The Five O’Connor Crests of Ireland

O'Connor Crests

History of the O’Connor Name From Different Sources:


“O’Connor, with its variants Connor, Conner, Connors etc., comes from the Irish Conchobhair, from the personal name Conchobhar, perhaps meaning ‘lover of hounds’ or ‘wolf-lover’. This was one of the most favoured of early Irish names, and gave rise to the surname in at least five distinct areas, in Connacht (O’Conor Don), in Offaly (O’Conor Faly), in north Clare (O’Conor of Corcomroe), in Keenaght in Co Derry, and in Kerry (O’Connor Kerry). The Offaly family take their name from Conchobhar (d.979), who claimed descent from Cathaoir Mor, a second-century king of Ireland. They remained powerful in their original homeland until the sixteenth century, when they were dispossessed of their lands. The O’Connor Kerry were chiefs of a large territory in north Kerry, displaced further northwards by the Norman invasion to the Limerick borders, where they retained much of their power down to the seventeenth century. Today, the descendants of these O’Connors are far and away the most numerous, with the majority of all the many O’Connors in Ireland concentrated in the Kerry/Limerick/Cork area. However, the most famous of all the O’Connor families is that which arose in Connacht. The ancestor from whom they take surname was Conchobhar, King of Connacht (d.971), and direct ancestor of the last two High Kings of Ireland, Turlough O’Connor and Roderick O’Connor, who ruled through the twelfth century. Unlike the vast majority of the rest of the old Gaelic aristocracy, the O’Conors of Connacht managed to retain a large measure of their property and influence through all the calamities from the seventeenth century on. The line of descent from the last Chief of the Name is also intact; the current ‘O Conor Don’, recognized as such by the Chief Herald of Ireland, is Denis O Conor. The family seat remains in the ancestral homeland, in Castlerea, Co Roscommon.” Thanks to : Eolas na hEireann

Clan O’Connor

“Our name, in Irish Gaelic, is Ó Conchubhair. Today this is pronounced owe-kru-who-ear. In other pronounciations it ranges
from owe-con-ear to owe-con-coo-ear.

The spelling of the surname varies from sept to sept – mine, above, is O’Connor Kerry – and there are regional adaptions and other approximations such as Conaire (Conroy).

The name first appears in the literature at around the start of the Christian era, with the Ard-Rí (High King) Connor MacNessa. The name Conn had been popular, but unremarkable, since the Celtic incursion into Ireland brought new nomenclature to swell and develop the existing Formorian and Milesian names. There was another king at the time, Conaire Mór, who could be considered another early variant of Connor. But it appears that Connor represented something unique, powerful and remarkable.

Connor MacNassa was one of the most highly acclaimed rulers of Ireland – we would say today that he had great karma, he was a leader of great charisma, as was John F Kennedy, Abe Lincoln, Julius Caesar and some other publicly popular, very powerful and successful rulers. His public appeal was enormous. He reigned during the time of the Táin Bó Cuailgne (the quest for Cooley’s Bull) – the great saga of Cuchullain and Queen Maedb – which were heroic days indeed. He was a patron of the arts and of learning of all kinds. He opened the professions to all comers, which had previously been jealously guarded hereditary monopolies, with all of the concomitant inefficiencies and abuses.

His press was not entirely one-sided and good, however – he played the typical king’s part in the story of Deirdre and the Son of Usnach, betraying Naoisi and his brothers and driving Deirdre to her death, as recounted in the famous story that is one of the Three Sorrows of Storytelling.

Connor was married to the Amazonian Maedb, the warrior-queen of Connaught, but had to separate – I suppose that even a great and wonderful king wants to be able to put his feet up at the end of a long day and enjoy a quiet pipe without the missus jabbing a spear in his throne-seat and telling him in no uncertain terms just what she wanted conquered, and not taking any lip from himself about doing it tomorrow. Connor then married her sister Ethne, and whether he was happy with her or not we have no indication, but the change of pace seems to have appealed to him and they lived together for many a day.

Now that word `conquered’ appeared above, and it has a possible connection with this story. Julius Caesar some fifty-five years BC had first invaded England, having already brought Gaul into the Empire and contained the Germans and the Belgae. His title was Imperator – the commander – but the name he had given himself – Caesar – was how he was referred to by both Romans, provincials, enemies and foreigners. Later emperors took the name Caesar because it said, simply, eloquently and unmistakably `The Commander of the Roman World.’ A millenium and a half later, the kings of Russia adapted the same title as `Tsar’, the Germans as `Kaiser’.

