Ui Eathach Cobha in County Down

Ui Eathach Cobha is an ancient territory in modern counties Down and Armagh, corresponding to the modern baronies of Iveagh in county Down and the small part of the diocese of Dromore that lies in county Armagh. (For a map and brief description of the diocese of Dromore, go to The Dioceses of Ireland—Territorial History.) The name Iveagh, and of the people occupying the territory, came from Eochaidh Cobha. According to the Annals of the Four Masters, Eochaidh Cobha was a son of Connla, who was son of Caelbhadh, Irish Kings #123, who ruled in 357 A.D. The Annals of Ulster and the Annals of Tigernach agree. Various genealogies, however, make Eochaidh Cobha a brother of Caelbhadh, and name both Eochaidh Cobha and Caelbhadh as sons of Crunn Badhrai, king of Ulster. The Keating Genealogies even make the "Eochaidh, from whom Ui Eachach of Ulster are called," the father of Crunn Badhrai. The table of the Lords of Ui Eathach I have presented below, and similar tables in this website, are designed to help sort out such puzzles.

In preparing this table, I have combed the Annals of the Four Masters, the Annals of Ulster, the Annals of Tigernach, and the Genealogies from Rawlinson B 502, in the Celt Corpus of Electronic Texts, on the website of the University College Cork. I have also examined the Laud 610 Genealogies and Tribal Histories and The Keating Genealogies on the Clann McLaughlin web page. I have also consulted Irish Kings and High-Kings (1973) by Francis John Byrne. I refer to these sources in the table. When there are inconsistencies between the pedigrees shown in the Annals and those shown by different genealogies, I usually adopt the pedigree shown in the Annals.


 Table of Contents 


Ui Eathach Cobha—Ui Eachdach Uladh—Ui Eachach

The index to John O'Donovan's edition of the Annals of the Four Masters treats as interchangeable the terms Ui Eathach Cobha and Ui Eachdach Uladh—the name of an ancient tribe in county Down. The Annals of the Four Masters also use the term Ui Eachdhach Cobha (e.g. M771.14) or simply Cobha (e.g. M879.9). The Annals of Ulster use the term Ui Eachach for the same sept. The Annals of Tigernach use Ui Eachach Ulad. Byrne, in his Irish Kings and High-Kings, calls them the Ui Ecach Cobo.

The Annals of the Four Masters also use the name Ui Eathach Uladh to describe the same tribe:

M547.2 The King of Ulidia, Eochaidh, son of Connla, son of Caelbhadh, son of Crunn Badhrai, died.

O'Donovan notes that the Annals of Ulster more correctly place this death in 552. and quotes the Annals of Clonmanoise: "A.D. 550. Ahagh Mac Conlay, King of Ulster, of whom Ivehagh is called."

O'Donovan also quotes a note from an edition of the Annals of Ulster: "Eochaidh, son of Connla—'A.D.552 Mors Eachach mic Conleid, ri Ulad a quo omnes I-Eachach-Ulad.'—Ann. Ult., Clarendon, tom 49." [death of Eachach, son of Conleid, from whom come all the Ui Eachach Uladh].

Byrne, in his table of the Kings of Ulaid (Cruthin), Appendix II, page 287, gives 553 as the year of the death of Eochaid, son of Condlae, son of Coelub, son of Crond Ba Drui. He says the Ui Echach Cobo derive their name from Echu, a great-uncle of this Eochaid, and a brother of Coelub and a son of Crond Ba Drui.

M548.10 The death of Eochaidh, son of Connlo, King of Ulidia, from whom are the Ui Eathach Uladh.—Tighernach.

As a footnote to this entry, O'Donovan defines Ui-Eachach-Uladh: "i.e. nepotes Eochidii Ulidiae. These were the inhabitants of the baronies of Iveagh, in the County of Down—See Ecclesiastical Antiquities of Down and Connor and Dromore, by the Rev. Wm. Reeves, M.B., pp. 348 to 352." He also notes: "The Editor shall henceforward use Ulidia for Uladh, when it denotes the portion of the province of Uladh, or Ulster, lying east of the River Bann, and Gleann-Righe, to distinguish it from the whole province."

