Even in the annals of Ireland it would be hard indeed to find a nobler record than that of the O'Byrnes of Wicklow. Through a long line of warriors and chieftains they were eminently distinguished for devotion to the sacred cause of Faith and Country. High-souled in their patriotism, fearless and fierce in defence of their Nation's rights, proud of their race, and intensely attached to the mountain crags and exquisitely picturesque glens of their ancient patrimony, they, during centuries of wrong, persecution, plunder and perfidy, held their ground invincibly, and fought against their ruthless oppressors, with courage indomitable and fortitude heroic. Their motto Certavi et Vici was truly appropriate. The love of freedom, "bequeathed from bleeding sire to son," burned so fiercely in their hearts, that it can scarcely be considered an exaggeration to say, they contended for four hundred years unconquered. It was almost as natural to them to fight as it was to breathe, and, in a sense, as necessary; because they were perpetually assailed, and every element of force and every base subterfuge, that flendish minds could conceive, were made available to ruin and annihilate them. By nature dauntless and combative, yet merciful and humane; and by the treachery of perfidious enemies obliged to be ever watchful, it may be believed, that they almost slept with their battle-axes grasped, at all times ready to spring at the foe, repel aggression, aid their kinsmen, and jealously guard their stronghold, wooded hills and crystal watered valleys of the beauteous region which they ruled and loved. Not only do they figure prominently in the pages of Irish history, but their deeds and exploits have furnished touching themes for song and story. No persecution, however malignant, could deter them, no allurement could seduce them. Threat and overture they spurned with equal contempt; and to their eternal honour it is stated, that there was never "a king's or a queen's O'Byrne," and that they were the very last of the Irish clans to yield to the Saxon. Some writers seem to think, that they did not always receive that prompt aid from other septs which their common cause demanded; but it is not our purpose to draw contrasts, and most assuredly it is not our desire to pass, perhaps, unmerited censure. All created beings have their faults and follies, and exemption from the sins and frailties of human nature cannot be claimed for the O'Byrnes; but it can be pleaded in extenuation of their errors, that their virtues were many and their sufferings great.

Numbers of the O'Byrnes, in different generations, consecrated themselves to the service of the Church, at the altar, and in the cloister; some of them founded abbeys and generously maintained them. Their Faith was as warm in them as the burning rays of the noonday sun, and as immovable as the base of "The Golden Spears" which tower high in their beloved Wicklow; and proudly it can be proclaimed, that the mother of the great Saint Laurence O'Toole was an O'Byrne. At the present day, the descendants of the O'Byrne clan are, perhaps, more numerous than those of any other. At all events, they appear to be more concentrated, and to cling more tenaciously to the historic county of their ancestors. The saying that: "You will find a Byrne in every bush in Wicklow," can be easily understood; but it is strange and sad to think, that few of them have retained the distinctive prefix O'. No clan has a more rigid right to it. One historian alludes to the name of the O'Byrnes as "heroic;" surely, those who bear it should be proud of it, and all the O'Byrnes - those who can trace their pedigree connectedly, and those who cannot, should keep before their vision the noble example of their martyred forefathers. The old spirit of clanship should bind them firmly together in love for kith and kin and country. The past glories of our land should urge them to labour incessantly for her future greatness. Thank God, she is not now as she was in generations gone by, still she is sadly placed in many respects, and her children are bound by ties the tenderest, and obligations the most sacred, to make every effort that the precepts of religion, the principles of justice, the dictates of honour, and the chastened sympathies of exalted minds can sanction for her elevation amidst the proudest nations of the earth. Ireland is a country of beauty, fruitfulness, and holiness. The O'Byrnes of the past loved her with all the intensity of their impassioned souls. In proof of their faithfulness to God and their country, they hesitated not to pour out their blood in crimson streams. The same sacrifices are not now required from their descendants, but the latter should be guided and governed by the characteristic instincts of their great race, which would infallibly teach them, that their first and highest aspiration should be to live and die for God and Ireland. [John O'Hart]

