First Generation



1. Carrtahch, King of Eoghanacht. Carrtahch, King of Eoghanacht died in 1045.


Carthach, was a king of Eóghanacht Chaisil who died in 1045 A.D.  (pronunciation: 'ch' in Gaelic is like the ch sound in Yiddish (Chanukah)  or German (nacht), very guttural and from the back of the throat.)   Carthach's son, Muiredach mac Carthach, was the first of his race to assume the name of "MacCarthaigh", which was anglicized to MacCarthy and  its variations later.

                        i.           Tadhg McCarthy, King of Desmond. Tadhg McCarthy, King of Desmond died in 1123. Tadgh I, 1118-1123.  He was the eldest son of Muiredach, King of Eóghanacht Chaisil, and the great-great-grandson of the last Eóghanacht King of Munster, Donogh II (obit. 963; Donogh was the son of King Ceallacháin of Munster who died in 954).  In 1123, seriously ill, Tadgh abdicated the throne in favour of his brother Cormac.  This was in accord with Brehon Law, which demanded the physical perfection of a king.


All of the information on the Kings of Desmond was taken from the article

                      iii.           Donogh. Donogh died  BET. 1143 - 1144.


Donogh III, King of Desmond, First Reign 1127.  Cormac II was succeeded, briefly, by his younger brother Donogh.  On the restoration of Cormac III, Donogh III was banished to Connacht.


Donogh III, Second Reign, 1138-1143.  Cormac was again succeeded as King of Desmond by his brother, Donogh.  He had been exiled into Connacht by Cormac III in 1127 but was received back into favour following the Treaty of Abhall Ceithearnaigh between Munster and Connacht in 1138.  Following the collapse of Desmond in 1139 he fled to the Décies establishing his principal seat at Lismore.  In 1142 he challenged the Dál gCais for the crown of a reunited Munster.  He became ill, and was taken captive by Toirdhealbhach, son of Diarmaid Ó'Briain.  He subsequently died in 1143-44.


Third Generation



3. Cormac McCarthy of Magh Theamhach. Cormac McCarthy of Magh Theamhach died in 1138.


Cormac II, King of Desmond First Reign 1123-1127.  He was the brother of Tadgh I.  In 1125 he besieged and captured Limerick, the capital of Dál gCais Thomond.  This was equated with the "taking of the Kingship of Limerick", and thus Cormac became King of Munster, which had been reunited by the fall of Limerick.  In 1127, Cormac was deposed by the nobles of Munster.


Cormac III, Second Reign, 1127-1138.  Within months of his deposition Cormac was restored to both the kingship of Desmond and Munster.  In 1138 Cormac III was murdered as the instigation of the O'Briens.  For that year MacCarthaigh's Book reports that:"Cormac, son of Muireadach MacCarthaigh, King of the two provinces of Munster (Desmond and Thomond),  and defender of all Leath Mogha, the most pious and valorous of men, the  best for bestowing food and clothes (on the poor), was, after building  the church of Cormac at Cashel and twelve churches at Lismore,  treacherously killed by Diarmaid Súgach son of Mathghamhain Ó'Conchobhair  Ciarraigh (O'Connor Kerry) and Ó'Tailcín, at the instigation of  Toirdhealbhach, son of Diarmaid Ó'Briain, in his own house at Magh  Tamhnach."

Sixth Generation



6. Domhnall God McCarthy Reagh of Carbery. Domhnall God McCarthy Reagh of Carbery died in 1252.


Donall II (Domnall Got Cairprech), King of Desmond,1247-1252.  Donal II was the son of Donal I, and the younger brother of Dermod II and Cormac IV.  Donal II succeeded to the throne of Desmond by tanistry.  In 1252 Donal II was murdered by "John son of Thomas Fitzgerald."  The MacCarthy Reaghs, Lords of Carbery, were descended from him.


