Background on Uí Maine

Ancient Ui Maine

Uí Maine, or Hy Many, was centered in eastern Co. Galway and southern Roscommon. John O'Donovan in his work the Tribes and Customs of Hy Maine states the ancient territory of Úi Maini comprised; in county Roscommon the baronies of Ballymoe, Ballintober South, Athlone and Moycarn; and in county Galway the baronies of Ballymoe, Tiaquin, Killian, Kilconnell, Clonmacnowen, Longford, Leitrim, Loughrea, and parts of Dunkellin and Athenry; and in county Clare, part of Tulla Upper.; and in King's Co. (co. Offaly) the parish of Lusmagh. The Annals of Ireland describes Ath na ríogh, Athenry in co. Galway, as the ford where the territories of Aidne, Ui Maine, and Ui Briúin Seola meet.

About the 5th century, a northern tribe moved into East Galway; they were said to be descended from Colla dá Críoch (one of the Three Collas). They occupied an area around Ballinasloe, and Creagh supposedly takes its name from them. One of their chieftains was called Máine Mór, from whom are the descended tribes of Uí Máine, aka Hy Many. Among the Úi Maine dwelt the Sogain, a Cruthin tribe, the Delbna, the Dal naDruithne who are believed to be of the mythic Tuatha Dé Danann Celts, as well as other tribal groupings who came under tribute of the Uí Maine dynasts. Like many areas of medieval Ireland the territory of Ui Maine contained a variety of septs and tribal groups who are often inter-connected by actual or synthethic genealogies.

According to the historian O'Rahilly, the Uí Maine were pre-Milesian Celts who were later given a fictitious Milesian pedigree showing them descended from Maine Mor, son of Eochu, in descent from Conn Cétchathach (Conn of the Hundred Battles). Among the variant genealogies is also cited Maine, son of Niall [of the Nine Hostages], a quo Úi Maine & Fir Thethba & Breacraighe. It is interesting to note that the Úi Maine of Teathbha were early neighbors of the Úi Maine of Connacht, separated by the river Shannon. Francis Byrne in his Irish Kings and High-Kings cites the Úi Maine of Connacht held territory further north in co. Roscommon in the early years of their settlement. The Ui Maine of Connacht were also neighbors across the river from the Breacraighe. Were the two Úi Maine possibly a connected tribal group, separated by later genealogies?

Other genealogies exist for different septs with the same name. These include Uí Maine genealogy who are descended from Óengus Dub, grandson of Cathaír Mór, of the Ua Failge sept of Leinster.

The O'Kellys, O'Donnellans and O'Maddens were prominent among the septs of the Uí Máine of southeast Connacht. The O'Kellys (Ó Ceallaigh) were over-lords in the territory of Hy Many, their eponymous ancestor cited as Ceallach, son of Finnachta, a chief of the Hy Many people about 874 A.D. The O'Donnellans claim descent from Domhállan, lord of Clan Breasail. The O'Maddens (Ó Madadháin) held territory in Co. Galway next to the Shannon and extending over the river in Offaly, their surname derived from an ancestor given as Madúdhan, a chieftain of Síl n-Anmcadha who was slain in 1008.

Other septs within the traditional region of Uí Máine included Ó Concheanainn (O'Concannon), lords of Uí Diarmada near Kilkerrin, Co. Galway; Ó Cobhthaigh (O'Coffey), a branch of the O'Maddens; Ó Neachtain (O'Naghten), chiefs near Loughrea and later of the Fews (Athlone); Ó Maolalaidh (O'Mulally or Lally), of the same stock as the O'Naghtens; Mac Eochaidh (MacKeogh), lords of Magh Finn (Moyfinn, Athlone); Ó Roduibh (Mac Geraghty), one of the four royal chiefs under O'Conor; Ó Fathaigh (O'Fahy), whose territory came to be known Pobal Mhuintir ui Fhathaigh; Ó Dúnadhaigh (O'Downey), chiefs of Sil Anmchada prior to the O'Maddens; Ó Dubhagain (O'Dugan), though not of the same stock as the O'Kellys; Ó Cionnaoith (O'Kenny), of the same stock as O'Madden; Ó Muireadhaigh (O'Murry) of the barony of Athlone; Ó Treasaigh (O'Tracy), akin to the O'Maddens; Ua Braonain of Sil Anmchadha, closely related to the O'Maddens were located in the barony of Longford in County Galway; Ó Conghalaigh (O'Connolly), of the same stock as O'Madden; Ó Conraoi (O'Conry) of Hy Many; Mic Uallacháin (Mac Cuolahan) of Garrycastle, Co. Offaly, noted as chiefs of Muintir Cionaetha; O'Draighneain (O'Drennan) of the Sil Anmchadha group in the barony of Longford; O Dobhailen (Dolan) of Clommacowen, Co. Galway and Athlone, Co. Roscommon; Ó Fallamhain (O'Fallon), chiefs of Clan Uadach; Ui Longargáin of Ballynabanaby (parish of Kilgerril, barony of Kilconnel), described as Harpers of the Hi Maine; ...