O'Byrne is in Irish Ó Broin i.e. descendant of Bran (earlier form Broen), King of Leinster, who died in 1052. With their "cousins", the O'Tooles the O'Byrnes were driven from their original territory in the modern Co. Kildare at the time of the Anglo-Norman invasion and settled in the wilder country of south Wicklow about the year 1200. There were two main branches of the O'Byrnes of which the senior soon sank into obscurity, but the junior line, which occupied the country between Rathdrum and Shillelagh, became a sept of great importance and, like their neighbours the O'Tooles in north Wicklow, were particularly noteworthy for their persistent and largely successful resistance to English aggression. They continued regularly to inaugurate chiefs of the sept up to the end of the sixteenth century. The seat of their chiefs was at Ballinacor and their territory was called Crioch Branach, the sept itself being known as Uí Broin or Branaigh. Many of these were renowned in the military history of Ireland, the most famousbeing Feagh or Fiacha MacHugh (or son of Aodh) O'Byrne (1544-1597) who, though he was prominent in rebellion and was killed in battle, is perhaps best remembered for his part in the escape of Hugh Roe O'Donnell from his prison in Dublin Castle in 1591. Feagh O'Byrne resided at Ballinacor, in Glenmalure; and was chief of that sept of the O'Byrnes called Gabhail Raighnaill. His father, Hugh, who died in 1579, was far more powerful than The O'Byrne, and possessed a large tract of territory in the county Wicklow. Upon the death of The O'Byrne, in 1580, Feagh MacHugh O'Byrne became the leader of his clan, and one of the most formidable of the Irish Chieftains. In 1580 he joined his forces to those of Lord Baltinglass, and defeated Lord Grey. After holding out in the rocky fastnesses of his principality for several years, he was, in 1595, driven up Glenmalure, and his residence at Ballinacor was occupied by an Anglo-Irish garrison. He then made terms, but seized the first opportunity of driving out the garrison, and razing the fort. He was killed in a skirmish with the forces of the Lord Deputy, in May, 1597, and his head was impaled on Dublin Castle. The family estates were confirmed to his son Felim (or Phelim), by patent of Queen Elizabeth, but he was ultimately deprived of them by the perjury and juggling of adventurers under James I.; and although in 1628 acquitted of all the charges brought against him, he was turned out upon the world a beggar. He is remembered in the old Irish rebel song "Follow me Up to Carlow" the chorus of which goes . . .

Curse and swear Lord Kildare Fiach will do what Fiach will dare.
Now Clanwilliam have a care. Fallen is your star low.
Up with halberd out with sword. On we'll go for by the Lord,
Fiach Mac Hugh has given the word - Follow me up to Carlow.

His son Phelim O'Byrne was the victim of one of the many unscrupulously trumped-up charges which disgraced English seventeenth century administration in Ireland: the Viceroy Falkland was in turn disgraced, but notwithstanding that the O'Byrnes lost the greater part of their estates in consequence of his action. The celebrated "Leabhar Branach" or "Book of the O'Byrnes" is a collection of Gaelic poetry by some thirty-five different authors, dealing for the most part with the exploits and personalities of the O'Byrnes in the sixteenth century: it was made about 1662.

In the next century O'Byrnes were prominent in the 1798 insurrection, notably the brothers Garret O'Byrne (1774-1830) and William Byrne (1775-1799), the latter of whom was hanged; and Miles Byrne (1780-1862), who subsequently distinguished himself in France and was awarded the Legion of Honour. Other O'Byrnes have been notable in France: one branch, which was admitted to the ranks of the French nobility in 1770, was a leading family of Bordeaux before the Revolution and Garret Byrne, mentioned above, was among the distinguished exiles to that country; while in America, Irish-born Most Rev. Dr. Andrew Byrne (1802-1862), first bishop of Little Rock, is remembered as a pioneering Catholic in Indian territory. In recent times one of the best known and most popular figures in the life of the Irish capital was Alderman Alfred Byrne (1882-1956), who was ten times Lord Mayor of Dublin.

The Byrnes, who in recent generations have increasingly resumed the discarded prefix O, are very numerous in Ireland today, the name being in the seventh place in the list of commonest names. The great majority of these were born in Dublin, where Byrne is the commonest found surname, in Co. Wicklow and adjacent counties.

Heraldry
The sept arms of O'Byrne are recorded by both the Office of the Chief Herald of Ireland and Burke's General Armory as
Arms: Gules a chevron between three dexter hands couped at the wrist Argent. Crest: A mermaid with comb and mirror proper. Motto: certavi et vici (I have fought and won).
The Byrnes of county Louth bore similar arms but added a mullet Azure, borne on the chevron, while in their crest the mermaid is charged with an escallop Gules.

