, and also described in O'Flaherty's Ogygia between Tír Ailello (Tirerrill) on the north and Sliabh Bagna (Slievebaune, in east co. Roscommon) on the south.

The Corco Ochlann, or Cenel Maic Ercae, are mentioned in a late 7th century text by Tírechán. The later Vita Tripartita says of them, "The race of Macc Ercae is the mightiest and firmest among the Connachta, but they do not rule like over-kings." Some historians believe the Corco Achlann acquired a spurious Uí Briúin Connacht pedigree as they later became known as the Uí Briúin Sinna, named for their territory along the river Shannon.

The Annals cite:

Uí Briúin na Sionna - O'Monaghan, descendants of O'Manachain of 866 AD, were chiefs of this sept in the barony of Ballintober, Co. Roscommon, until the year 1249. This was one of three districts in a region of North Roscommon known as the Tri Tuathas (three countries) stretching from Lanesboro in the south to Jamestown in the north; on the bank of the Shannan (na Sinna). The O'Beirne sept, allied with the MacDermotts, displaced the O'Monaghans at that time when the territory, called "Tir Briuin na Sinnan", was between Elphin and Gorestown on the Co. Roscommon side of the Shannon.

The Annals cite:

Cenel Dobtha - Cenel Dofa or Doohy Hanly, comprised one of the Three Tuathas of northern Roscommon, was held by the Ó hAinle (O'Hanly) sept who were chiefs of Cenel Dobtha. In O'Donovan's comments in Topographical Poems of O'Dugan and O'Heerin, he notes notes Cenel Doffa mic Aengusa, now Doohy-Hanly in Roscommon, comprising the parishes of Kilglass, Termonbarry, Cloontuskert and the east half of the parish of Lissonuffy.

The Annals cite:

Clann Cathail and Clan Connor - Ó Maoilbreannain (Mulrennan) is noted as a sept of Clan Cathail, chief of Clanconnor (in Castlereagh barony). Ó Flannágain (O'Flanagan) is listed as a chief of Clan Cathail, with territory between Mantua and Elphin. Ó Mughróin (O'Moran) is cited as a chief of Clann Cathail, as head of a powerful family seated at Ballintober in Co. Roscommon. Ó Mughráin (O'Moran) is noted early in Co. Galway as chief of Criffon, in the barony of Killian, Roscommon and part of the barony of Ballymoe, Galway.

Clann Cathail is named from Cathal, the son of Muireadhach Muilleathan, who lived in the late 7th/8th century. O'Donovan describes the territory of Clann Cathail (the O Flanagan of Mag n-Aoi in Roscommon) comprising the parishes of Kilmacumshy, Kilcorkey, Shankill, and parts of the parishes of Creeve and Elphin. This was on the borders of the baronies of Roscommon, Castlereagh and Frenchpark.

The Annals cite:

Partraige , or Partry, was an area in County Mayo, roughly west and north of Lough Mask, around the barony of Carra and containing the Partry Mountains. Septs said to originate in this area includeÓ Cadhain (O'Coyne), Ó Dorchaidhe (O'Dorcey or Darcy), Ó Goirmghialla, (O'Gormley), Ó Ciaragain (O'Kerrigan) and Ó Tighearnaigh (O'Tierney). In Leabhar na gCeart, as well as O'Flaherty's Ogygia, claims they were a Damnonian tribe which held Partrige Cera in the barony of Kilmaine; and Partrige Locha, in which are Cong and the field of the first battle of Moytura; and Partrige which extends from Sliabh Patraig to Loch Orbsen or Loch Corrib.
In Tribes of Ui Fiachrach, O'Donovan mentions the Ui Dorchaide and Ui Gormiallaigh as ruling families of Partraighe, and as branches of the Ui Echahc Muaidhe. O'Hart (Pedigrees) also mentions O'Gairmiallaigh or O'Garvaly, and O'Dorchaidhe or O'Dorchy, as chiefs of Partraigh or Partry.

The Annals cite for the terms Partry and Carra:

Fir Domnand - the men of (Irrus) Domnann in the northwest of modern county Mayo. They are speculated to be related to a tribe of Firbolgs, usually called Damnonii, situated in Leinster [Annals of Clonmacnois]. The tribes of Galion and Domnand, alias Laigin, as said in Táin bó Cualnge. Tuath Fer n-domnann is described in Cera (in Erris), in Ui Amalgada and in Ui Fiachra Tuaiscirt, in the Book of Ballymote and Book of Lecan. The Gamanrad lived in Irrus Domnann (about the barony of Erris in co. Mayo) according to the Táin Bó Fraich. The Book of Lecan notes Fir Domnand was located in the northwest of Mayo; in Crích Olnecmacht.