CARBERY.  Mac Carthy Reagh was overlord of the of the O'Driscolls, O'Mahonys and O'Donovans as well as a number of Mac Carthy septs.  The latter had castles at Kilcoe, Cloghane, Castlederry, Ballinroher, Dunmanway, Togher, Ballineen etc. 2 Blessed Thaddeus Mac Carthy (1456-1492) is said to be one of the Mac Carthy Reagh.  He is still venerated at Ivrea (Italy) where he died.  Another Tadhg Mac Carthy, of the Enniskeane branch (Sliocht Diarmada), was Bishop of Cork, Cloyne and Ross, 1726-1747.  Finghin Mac Carthy Reagh (who died 1505) married a daughter of Thomas, Earl of Desmond.  The Book of Mac Carthy Riabhach' (or 'The Book of Lismore') was compiled for them.  Their son Donnell married a daughter of the most powerful Geraldine of all, Gear¢id M¢r, the Great Earl of Kildare.  Another Finghin (Florence) of Carbery, grandson of the last-mentioned Donall, was probably the best-known of all his clan.  He also contributed to the sources of the nation's history by carefully preserving some old Irish manuscripts, which came to be known as 'Mac Carthaigh's Book'.  However it was in the political field that he left his greatest mark.  He married secretly at Muckross, Eleanor, daughter and legitimate heiress of Donnell Mac Carthy M¢r, Earl of Clancarthy, and alliance which alarmed the English government, as it bound together several native and Old English families.  He spent forty years in London, half of them in the tower, and was buried at Saint Martin's-in-the-Field, near Trafalgar Square, nowadays renowned for its Musical Academy.  Even while confined to the city of London, 'this cunning hypocrital Traytor' was a constant thorn in the side of the English.  His brother, Dermot Maol, fought with Hugh O'Neill at Kinsale and shortly after his lands were confiscated.  He is buried in Timoleague Abbey.

Fingen V, King of Desmond,1252-1261.  Fingen V was the eldest son of  Donal II.  His right of succession was challenged by his first cousin, Domnall Ruad, eldest surviving son of Cormac IV.  Strictly speaking, according to the law of tanistry, Donal (Domnall Ruad) had a prior right to the succession.  Fearing the permanent exclusion of his branch of the royal family from the throne he joined forces with the Anglo-Normans and fought on their side at the Battle of Callan.  Fingen's army routed his opponents at Callan and seriously weakened the Anglo-Norman colony in Kerry and southwest Cork.  Fingen died in 1261.

DUHALLOW.  The general consensus amongst genealogists seems to be that the Duhallow Mac Carthys were descended from Diarmuid (Ruadh), son of Cormac Fionn Mac Carthy Mór 4.  Diarmuid's grandson was Donnchadh na Sgoile, whose grandson in turn was Donogh Mac Carthy.  This gentleman had a son, Donogh Og, who died 1501.  The latter was married twice, firstly to a daughter of the White Knight, by whome he had a son, Cormac; secondly, to a daughter of the Mac Carthy Mór, by whom he had another son, Eoghan (Owen).  It would seem that the additional distinctive surname traditionally applied to the Duhallow Mac Carthys derives from this gentleman also, i.e. the Mac Donogh Mac Carthys, whose chief residence was at Kanturk.  At any rate, between these two branches of Clan Carthy in Duhallow, there existed, according to the now accepted norm, an embittered family rivalry for the greater part of the sixteenth century, during which period three family murders took place.  Much of the internal tensions which were present in this century was generated by the Tudor policy, 'Surrender and Regrant', by which the English monarchs hoped to achieve a degree of legal uniformity, based on the feudal  principle of primogeniture.  The struggle between the embattled factions in Duhallow had everything to do with ultimat control of clan territory.