Ancient Genealogy - according to O'Hart

37. Heremon: son of Milesius. He and his eldest brother Heber were, jointly, the first Milesian Monarchs of Ireland; they began to reign, A.M. 3,500, or, Before Christ, 1699. After Heber was slain, B.C. 1698, Heremon reigned singly for fourteen years; during which time a certain colony called by the Irish Cruithneaigh, in English "Cruthneans" or Picts, arrived in Ireland and requested Heremon to assign them a part of the country to settle in, which he refused; but, giving them as wives the widows of the Tuatha-de-Danans, slain in battle, he sent them with a strong party of his own forces to conquer the country then called "Alba," but now Scotland; conditionally, that they and their posterity should be tributary to the Monarchs of Ireland. Heremon died, B.C. 1683, and was succeeded by three of his four sons, named Muimne, Luigne, and Laighean, who reigned jointly for three years, and were slain by their Heberian successors.
38. Irial Faidh ("faidh": Irish, a prophet): his son; was the 10th Monarch of Ireland; died B.C. 1670. This was a very learned King; could foretell things to come; and caused much of the country to be cleared of the ancient forests. He likewise built seven royal palaces, viz., Rath Ciombaoith, Rath Coincheada, Rath Mothuig, Rath Buirioch, Rath Luachat, Rath Croicne, and Rath Boachoill. He won four remarkable battles over his enemies: - Ard Inmath, at Teabtha, where Stirne, the son of Dubh, son of Fomhar, was slain; the second battle was at Teanmhuighe, against the Fomhoraice, where Eichtghe, their leader, was slain; the third was the battle of Loch Muighe, where Lugrot, the son of Moghfeibhis, was slain; and the fourth was the battle of Cuill Martho, where the four sons of Heber were defeated. Irial died in the second year after this battle, having reigned 10 years, and was buried at Magh Muagh.
39. Eithrial: his son; was the 11th Monarch; reigned 20 years; and was slain by Conmaol, the son of Heber Fionn, at the battle of Soirrean, in Leinster, B.C. 1650.

40. Foll-Aich: his son; was kept out of the Monarchy by Conmaol, the slayer of his father, who usurped his place.
41. Tigernmas: his son; was the 13th Monarch, and reigned 77 years; according to Keating, he reigned but 50 years; he fought twenty-seven battles with the followers of the family of Heber Fionn, all which he gained. In his reign gold was mined near the Liffey, and skilfully worked by Inchadhan. This King also made a law that each grade of society should be known by the number of colours in its wearing apparel: - the clothes of a slave should be of one colour; those of a soldier of two; the dress of a commanding officer to be of three colours; a gentleman's dress, who kept a table for the free entertainment of strangers, to be of four colours; five colours to be allowed to the nobility (the chiefs); and the King, Queen, and Royal Family, as well as the Druids, historians, and other learned men to wear six colours.
This King died, B.C. 1543, on the Eve of 1st of November, with two-thirds of the people of Ireland, at Magh Sleaght (or Field of Adoration), in the county of Leitrim, as he was adoring the Sun-God, Crom Cruach (a quo Macroom).

Fiacha at length (B.C. 1448) fell in the battle of Bealgadain, by the hands of Eochaidh Mumho, the son of Moefeibhis, of the race of Heber Fionn.
45. Aongus Olmucach: his son; was the 20th Monarch; in his reign the Picts again refused to pay the tribute imposed on them 250 years before, by Heremon, but this Monarch went with a strong army into Alba and in thirty pitched battles overcame them and forced them to pay the required tribute.

In order to prevent these children encroaching on each other he divided the Kingdom into twenty-five portions, allotting to each his (or her) distinct inheritance. By means of this division the taxes of the country were collected during the succeeding 300 years. All the sons died without issue except two, viz: - Laeghaire Lorc, ancestor of all the Leinster Heremonians; and Cobthach Caolbhreagh, from whom the Heremonians of Leath Cuinn, viz., Meath, Ulster, and Conacht derive their pedigree.
Ugaine was at length, B.C. 593, slain by Badhbhchadh, who failed to secure the fruits of his murder - the Irish Throne, as he was executed by order of Laeghaire Lorc, the murdered Monarch's son, who became the 68th Monarch.
