A Literary History of Ireland, from Earliest Times to the Present Day. Douglas Hyde

of Cork. The fifteenth was Muireadach, who was the first of the line to assume the surname of Mac Carthy, which he did from his father Carthach, from whom all the Síol Carthaigh [Sheeol Caurhy], or Seed of Carthach, including the Mac Fineens, Mac Auliffes, etc., are descended. The seventeenth was Saerbhrethach, from whose brother Murrough spring the sept of the O'Callaghans. The nineteenth was Callaghan of Cashel, king of Munster, celebrated in Irish romance for his warfare with the Danes. The twenty-third was Snedgus, who had a brother named Fogartach, from whose son Finguini sprang the Muinntir Finguini, or Finguini's People. The twenty-eighth was Falbi Flann, who was king of Munster from 622 to 633, from whose brother Finghin sprang the sept of the O'Sullivans. The thirty-second was Angus, from one son of whom Eochaidh [Yohy] Finn are descended the O'Keefes; while from another son Enna, spring the O'Dalys of Munster—he was the first king of Munster who became a Christian, and he was slain in 484. The thirty-fourth was Arc, king of Munster, from whose son Cas, spring the following septs: The O'Donoghue Mór—from whom branched off the O'Donoghue of the Glen—O'Mahony Finn and O'Mahony Roe, i.e., the White and Red O'Mahonys, and O'Mahony of Ui Floinn Laei, and O'Mahony of Carbery, also O'Mullane[6] and O'Cronin; while from his other son, "Cairbré the Pict," sprang the O'Moriarties, and from Cairbré's grandson came the O'Garvans. The thirty-sixth ancestor was Olild Flann Beg, king of Munster, who had a son from whom are descended the sept of O'Donovan, and the O'Coiléains, or Collinses. And a grandson from whom spring the O'Meehans, O'Hehirs, and the Mac Davids of Thomond. The thirty-seventh, Fiachaidh, was well known in Irish romance; the thirty-eighth was Eoghan, or Owen Mór, from whom all the septs of the Eoghanachts, or Eugenians of Munster come, who embrace every family and sept hitherto mentioned, and many more. They are carefully to be distinguished from the Dalcassians, who are descended from Owen's second son Cas. It was the Dalcassians who, with Brian Boru at their head, preserved Ireland from the Danes and won Clontarf. For many centuries the history of Munster is largely composed of the struggles between these two septs for the kingship. The thirty-ninth is the celebrated Oilioll [Ulyul] Olum, king of Munster, whose wail of grief over his son Owen is a stock piece in Irish MSS. He is a son of the great Owen, better known as Mogh Nuadhat, or Owen the Splendid, who wrested half the kingdom from Conn of the Hundred Battles, so that to this very day Connacht and Ulster together are called in Irish Conn's Half, and Munster and Leinster Owen's Half. The forty-third ancestor is Dergthini, who is known in Irish history as one of the three heirs of the royal houses in Ireland, whom I have mentioned before as having been saved from massacre when the Free Clans or Nobility were cut to pieces by the Unfree or Rent-paying tribes at Moy Cro—an event which is nearly contemporaneous with the birth of Christ. Hitherto there have been nine kings of Munster in this line, but not a single king of Ireland, but the forty-ninth ancestor, Duach Dalta Degadh, also called Duach Donn, attains this high honour, and takes his place among the Reges Hiberniæ about 172 years before Christ, according to the "Four Masters." After this a rather bald catalogue of thirty-six more ancestors are reckoned, no fewer than twenty-four being counted among the kings of Ireland, and at last, at the eighty-sixth ancestor from the Earl of Clancarthy, the genealogy finds its long-delayed goal in Eber, son of Milesius.

      It will be seen from this typical pedigree of the Mac Carthys—any other great family would have answered our purpose just as well—how families spring from clans and clans from septs—to use an English word—and septs from a common stem; and how the nearness or remoteness of some common ancestor bound a number of clans in nearer or remoter alliance to one another. Thus all septs of the great Eberian stem had some slight and faint tie of common ancestry connecting them, which comes out most strongly in their jealousy of the Eremonian or northern stem, but was not sufficient to produce a political alliance amongst themselves. Of a much stronger nature was the tie which bound those families descended from Eoghan Mór, the thirty-eighth ancestor from the first earl. These went under the name of the Eoghanachts, and held fairly together, always opposing the Dalcassians, descended from Cas. But when it came to the adoption of a surname, as it did in the eleventh century, those who descended from the ancestor who gave them their name, were bound to one another by the common ties or a nearer kinship and a common surname.