The double entries of the same death in the Annals of Ulster show the usual differences in spellings and years:

U553.1 Death of Eochu son of Conlaed i.e. king of Ulaid, in whom the Uí Echach Ulad originate.

U558.4 Death of Eochu son of Conlaed, king of Ulaid.

[Double entries, such as these multiple reports of the death of the same person in different years, are not unusual in the Annals of the Four Masters.]

The Annals of the Four Masters sometimes use the term Ui Eachdhach to describe the Ui Eathach Cobha; for example,

M689.3 Fearghus, son of Lodan, King of Ulidia, was slain by the Ui Eachdhach people of Iveagh.

The Annals of the Four Masters sometimes refer to the Ui Eathach Cobha simply as the Iveagh (e.g. M1179.4, M1383.8).

The annals of Ulster uses the phrase "h-Ui Eachach Ulad" to describe the same tribe. For example, "T553.1 Bass Eachach maic Connlai, rig Ulad, a quo h-Ui Eachach Ulad natí sunt. [The death of Eachach, son of Connlaigh, king of Ulidia, from who are the tribe of h-Ui Eachach Ulad.]


Eochaidh Cobha not descended from Colla da Chrioch

The Eochaidh who, according to the genealogists, gave his name to the Ui Eathach Cobha, or Iveagh, is not the same Eochaidh that John O'Hart, in his Irish Pedigrees or the Root and Stem of the Irish Nation, says was the progenitor of the McGoughs—or at least some of the McGoughs. O'Hart's Eochaidh was a great grandson of Colla da Chrioch (son of Felim,. son of Fiachra Cassan, son of Colla da Chrioch), the first king of Oriel. See the discussion and tables on my page: Colla da Chrioch, First King of Oriel.

Eochaidh (or Echach) Coba (or Eocha Cobu) was the son (or perhaps great-grandson) of Crond Badruí (or Cruind Ba Drui or Crunn Badhrai), the 47th King of Ulster, in the line of Fiacha Araidhe, the 37th King of Ulster. See the table on my page: Kings of Ulster—to Colla da Chrioch. Other sources say that Eocha Coba was the son of Connlo, son of Caelbhadh, son of Crunn Badhrai. See the table below. Eochaidh Coba was a king of Ulster who died in 553.

Maps of County Down

The ancient territory of the Ui Eathach Cobha is located in what are now the baronies of Iveagh in county Down plus the small part of the diocese of Dromore that lies in county Armagh. Today's Iveagh included four baronies, all named Iveagh: Lower—lower half, Lower—upper half, Upper—lower half, and Upper—upper half. See the Baronies of Ireland on Ireland's History in Maps. The Iveagh baronies comprise roughly the northern two-thirds of the western half of county Down, and border on county Armagh to the west. PRONI has published a color-coded map of the Baronies of Northern Ireland that allows the viewing of the baronies in each county, including county Down.

A map of the barony of Kinealerty (Kinelarty) of 1656, from the survey of in county Down by Sir William Petty, shows the barony of "Evagh Upper" on the right and "Lower Evagh" at the bottom. "Upper Evagh" is shown at the bottom of a map of the parish of Magherehowlet (Magherehamlet) and "Lower Evagh Barony" is shown at the bottom of a map of the parish of Magheredril (Magheredroll), both from the same survey. These and other old maps of county Down are published on the website McCartan of Kinelarty County Down. An explanation of the place names used in the maps on the McCartan website says that the current name of Evagh is the barony of Iveagh and the Irish derivation is Uibh Eachach, which means "descendants of Echu."

The seventy civil parishes of county Down are displayed on a map published by the Ulster Historical Foundation. A map showing the major towns of county Down has been published by, Ireland's national tourism service. Descriptions, and often photographs, of the towns shown on the map are available on the website..

In the references below, where possible, I give the name of a town, parish, or barony, to help locate the area being mentioned.