And in the Celtic world, Connor became the title of the one who triumphed, of he who won rule of the land. Perhaps it derived for Conn – but that’s not important. Even today, the inherent meaning of Connor is `the wilful one.’ But one thousand years later, in a once-Celtic land which had been occupied by Romans for a few centuries, and into which had streamed Danes and Norse and Angles and Saxons – as well as Irish and Scots – a foreign invader defeated local forces and established his rule on this land. Is it so acceptable to the Brits to believe that the name given to William by the locals – Conqueror – derived from the Irish / Celtic Connor (pronounced con-coo-ear) rather from the postulated ‘conquirre’ of Latin, a term apparently cobbled together in medaevial times and interpreted today as `questing together’?”

O’Connor or O’Conor

“O’Connor or O’Conor is perhaps the most illustrious of all Irish surnames, though this view would, no doubt, be disputed by the O’Neills, the O’Briens, the O’Donnells and one or two other great and famous septs. It is borne by six distinct septs located in different parts of the country of whom four survive in considerable numbers. The most important are the O’Connors of Connacht – the main branches of this sept being O’Conor Don, O’Conor Roe and O’Conor Sligo. these are descended from Conchobhar, King of Connacht (d. 970), and the last two High-Kings of Ireland were of this line, viz., Turlough O’Connor (1088-1156) and Roderick O’Connor (1116-1198), both of whom were progressive monarchs. Their direct descendant, as certified by the Genealogical Office, Dublin Castle, is the present O’Conor Don: Denis O’Conor, and it is interesting to note that this important and aristocratic family consistently maintained its position not withstanding the fact that they remained inflexibly Catholic. Evidence of this is abundant in all the sixteenth, seventeenth and eighteenth century manuscripts.

In dealing with the landed proprietors of Connacht, among the most distinguished members of the O’Conor Don stock four O’Conors of Belnagare are outstanding in the field of culture: Charles O’Conor (1710-1791), antiquary and collector of Irish manuscripts; his two grandsons, Rev. Charles O’Conor, D.D., P.P. (1764-1828), librarian at Stowe and author, inter alia, of Rerum Hibernicarum Scriptores Veteres, and Matthew O’Conor (1773-1884), author of History of the Irish Catholics etc; and Charles Owen O’Conor, O’Conor Don (1838-1906), President of the Royal Irish Academy and of the Society of Preserving the Irish Language and author of The O’Conors of Connacht. In the military sphere Cabrach O’Conor (1584-1655) and Hugh O’Conor (d.1669), respectively son and grandson of O’Conor Don, took a prominent part in the 1641-1652 wars. Three of this sept were outstanding in the Irish Brigade. More recently, one of the Roe branch, General Sir Luke O’Connor (1832-1915), who had enlisted as a private soldier in the British army, won the V.C. and a commission for his remarkable bravery at the battle of Alma.

O’Connor Kerry, as the chief of the Munster O’Connors was called, derives his name from a different Conchobhar. He was lord of an extensive area in north Kerry, but after the invasion of 1170 Anglo-Norman pressure pushed the O’Connors northwards towards the Shannon estuary. However, they still retained a considerable territory, in fact the greater part of the modern barony of Iraghticonor, which is an attempt at a phonetic spelling of Oireacht ui Chonchobhair, i.e. O’Connor’s district of government: their chief stronghold in Iraghticonor was Carrigafoyle Castle. From this sept came a number of distinguished officers of the Irish Brigade in France, the best known of whom was Arthur O’Connor (1763-1852), United Irishman and later a general in Napoleons army; his brother Roger O’Connor (1761-1834), an erratic character who was also a member of the United Irishmen, and the latter’s son, Fergus O’Connor (1794-1855), the Chartist.