Following the coming of the Normans beginning in the 13th century, a portion of ancient Ui Maine later became known as the district of Clanricarde, named for a branch of the Burke family. This included much of the baronies of Loughrea, Kiltartan, Clare, Dunkellin, Athenry and Leitrim, in co. Galway, according to O'Donovan.

Síl n-Anmcadha

Ó Dúnadhaigh (O'Downey) were chiefs of Sil Anmchada up to the 11th/12th? century, prior to the rise of the Ó Madudháin (O'Madden) sept. The Ua Braonain of Siol Anmchadha, closely related to the O'Maddens were located in the barony of Longford, county Galway. As such they were a branch of the Uí Maine. The eponymous ancestor of the O'Maddens is given as Madúdhan, a chieftain of Síl n-Anmcadha who was slain in 1008.

An early genealogy (in O'Clery) is cited as:

Ui Diarmada

Ó Concheannainn (O'Concannon), said to be a sept of the Ui Maine? (by McLysaght), were lords of Ui Diarmada in the parish of Kilkerrin, County Galway, from the 11th to the 15th centuries. They claim descent from Cú Chenand, son of Tadhc mac Muirchertaigh, who was killed about 991.
The genealogies of the Book of Ballymote place their descent through the Sil Muiredaigh of Uí Briúin, under the heading Genelach Diarmata Find mc. Tomaltaig. A lineage there is cited as Murgius (of 1037), son of Uatu, son of Cú Cenand, son of Tadg, son of Muircertach, son of Ailill, son of Uatu, son of Datláech, son of Diarmaid Find, son of Tomaltach, son of Murgal, son of Indrachtach, son of Muiredach muillethan.

Note: Not to be confused with O'Cairellain of Clann-Diarmada in northern Ireland, or with Mac Diarmada, kings of Magh-Luirg (Moylurg).

Ui Fiachrach Finn - descended from Fiachra Finn, grandson of Maine Mór (a quo Ui Maine), this tribal name was noted in Moenmoy, county Roscommon (Tribes and Customs of Hy Maine, ed. O'Donovan). O Neachtain (O'Naghten, O'Naughton) and O Maolalaidh (O'Mullally) were noted as chiefs in this region prior to the Anglo-Norman invasion.

John O'Dubhagain in his Topographical Poems cites the sept of "O hEirc, over Ui-Fiachrach Finn," a reference to the territories of Airghialla (northern Ireland). The sept of O hEirc, chiefs of Hy-Fiachra Finn, were noted by O'Hart in the barony of Massarene, modern co. Antrim. The Leabhar na gCeart cites Ui Fiachrach Finn in and around the parish of Ardstraw in county Tyrone, an area which has been equated with the Uí Fiachrach Arda Srátha (Ardstraw).
There are other references to Ui Fiachrach in the Airgialla region, for example the Síl Ciarain of Ui Fiachrach are noted of Dún Da Én in Dail Araide and Síl Ciarain Ua nEchach of Airthir in Ulster (Book of Lecan).

Maenmagh - aka Maonmag or Moenmoy, a territory round Loch Reagh, co. Galway. Maonmuighe or Maenmoy is described as an extensive plain comprising a great part of the present baronies of Loughrea and Leitrim in the county Galway. O Neachtain (O'Naghten, O'Naughton) and O Maolalaidh (O'Mullally) were noted as chiefs in this region prior to the Anglo-Norman invasion (see above).

The Cenél Cormaic were also noted in Maenmaigh (descended from Cormac, son of Eoghan, son of Niall?). The genealogy of Ui Corpmaic Maenmhuighe is cited by O'Clery, in descent from corpmaic m Cremhthainn m Bresail m Maine mhoir (a quo Ui Maine). O'Hart cites O'Donchadha, or O'Donoghoe, were chiefs of Clan Cormaic, a district in Maenmoy in Galway.