Territory of Ui Eathach Cobha

Here are excerpts from a discussion on the web page, Background on Uladh, which includes a list of the ancient kings and lords of Uladh (Ulidia):

"An ancient territory in Ulster, referred to in these texts as Uladh, Ulaid and Ulidia, was noted to be the home of the Ulaid and the Cruithne tribes, e.g. the Dál Fiatach, Dál Araidhe, Uí Eathach Cobha, Conaille Muirtheimhne, Leth Cathail, and the Dál Riada, among others. An ancient cultural center for the Ulaid was at Emhain Macha [Navan, two miles west of the city of Armagh], in modern County Armagh, before being driven east by the incursion of the three Collas. A later center for the Dál Fiatach was established at or near modern Downpatrick in County Down.

"The ancient Uladh genealogies cite Clann Conaill Cernaich, of the line of Ir, a quo Dál n-Araide, and the Úi Echach Ulad, and the Conaille Murthemni, and the Laígsi Laigen (of Leinster), and the Sogaine (of Connacht). The Dál Fiatach (Clan Con Ruí, probably named from Fiatach Finn) and the Dál Riata (named from Cairbre Riada) are cited in the line of Heremon.

"The Uí Eochadha, later anglicized as Haughey, O'Hoey and Hoy, were noted chiefs of Uladh (Ulster) in the 10th century. The ancestors of the Uí Eochadha were lords in the County Down and south Antrim area for many centuries. ...

"By the time of the Norman Invasion in the late 12th century the Mac Duinnshléibhe (MacDonlevy) sept, named for their late 11th century ancestor Donn Slébhe Ua h-Eochadha, were chiefs of Uladh. The end of many centuries of Ulidian power, although dramatically reduced in the 4th and 5th centuries, came with the defeat of the MacDonlevys by John de Courcy in 1177.

"The Magennis (MacGuinness) sept, lords of Iveagh, are stated to be descended from the Dal Araidhe. Their lineage cites ancestry from Saran, a 5th century chief of Dal Araidhe during the time of St. Patrick, and continues through the line of the Eathach Cobha of the Iveagh area of County Down.

"Other septs included on the list of Ulster Kings included a MacMahon (MacMathghamhna) sept, lords of Oriel; a Lawlor (O Leathlobhair) sept; and an Ua Flaithrí sept."

See the discussion under the heading Conquest and Division of Ulster in my web pages Kings of Ulster and Kings of Ulidia. See also The Tribes of Uladh.

In Place-Names of Northern Ireland, Volume Three, County Down III, The Mournes, in the introduction at page xx, this information is provided on the territory of the Ui Eathach Coba:

"The County boundaries [of Down] were not settled all at once. Jobson's set of Ulster maps (c. 1590) and Norden's map of Ireland (1610) show the names and bounds of the three counties of Antrim, Down and Armagh. Both cartographers still include in Down the Cooley peninsula (now in Co. Louth) and also Loughgilly, O'Hanlon's chief seat in the barony of Orior (Co. Armagh). According to Jobson, Armagh extended across the outflow of the Bann into Lough Neagh to include Clanbrasil (later the barony of Oneilland East), and Down included Killultagh on the east bank of Lough Neagh (later the barony of Upper Massareene in Co. Antrim). A document in the state papers of 1603 refers to 'Down County alias Leycaile' (which includes Cowley and Omethe in modern Co. Louth), but gives Kilulto as a separate 'country' ... In 1605, Killultagh was annexed to Co. Antrim ... In the same year an inquisition on Clandeboy stated that the most noted boundary between the parts of it called Killultagh and Upper Clandeboy (later Castlereagh) was the river Lagan ... , and the Lagan remains the boundary between Cos Antrim and Down to this day.