Note: The Celtic tribes of Damnonii and Dumnonii of Britain were located in Scotland and Cornwall, respectively.

The Grecraige (Graicraigi, or Gregraighe) - were noted as a Firbolg tribe that inhabited much of the western part of present day County Sligo between Loch Gara and the Ox mountains. The placename Foibhren is cited in the annals. The tribe of the Crecraige (Cregraigi) was said to settle about the barony of Coolavin, county Sligo, and in the adjacent part of county Roscommon. The Book of Lecan describes the Grecraige as an Aitheachthuath (unfree, or tribute-paying tribe) in Luigni Connacht, about Loch Deichead, the Corand, and in Bearnus Tiri Ailella as far as Mag Tuireadh.

The Annals cite for the term Graicrighe:

Corca Fhir Trí - Corca-Firthri, the people of the barony of Gallen (Gailenga), co. Mayo; and the baronies of Leyney (Luigne) and Corran in co. Sligo; as cited in Onomasticon Goedelicum. Citing from the annals, a sept referenced as Ui Dobhailen (O'Devlin or perhaps O'Dolan) is noted with connections to Luighne (Connacht) and the people of Corca Fir Thrí. MacLysaght states that O'Devlin is derived from the Irish O Doibhilin, a sept located in the barony of Corran, County Sligo, matching to the reference of Luighne and Gailenga in the Annals (below). He also notes the surname O'Dolan deriving from the Irish O Dobhailen, further noting this sept in Ui Maine country.

The Annals cite for the term Corco Fir Trí:

The Ciarraige Áei (Clann Ceithearnaigh) occupied an area near ancient Cruachu on the plain of Magh nAí in central co. Roscomon (near Castlereagh). To the northwest were the Ciarraige Airtig (aka Airtech) on the plain of Magh nAirtig in northwest co. Roscommon (parish of Tibohine). To the west, across the modern co. Mayo border, were the Ciarraige Locha na Áirne. They likely formed part of a single territory before being fragmented by the Ui Briuin Ai in the 8th and 9th centuries. The Corco Cullu, an aithech-thuath (unfree tribe) of the Ciarraige are described as a major population group in Mag nAí at the time of the Ui Briuin acendancy in the 7th century, one of them noted in the annals slaying Ragallach, son of Uatu, (Ui Briuin) king of Connacht in 648.

The sept known as Ó Céirín (O'Kieran, Kearns, Keherny) were in early times in possession of the greater part of the modern barony of Costello, eastern co. Mayo, anciently part of a territory known as Ciarraighe Locha na nÁirne, a.k.a. Ciarraige na nAirneadh, Ciarraige Uachtair, or Ciarraige Iartharach. They were also associated with the neighboring barony of Clanmorris.

The Ciarraige Aidne (sometimes given as or near Óga Beathra) were noted in the southern part of Connacht. They are mentioned in Tribes of Ui Fiachrach (ed. O'Donovan) as one of the tribes inhabiting Aidne before the Ui Fiachrach.

Their ancestry is claimed to originate with an individual named Ciar, who was a common ancestor, and namesake, for four tribal groups referred to as the Ciarraige Luachra, Ciarraige Cuirche, Ciarraige Áei, and Ciarraige Choinnend. The Book of Lecan provides the following Ciarraige names: Ciarraige Luachra, Ciarraige Chuirci, Ciarraige Aei, Ciarraige Choincind, Ciarraige Trimaige, Ciarraige Lacha are nAirnead, and Ciarraige Broengair.

The Annals cite for the Ciarraighe of Connacht:

Moylurg, Airtech, and Tir Tuathail - Moylurg (Magh Luirg) was an area in the north of Co. Rosscommon roughly corresponding to the baronies of Boyle and Frenchpark. The descendants of Mhaoil Ruanaidh (brother of Conor, a quo O'Conor) held sway in this vicinity, as princes of Moylurg. They are first represented as Uí Mhaoil Ruanaidh and then as Mac Diarmata (MacDermot, et al). The influence of the Mac Dermots is reflected in the entries in the Annals (see below).
After being dispossessed of their ancestral lands, the MacDermotts were later to become princes of Coolavin, as successors to the O'Garas (of Gailenga), the former lords of Coolavin, co. Sligo.
Cited by Edward MacLysaght, the Mac Riabhaigh sept (e.g. MacGreevy) were lords of Moylurg until the early 13th Century, becoming tributary to the MacDermots. Fir Scéne, a tribe name of Mac Riabhaigh, whose chief seat was on Loch Cé before the McDermots seized it.