It will be seen at a glance from the above pedigree, how, taking the Mac Carthys as a stem, and starting from the first earl, the Mac Finneens join that stem at the eleventh ancestor from the earl, the Mac Auliffes at the fifteenth, the O'Callaghans at the eighteenth, the O'Sullivans at the twenty-ninth, the O'Keefes at the thirty-second, the O'Dalys[7] of Munster at the thirty-second, the O'Donoghues, O'Mahonys, O'Mullanes, O'Cronins, O'Garvans, and Moriartys at the thirty-fourth, the O'Donovans, Collinses, O'Meehans, O'Hehirs, and Mac Davids at the thirty-sixth.

      Now each of these had his own genealogy equally carefully kept by his own ancestral bardic historian. If, for instance, the Mac Carthys could boast of nine kings of Munster amongst them, the O'Keefes could boast of ten; and an O'Keefe reckoning from Donal Óg, who was slain at the battle of Aughrim, would say that the Mac Carthys joined his line at the thirty-sixth ancestor from Donal.

All the Gaels of Ireland of the free tribes trace back their ancestry, as we have seen, to one or other of the four great stocks of Erimon, Eber, Ir, and Ith. Of these the EREMONIANS were by far the greatest, the EBERIANS coming next. The O'Neills, O'Donnells, O'Conors, O'Cavanaghs, and almost all the leading families of the north, the west, and the east were Erimonian; the O'Briens, Mac Carthys, and most of the leading tribes of the south were Eberians.[8] It was nearly always a member of one or the other of these two stems who held the high-kingship of Ireland, but so much more powerful were the Eremonians within historical times, that the Southern Eberians, although well able to maintain themselves in the south, yet found themselves absolutely unable to place more than one or two[9] high-kings upon the throne of All-Ireland, from the coming of Patrick, until the great Brian Boru once more broke the spell and wrested the monarchy from the Erimonians. The Irians gave few kings to Ireland, and the Ithians still less—only three or four, and these in very early, perhaps mythic, times.

      If now we trace the O'Neill pedigree back as we did that of the Mac Carthys, we find the great Shane O'Neill who fought Elizabeth, traced back step by step to the perfectly historical character Niall of the Nine Hostages, son of Eochaidh Muigh-mheadhoin [Mwee-va-on], who was grandson of Fiachaidh Sreabhtine [Sravtinna], son of Cairbré of the Liffey, son of the great Cormac Mac Art, and grandson or Conn of the Hundred Battles, all of whom are celebrated in history and endless romance; and thence through a list containing in all forty-four High-kings of Ireland back to EREMON, son of Milesius, brother of that Eber from whom the Mac Carthys spring, and from whom he is the eighty-eighth in descent. The O'Donnells join his line at the thirty-sixth ancestor, the O'Gallaghers at the thirty-second, the O'Conor Don and O'Conor Roe and the O'Flaherty at the thirty-seventh. We find too, on examining these pedigrees, the most curious inter-mixtures and crossing of families. Thus, for instance, the two families of O'Crowley in Munster spring from the Mac Dermot Roe of Connacht, who, with the Mac Donogh, sprang from Mac Dermot of Moylurg in Roscommon, ancestor of the prince of Coolavin; while the O'Gara, former lord of Coolavin in the same county, to whom the "Four Masters" dedicated their annals, was of southern Eberian stock.

The great warriors of the Red Branch, the men of the original kingdom of Uladh [Ulla, i.e., Ulster], were of the third great stock, the IRIANS or race of Ir,[10] but they are perhaps better known as the Clanna Rudhraighe [Rury] or Rudricians, so named from Rudhraighe, a great monarch of Ireland who lived nearly three hundred years before Christ, or as Ulidians because they represented the ancient province of Uladh. But the Three Collas, grandsons of Cairbré of the Liffey, who was himself great-grandson of Conn of the Hundred Battles, and of course of the Eremonian stock, overthrew the Irians in the year 332, and burned their capital, Emania. The Irians were thus driven out by the Eremonians, and forced back into the present counties of Down and Antrim, where they continued to maintain their independence. So bitterly, however, did they resent the treatment they had received at the hands of the Eremonians, and so deeply did the burning of Emania continue to