Clann Diarmada and Clann Aedhagáin
MacEideadhain or Mac Aodhagain (anglicised "MacEgan") were chiefs of Clan Diarmada, a district in the barony of Leitrim, county Galway; and had a castle at Dun Doighre, now "Duniry." The MacEgans were Brehons in Connaught, and also in Ormond; and many of them eminent literary men. The Mac Egans supplied hereditary Brehons to different parts of Ireland. O'Hart mentions the sept of O'Connaill or O'Connell, chiefs of the territory from the river Grian (or Graney), on the borders of Clare (barony of Upper Tulla), to the plain of Maenmoy: comprising parts of the barony of Leitrim in Galway, and of Tullagh in Clare. These O'Connells and the MacEgans were marshals of the forces to the O'Kellys, princes of Hy-Maine; and of the same descent as the O'Kellys, namely that of the Clan Colla.

Clann Flaitheamhail - a district in the barony of Moycarn, county Roscommon, its chief was Mac Gilli Enáin (Book of Lecan). O'Hart states the MacGiolla Fionnagain or O'Finnegan, and the Ó Cionnaoith or O'Kenny, were chiefs of Clan Iaitheamhaim or Flaitheamhain, called also Muintir Cionaith, a district in the barony of Moycarnon, county Roscommon.

The Annals cite:

Clann Connmaigh and Clann Murchadha - O Fínnachta (O'Finaghty) were chiefs of Clan Connmaigh and of Clan Murchada, districts in the two half baronies of Ballymoe in the counties of Galway and Roscommon. Clanconow, alias Clanconway, is described by O'Donovan as west of the river, a branch of the O Finaghtys. Hennessy gives Clann Murchadha on the east of the river Suck. O'Finaghty of Clan Conway, had their castle at Dunamon (Caislén Dúin Imgáin), near the river Suck, in the county Roscommon. O'Dugan makes note of their two chiefs in the Poems, and cites Finaghty of "Clan Murrogh of the Champions;" and Finaghty of the "Clan Conway."

The O'Finaghtys were noted by O'Hart as a branch of Clan Colla, as were the Ui Maine. The historian O'Dononvan notes the Ó Fionachta (O'Finaghty) were of the same stock as the O'Connors of Sil Murray, who at one time were senior to them. Dr. A. Moore states that there was also an Ui Maine sept of O'Finaghty. The Annals of Tigernach give Clann Conmaig as a sub-division of Síl Muiredaig, the territory giving tribute to the kings of Connacht. The Mac Davey Burkes were later lords of Clanconway.

An early genealogy of Clann Murchadha:

Clan Breasail - Chiefs of Clan Breasail, a district in the barony of Leitrim, county Galway, are identified by O'Hart as O'Domhnallain or O'Donnelan. McLysaght places them with Ballydonnellan, a district between Ballinasloe and Loughrea. They claim descent from Domhnallán, a lord of Clan Breasail, and were chiefly known as ollavs or poets. The Book of Lecan cites Muinter Domnalláin, in Húib Maine, as an alias for Clan Breasil.
Note: Clan Breasail is not to be confused with the Uí Bresail of Armagh.

The Annals cite:

Note: There was also an apparently unrelated sept of Ua Fallamhain (O'Fallon of Crich na Cetach) centered near the barony of Warrenstown, county Offaly. Perhaps related to these were the people of Caille Fallamhain, a territory noted near the barony of Moygoish, in the north of county Westmeath, with Ua Lorcáin and Ua Clérchéin cited as chiefs in the 11th century.

An early genealogy of Clann Uadach:

MacConry (King) of Moycullen are cited as chiefs of Dealbhna Thire Dá Locha (of the Two Lakes), though not located in Ui Maine.
There were also Delbna territories in Westmeath and Meath, i.e. Delbna Mor, Delbna Bec and Delbna bEthra. For reference on these, see Mide and Brega.

Sogaine - of modern counties Galway and Mayo, centered about the barony of Tiaquin. O'Mainnin, O'Mannin, O'Mannion, or O'Manning, were cited as chiefs of Sodhan (Sogain). The other chiefs given by O'Dugan on the "Six Sodhans" were Mac-an-Bhaird (MacWard or Ward); O'Sgurra (Scurry); O'Lennain (Lennon); O'Casain (Cashin); O'Gialla or O'Giallain (rendered Gilly, and Geallan); and O'Maigin or Magin (MacGing or Ging).