"The land east of the Upper Bann on the shore of Lough Neagh, known as Clanbrasil, was traditionally Ui Eachach Coba or Magennis territory. In 1605 Clanbrassilagh 'which before lay doubtful between it and the County of Down' was formally annexed to the new County of Ardmaghe ... becoming eventually the barony of Oneilland East. .. . Modern Co. Down has retained one townland still called Kilmore, a strip of land connecting it with Lough Neagh, although Kilmore is part of the civil parish of Shankill, all the rest of which is in Co. Armagh. The artificiality of the County boundary in this area continued to cause problems: Sir William Petty in his baron and county maps ... thought that the Bann formed the northern boundary between Cos Down and Armagh and placed the Armagh parishes of Seagoe and Shankill to the west of the river instead of to the east. The diocese of Dromore, however, reflects the earlier boundary between Ui Echach Coba and Airgialla, in that it includes Seagoe and Shankill and follows the river Bann all the way to Lough Neagh ... "

At page 67 of the same book, under the heading The Barony of Iveagh, this additional information is given:

"The name Iveagh derives from Uib Echach (later spelled Uibh Eachach), the dative or locative form of the tribal name Ui Echach 'grandsons/descendants of Echu'. Ui Echach were one of the tribes of the confederation of the Ulaid 'Ulstermen', after whom the province of Ulster is named ... They shared the kingship of east Ulster with Dal Fiatach, the historic Ulaid, and with Dal nAraide of south Antrim who, like them, belonged to the ethnic group called Cruthin. The Echu from whom they claimed descent is reputed to have been either father or son of Crund Ba Drui, a descendant of Fiacha Araide, ancestor of Dal nAraide ... The Ui Echach were also known as the Ui Echach Coba to distinguish them from similarly named tribes, to the east in the Ards peninsula (Ui Eachach Arda), and to the west in Airgialla. The epithet was taken from the area they inhabited, known in early Irish as Mag Coba and appearing in Anglo-Norman documents as the castle of Moyvcove . . . It is also attested as part of the original name of the Iveagh parish of Donaghmore: Domnach Mor Maige Coba.

"As with other early tribes Ui Echach subdivided into various septs. The dominant group in medieval times were the Magennises, from Mac Oengusa 'son of Angus'. The Ui Echach genealogies ... list an Oengus, son of Aitid mac Laigne, who, according to the annals, was king of Ulster when killed in AD 898 ... , and Oengus mac Aitid is given by Keating as the ancestor of the family ... Their chief seat was at Rathfriland, near the hill of Knock Iveagh which provides a view of the whole barony. The 16th-century cartographer, Richard Bartless, who was interested in the inauguration sites of Irish chieftains, wrote beside Knock Iveagh on one of his maps: 'Lisenree where the Magennis is made' ... It seems likely that Lisenree derives from an original Irish Lios na Ri 'fort of the kings', but of the two modern places called Lisnaree in or near the barony, the closer is in the Lordship of Newry several miles further south, while the other is near Banbridge. As well as being tribal rulers, and patrons of Gaelic poets, many Magennises also became important churchmen, either in the local diocese of Dromore or further afield. ...

"The area covered by the diocese of Dromore is similar to but larger than the barony of Iveagh, and reflects the extent of earlier Ui Echach Coba influence to the south and north. The north-western boundary of the diocese follows the River Bann from Knock Bridge (on the modern boundary with Co. Armagh) all the way to Lough Neagh, and includes the district of Clanbrasil, now the barony of Oneilland East. Clanbrasil was traditionally part of Ui Echach but was annexed to the new County of Armagh in 1605. At the south-eastern corner of Lough Neagh, on the southern edge of Killultagh, was a district called Kilmore. This territory was lost to the Magennises in 1612 and, with the exception of the townland of Kilmore ... , is no longer in Iveagh. It remains, however, in the diocese of Dromore. North of Kilmore is the parish of Aghalee which is also in the diocese. It was part of Iveagh in 1584 but was annexed in 1605, with the rest of Killultagh, to Co. Antrim (barony of upper Massarene). In the south, Mourne was disputed between the dioceses of Down and Dromore throughout much of the medieval period, while Newry was included in Dromore until the 16th century. By the 18th century, however, the Lordship of Newry and the barony of Mourne had come to be regarded as forming an 'exempt jurisdiction' as far as the established church was concerned ... In 1869, both were restored to the Anglican diocese of Dromore, although in the Roman Catholic administrative system Mourne is now in the diocese of Down."