The Lords of Duhallow, under the acknowledged suzerainty of the Mac Carthy Mór, were themselves overlords of three other clans: the Mac Auliffes, the o'Callaghans and the O'Keeffe's, who paid certain dues.   Similar dues, which however did not amount to very much, had to be paid to the Mór out of Duhallow.  The paramount lord had, for example, demesne lands in the Boherbue area.  He was also entitled to four annual sorrens  (days of entertainment for himself and his retinue), which in Duhallow was compounded into an annual tax of £20-13-4, evenly assessed on the four clans.  He had as well the 'giving of the rod' at each chieftain's inauguration and, in time of war, the 'finding' of twenty-seven gallowglasses.


The struggle for the Lordship of Duhallow ended in favour of the junior branch of Donogh Og's family.  In 1614, Dermod Mac Owen, descendant of Eoghan Mac Donogh Mac Carthy, surrendered his Gaelic title and one year later was regranted a title in English law, by which succession to the honour was confined to his immediate family, thus discriminating against all other Mac Carthys in Duhallow.  Possession was short-lived, Dermod's successors becoming embroiled in the disastrous troubles of 1641-1652.   When Cromwell's work was done, the Mac Carthy estates were in the hands of Philip Percival, heir of Sir Philip Percival, to whom they had been heavily mortgaged.  These debts were unredeemed and the Percivals were allowed to foreclose.


Dermod Mac Owen, who claimed that his rival Cormac Mac Donogh of Curragh was descended from the elder but illegitimate offspring of their common ancestor, was one of four Gaelic chieftains who petitioned the Pope to excommunicate Queen Elizabeth I, was also an ally of Florence Mac Carthy and was consequently considered a traitor by the English establishment.   In 1598 he pressed his claim to the title of Mac Carthy Mór, which had become vacant, much to everbody's surprise and apparently on very weak grounds.  The only basis for such a claim would seem to have rested on Cronnelly's assertion that the Duhallow sept derived from the eldest son of Cormac Fionn.  In any case, O'Sullivan Mór refused to confer the white rod and Florence Mac Carthy became the Mór.  To our knowledge neither of the Duhallow Mac Carthys fought at Kinsale.  Dermod Mac Owen was imprisoned by the English before the battle and held for the duration of the Spanish interlude.  Cormac Mac Donogh, his cousin, was kidnapped by O'Neill and was killed in action in the Clare-Galway region.


Duhallow's most enduring link with the clan Mac Carthy remains that empty, roofless, achitectural gem, Kanturk Castle, on the banks of the River Brogeen on the road to Banteer.  It would appear that its construction was never completed.  Tradition tells us that it was begun in the reign of Elizabeth and its progress halted by Court order, on foot of alarmist reports from neighbouring English settlers.  Most serious historians nowadays consider that its commencement was after Elizabeth's time and that money troubles were the cause of its unfinished state.  The Duhallow MacCarthys had earlier castles at Kanturk, Curragh (Kanturk), Castlecor, Lohort and Dromsicane (Cullen).

Donal III (Domnall Ruad), King of Desmond, 1262-1302.  Donal III was first cousin of both Fingen V and Cormac V, and the eldest surviving son of Cormac IV.  Having acceded to the crown, he appears to have entered into a 'dynastic pact' with his first cousin Donal Oge MacCarthy, the only surviving son of Donal II, and brother of Fingen V and Cormac V.   Donal III granted his rivals large appanages or lordships in return for their recognition of his kingship.  Thus Donal Oge renounced all claim to the kingship for his posterity.  Donal III died in 1302.  The Annals of Connacht state that: "Domnal Ruad Mag Carthaigh, King of Desmond, the most generous and valorous, the most terrible and triumphant of the Gaels of all Ireland in fights and forays, died after a victory of repentance  this year (1302)."