Some of this family changed their name to Conner. The three most notable Irish-American O’Connors were of this sept: the brothers Michael O’Connor (1810-1872), and James O’Connor (1823-1890), both Catholic bishops in U.S.A., and Patrick Edward O’Connor (1820-1871), pioneer, Indian fighter and soldier in the Civil War on the Confederate side. The O’Connor sept of Kerry is at the present day much the most numerous of them all. It is estimated that there are almost 30,000 persons of the name in Ireland to-day – it comes ninth in the list of commonest surnames and the vast majority of these are from Kerry or from the adjoining counties of Cork and Limerick.

The O’Connors of Corcomroe, a barony in north Clare on the shores of the Atlantic, are still extant. The eponymous ancestor in this case was Conchobhar, lord of Corcomroe (d. 1002).

The fourth of the surviving septs was O’Connor of Offaly. O’Connor Faly, as the chief was called, was of royal descent, his ancestor being Cathaoir Mor, King of Ireland in the second century. The eponymous Conchobhar in this case was much later than Cathaoir and belongs to historical times as he died in 979. This sept was constantly engaged in war with the invader until the middle of the sixteenth century when they were vanquished and dispossessed of most of their estates. They were still in Offaly in 1689, as Col. John O’Connor was member for Philipstown in King James II’s Parliament and they were represented by the family of O’Connor-Morris of the same county until quite recently.

It should be added that there was also a powerful sept of O’Connor in Keenaght (Derry), which in the twelfth century was overpowered by the O’Kanes. They are mentioned here because, though as a sept they were eliminated, families of O’Connor are still found in that part of Ulster and it may be assumed that they are descended from the once famous O’Connors of Glengiven who were of royal blood, their ancestor being Cian, son of Oilioll Olum, King of Munster in the third century.

The history of the O’Connors, particularly, those of Connacht, forms the subject of a number of books which can be consulted for detailed information concerning these important septs.”

Excerpt: “Irish Families Thir Names, Arms and Origins ” by Edward Maclysaght


There are six distinct septs of the name. The first are the OConnors of Connacht-the main branches being OConor Don, OConor Roe and OConor Sligo. They are descended from Conchobhar, King of Connacht(d.970) and claim the last two Kings of Ireland, Turlough OConnor(1088-1156) and Roderick OConnor(1116-1198). Their direct descendant is the present OConnor Don: Denis OConnor. It should be noted that this important family consistently maintained its position AND remained inflexibly Catholic.

The O’Connor Kerry derive their name from a different Conchobhar who was Lord of an extensive area of Northern Kerry, but after the Anglo-Norman invasion of 1170, they were pushed northward toward Shannon. The OConnor Kerry sept is the most numerous sept. Estimates put the number of this sept in Ireland today at 30, 000. Some members of this sept changed their name to Conner. The OConnors of Corcomroe, a barony in North Clare, are descended from Conchbhar, lord of Corcomroe(d. 1002) The OConnors of Offlay are descended from OConnor Faly, who in turn was descended of Cathaoir Mor, King of Ireland in the second century.

The OConnor in Keenaght (Derry) were once very powerful. In the twelfth century they were overpowered by the O’Kanes. Families of these OConnors are still found in that part of Ulster. The OConnors of Glengiven were of royal blood, their ancestor being Cian, son of Oilioll Olum, King of Munster in the third century. Thanks to: Completly Irish

Ballinrobe, County Mayo History (refers to O’Connors)

Ballinrobe is one of the oldest towns in County Mayo. Established as a borough in the wake of the Norman conquest of the thirteenth century, this beautiful and historical town is bordered by Cong to the South, Lough Mask to the West, and Lough Carra and Moore Hall to the North.

A recent archaeological survey of Ballinrobe and district identified a wealth of sites and monuments dating back to the neolithic and early bronze age, including crannogs, ringforts, souterains, fulachta fiadh, standing stones, and a variety of burial sites such as cysts, barrows, hedges, and two very impressive cairns associated with the Battle of Moytura.

Evidence of early Christian and medival times can be seen in the remains of the various churches and town houses in the locality. Of particular significance is the 14th century Augustinian Priory of Ballinrobe. The O’Connors were responsible for the building of many fine churches in this part of County Mayo – Ballintubber, Cong, Shrule, and the Holy Rood church in Ballinrobe. This latter Church was erected on the site of a 7th century church built by a Chieftain named O’Ruadhain who lived in Liskillen. Thanks to:

O'Connor Septs

Septs: The Clans eventually broke up into a number of distinct septs or groups. These groups were headed by an original member of the clan and dominated a particular part of the countryside. It was not uncommon for septs from the same clan to be found in completely different parts of the country (O’Connor for example) so it is important when researching your roots to try to find out the original part of the country that your ancestors came from as this may be a completely different area from that where the ‘major’ sept was domicile. The sept system was an integral part of Gaelic society and survived and was even propagated by the Norman invaders. The system did not survive the English invasion and colonisation of the seventeenth century however, and it became a disadvantage to have a Gaelic sounding name.