Explanation of the Table

The numbers in the left column are from the pedigree of Mac Aonghusa (Magennis, MacGuiness) in The Keating Genealogies. Keating's numbers proceed from father to son. Although many persons in this pedigree were not "kings," I assume they were all of the "nobility" of Ui Eathach Cobha, and include them in the table.

In column three, I show references to both the Annals of the Four Masters and the Annals of Ulster. As has been my usual practice in preparing these tables, I give first priority to the spellings and years in the electronic edition of the Annals of the Four Masters, even though the years in the Annals Ulster during this period are probably more accurate.

In the fourth column, I give various spellings of the name I have encountered on the next—partly to assist in the use of search engines. If there is a reference number designated SS# after a name, the reference is to the Stevens/Southworth/Medieval Database on World Connect. (Use Advance Search and enter the name only as a given name.)

Names in bold type in the second column are also listed as Kings of Ulidia. For additional explanation, see my web page Kings of Ulster—to Colla da Chrioch and Kings of Ulidia.

Other Ui Eatachs

Other Ui-Eathachs, not to be confused with the Ui Eathach Cobha, are:

Ui Eachach of Airthir (of Airghialla), one the tribes of the loose federation known as the Airghialla, located in the district of Tuaghy in the barony of Armagh, to the south and west of what is now the City of Armagh. These Ui Eathach are thought to be descended from Colla da Chrioch. See my web pages: Airghialla, and Colla da Chrioch, First King of Oriel.

Ui Eathach Arda: M551.3 Feargna, son of Aenghus, King of Ulidia, was slain in the battle of Druim Cleithe, by Deman, son of Caireall, and by the Ui Eathach Arda. U703.1 The battle of Mag Cuilinn in Ard Ua nEchdach between the Ulaid and the Britons, in which Radgann's son, an enemy of God's churches, fell. The Ulaid were victors.

Ui Eathach Mumham: M1063.6 Cathal, son of Donnchadh, lord of Ui-Eathach-Mumhan, i.e. lord of Raithlinn, was killed by his own son, i.e. the Finnshuileach. U1063.3 Cathal ua Donnchada, over-king of Uí Echach of Mumu ... [was] killed. M1088.9 A great slaughter was made of the foreigners of Ath-cliath, Loch-Garman, and Port-Lairge, by the Ui-Eathach-Mumhan, on the day that they jointly attempted to plunder Corcach-Mumhan. U1088.4 A great slaughter was inflicted on the foreigners of Áth Cliath and Loch Carman and Port Láirge by the Uí Echach of Mumu on the day they intended to plunder Corcach.

Ui Eathach Droma Lighean: Eochaidh, a quo Ui-Eathach Droma-Lighean, is supposed to have descended from Domhnall [Domhnall, Dabhaill], King of Aileach, a younger brother of Nial Glundubh, Irish Kings #170, who ruled from 915 to 917. Eochaidh and Domhnall were sons of Aedh Finnliath, Irish Kings #169, who ruled from 861 to 876, and from whom descended the McLaughlins. From this Eochaidh descended the O'Donnellys: Eochaidh, a quo Ui-Eathach Droma-Lighean | Ceallach | Seschnasach | Donnghal, a quo O'Donnelly | Dobhailen | Ceallachan O'Donnelly | Donnghal O'Donnelly | Echtighern O'Donnelly | Gilla-Macliag O'Donnelly, chief of Fear Droma, slain at Down by Sir John De Courcy, A.D. 1177. From the pedigree for the O'Donnellys in the Appendix to O'Donovan's edition of the Annals of the Four Master. Notes on the Pedigree of the McLaughlins of Tirconnell.

Tochar Eatach: M894.7 Donnagan, son of Fogartach, Tanist of Tochar Eathach, died.