Ist Lord Muskerry


MUSKERRY.  Scholars cannot agree on the precise origins of the Duhallow and Muskerry Mac Carthys.  O Murchadha says that the Muskerry sept are the descendants of Dermod, son of Cormac Mór, King of Desmond, who died  in 1359 3.  Both baronies were always regarded as being within the Mac Carthy Mór's domain, though part of Muskerry was held for a time by Richard de Cogan.  Today, Muskerry is divided East and West.  The ruling family built friaries and had castles throughout their tuatha: Kilcrea, Blarney, Cloghphilip, Ballea (Carrigaline), Carrigadrohid, Castlemore, Dooneen (Millstreat) and Dripsey.  Two of their properties became latter-day centres of Catholic education, at Carraig na bhFear and Drishane.  The last-named branch must surely be famous for the longevity of its taoisigh.  Drishane Castle was built in 1450 by Dermot, brother of Cormac Láidir, Lord of Muskerry.  Dermot's great-grandson Donogh was born in 1517 and died in 1639.  What social change that man must have witnessed!  Donogh's granson, another Donogh, of Dooneen, had the misfortune of losing Drishane after the wars of the 1640s.  He lived from 1619 to 1725.  His son, Donogh Og lived to be 96 years, dying in 1763.   Drishane later became the convent of The Congregation of the Holy Child.


The Lordship of Muskerry passed, after some intermissions, from Cormad Láidir (d. 1494) to his great-grandson Diarmuid Mac Taidhg.  After the latter's death in 1570, two of his brothers became taoisigh, a third brother being given the castle of Dooneen.  The last of these taoisigh, Callaghan Mac Taidhg, was ousted by his nephew, Diarmuid's son, Cormac of Blarney, with whome his cousin and namesake of Carraig na bhFear carried on a bitter feud.  The first-named won out and after 'surrendering', was regranted an English title to his lands.  He refused to join O'Neill's rebellion, was on the English side at Kinsale, but was then accused of having 'treasonable traffic with the Spaniards' and was imprisoned.   Later released, he joined O'Sullivan Bere in rebellion, submitted and was pardoned.  His son, Cormac Og, was created Viscount Muskerry and Lord Blarney, to be succeeded by Donogh, one of the leaders of the Catholic Confederacy 1642 - '52.  He lost all in 1650, surrendered at Ross Castle in 1652 and went to France, where he was created Earl of Clancarthy by Charles II in 1658, before being restored to his lands in 1661.  One of his sons, Justin, Lord Mountcashel, was famous amongst the 'Wild Geese', while his Jacobite grandson, Donogh, was indicted after the Boyne, imprisoned in the Tower, and pardoned but exiled.  The huge acres of Lord Muskerry's estate were confiscated and auctioned in 1702 in London.  The Mac Carthaigh 'Spáinneach' of Carraig na bhFear, later owners of Cloghroe and Knockavilla as well, were descended from the previously-mentioned cousin of Cormac Mac Diarmada.  This branch conformed to the Established Church, changed the name to Mac Cartie and, as such, held their lands until 1924, when they were sold to the Sacred Heart Missionaries.

Tadgh II (Tadg na Mainstreach MacCarthy Mór), King of Desmond,1390-1428.   He was the son of Donal V and came to the throne of Desmond in 1390.   None of the other members of the royal derbhfine challenged his title.   As Tadgh had no brothers, and his immediate cousins, the lords of Muskerry, Coshmang, Ardconaghty, and Ardtully, had already been provided with great appanages, none of the princes of the dynasty desputed his claims.  Tadgh II had three sons.  The eldest, Donal VI succeeded him and was ancestor of that branch of the royal house, which was extinguished for want of legitimate heirs on the death of Donal IX MacCarthy Mór in 1596.   Tadgh's second son, Cormac received the lordship of Kerslawny and was ancestor of that branch of the dynasty, which eventually succeeded to the chieftainship of the royal house.  The third son, Dermod, died 0without issue.  Tadgh II died in 1428.  The Annals of Inisfallen state that:  "Tadc MacCarthaigh reigned thirty-eight years, and of the foreigners and the Gaedil of his time he was the best, the greatest, .... and the  most reputed for drinking wine.  He died in his castle of Baile UÍ Chairpri and was buried in the same monastery."