According to the "Book of Lecan" the Sogain were descended from Sodain (Soghan Sal-bhuidhe), the son of Fiachra Araidh, King of Ulster about 240 AD. It would appear that they came to Galway about the 3rd century as they were well established there by St. Patrick's time. They occupied an area which, according to the Book of Uí Máine, stretched from the river Clare in the west to the river Suck in the east and from the river Shivern in the north to the Raford river in the south. This area was known as Mag Sencheineoil, or the plain of the old inhabitants.
Onomasticon Goedelicum cites that the Ui Echach Coba, Ui Meith Macha and Conaille Murthemne are of the same stock as Sogain. They were members of Clann Conaill Cernaich, i.e. Dál n-Araide & Úi Echach Ulad & Conaille Murthemni & Laígsi Laigen & na secht Sogain.

Among the Ui Máine dwelt the Sogain, a Cruithin (Pict) tribe, and the Dal naDruithne believed to be Tuatha De Danann Celts. According to Tribes and Customs of Hy Maine (ed. O'Donovan), Ó Mannáin, chief of the 6 Sogain, had his chief seat at Menlach O Mainnin near Castle Blakeney, the six Sogain noted as Cenél Fergna, Cenél nDomangein, Cenél Luchta, Cenél Rechta, Cenél Tréna, and Cenél Deigeille. Ballydugan and Muine Casáin (the seat of Mac Ward) are included within the territory of the Sogain.
The Book of Uí Máine also states that the Sogain comprised six kindred branches: Cineál Reachta, Tréana, Cineál Luchta, Cineál Fergna, Cineál Domangéin and Cineál Deigeille.

The Annals cite:

U803, A skirmish between the Sogain and the sept of Maenmag, in which many were slain.

Dál nDruithne
The Dál nDruithne are described in the Book of Ui Maine as a branch of the Catraighe (an ancient tribal group) who were centered by the river Suca (Suck) in Hy Maine. It is also referred to as Druithnia, a quo Dál nDruithni in Connacht. The Book of Lecan describes Dál nDruithne as a sub-division of Ui Maine; in Maenmagh in Connacht, and that they are descended from Duach, son of Daimin (in the line of the three Collas).

The Book of Ui Maine describes some of the early tribes of the Catraige Suca (on both sides of the river Suck) as the Corcho Moncho, Dál nDruithne, Fir Muighe Seincineoil, and Muinnter Tuaighe Milchon.

O'Hart cites O'Docomlain, chiefs of Eidhnigh; and O'Gabhrain or O'Gauran, chiefs of Dal Druithne, districts about Loughrea.

Cremthann (Crumthann, Cruffon, Criffon)
Cruffon, a district containing the barony of Killian and large part of the barony of Ballymoe in co. Galway. O'Hart describes the three chiefs of Crumthan or Cruffan, as O'Cathail (Cahill), O'Mughroin (Moran), and O'Maolruanaidh (Mulrooney or Rooney). Tribes and Customs of Hy Maine cites the Ui Chrumthainn were of Crumthann, aka Cruffon, in Ui Maine. Clann Cremthaind, a sept of Ui Maine, descended from Crimthann Cael, 4th from Maine mór.

Note: An O'Mughroin sept is cited as a chief of Clann Cathail in Connacht. A sept of Ua Cathail were lords of Eóganacht Locha Léin in Munster.

O'Hart notes that Mac Eochaidh (MacKeogh or Keogh) was a branch of the O'Kelly princes of Hy-Maine, and were cited as chiefs of Omhanach, now "Onagh," in the parish of Taghmaconnell, barony of Athlone, county Roscommon. Other sources note they were lords of Magh Finn and their territory of Moyfinn in the barony of Athlone, Co. Roscommon, was long known as Keogh's Country.
In Tribes and Customs of Hy Maine, it notes O'Mailbrigdi was chief of Bredach (Brétach, mBretaigh), alias Mag Finn (Findmag), alias Keogh's country; in the barony of Athlone, co. Roscommon. The same source cites the Clann Eochada of Maige Finn, Keogh's country. O'Donovans Tribes of Ui Fiachrach notes that Mac Eochadha or Mac Keogh were inaugurated at Dún Caillighe Béirre.

In the Book of Ui Maine it mentions the King of Caladh "owned from Móinín Raideach [Móin Inraidech] to Cluain Tuaisceart na Sinda." O'Hart cites that O'Laodog or O'Laodhaigh, anglicised "O'Leahy," were chiefs of Caladh in this barony. McLysaght makes note of the sept of Lahiff (sometimes O'Lahy) in this general and gives their Gaelic name as O Laithimh.