Anglicization: The Penal laws that were enforced by the colonists attempted to completely subjugate the Gaelic way of life. It is about this time then, that many Gaelic names changed to their Anglo equivalent or translation. This can cause confusion as many of the names were misinterpreted or misspelled. (O’Connor, Connor, Conner, Conaire). There are many different origins for Irish names today but the vast majority can be broken down into either of three categories: Gaelic Irish, Cambro-Norman, and finally Anglo-Irish.

O’Conor Don  ~  Heraldic History

Sir Bernard Burke, Ulster King of Arms, didn’t mince words in the 1912 edition of A Genealogical and Heraldic History of the Landed Gentry of Ireland, when he prefaced the pedigree of the then O’Conor Don in the following terms:

“No family in Ireland claims greater antiquity and no family in Europe, royal or noble, can trace its descent through so many generations of legitimate ancestors.”

Death of O’Conor Don

Denis O’Conor Don, President of the Genealogical Society of Ireland, who died on 10 July aged 88 years, belonged to one of the oldest families in Europe. The O’Conors descend from the kings of Connacht and high kings of Ireland. For that reason, the had of the family is regarded as the senior hereditary chieftain of Ireland and has been styled the ‘O’Conor don’ since the fourteenth century. According to the obituary published in the Irish Times on Saturday 22 July ‘it is generally acknowledged that the holder of the title would be the foremost claimant to the Irish throne, if one were porposed. over the last few hundred years, members of the O’Conor family have continued to contribute to the social, political, cultural and religious life of Ireland. The fact that they remained staunchly Catholic during the dark days of the Penal Laws in the eighteenth century , is a source of great pride.’ Born in London in 1912, the son of Chalres William O’Conor and Evelyn Lowry-Cowrry, Denis inherited his tittle in 1981 form his cousin Fr. Charles O’Conor, a Jesuit priest. Since inherititng the O’Conor Don title, Denis used his position to promote an interest in our national heritage from genealogy, local history to archaeology. He became President of the Dun Laoghaire Genealogical Society in 1991 and President of the Genealogical Society of Ireland in 1999. Members remember with sincere fondness the tales of his long and distinguished carrer and life, with which he regaled us over a pint or two following the Society’s open meetings which he loved so much. He is survived by his wife Rosemay (nee O’Connell Hewett) and three sons. Desmond, Kieran and Rory. A young daughter, Gail, died at the age of thirteen years. Desmond, Denis’s eldest son by his first wife Elizabeth Marris, inherits the ancient Irish Gaelic title of O Conchubhair Donn [From the Genie Gazette]

information from Waterlilys about our name!

Dear O’Connor researchers,

I just found out something about our name that I wanted to share with you. Ready to be surprised? There are numerous misusages of Gaelic to English, the most pervasive of which is the apostrophe in the family names such as O’Connor ! Get this:

The Irish noun Ó (with an accent above) means descendant….. It has been and is confused with the contraction of the preposition “of “, as in jack o’lantern. Bottom line is, our names never should have had an apostrophe!

I am sure some of you have come across our name spelled in gaelic, but for those who havent; heres how the name looks in Gaelic (at least in the west Dingle [Munster] version of Irish):

O’Connor = Ó Conchúir

(their story is our story)



Tara’s Harp


The harp that once through Tara’s Hall the soul of music shed
Now hangs as mute on Tara’s wall as if that soul were fled
So sleeps the pride of former days so glory’s thrill is o’er
And hearts that once beat high for praise now feel that pulse no more
No more to chiefs and ladies bright, the harp of Tara swells
The chord alone, that breaks at night, its tale of ruin tells
This freedom now so seldom wakes, the only throb she gives
Is when some heart indignant breaks, to show that still she lives

by Thomas Moore 1779-1852
