The History of Ireland - GENEALOGIES



Very few early or reliable MSS. of Keating's History give the genealogical and synchronistic sections in a complete and satisfactory manner. In some cases the MSS. are torn or otherwise defective in these sections. Good MSS, otherwise reliable, have curious scribal interpolations in the body of the genealogies. Thus MS. M3 (King's Inns) is an excellent MS. for the body of the history but rather unsatisfactory in the genealogies and synchronisms as I discovered after I had copied the entire section. O'Naughton's copy is also largely interpolated in the genealogies. After a careful examination of the principal MSS. used in the preparation of the text of the History I adopted the version of the genealogies and synchronisms given in M1 (H 5 26 T.C.D.) regarding it as the most complete and satisfactory copy of these sections that has come down to us. Of course the archaisms of this MS. are scarcely noticeable in the genealogical section.

I have supplied variations from M2 (H 5 32 T.C.D.), Fr (A 14, Franciscan Library, Merchants' Quay), F2 (A 15, same Library).

I have also supplied variants from other sources but chiefly from Mac Firbis's Book of Genealogies, R.I.A. (McF.) and from O'Clery's Genealogies, R.I.A. (O'Cl.). Both of these works are practically contemporaneous with the work of Keating, and are, moreover, the result of special genealogical study. I have therefore given their lists as variants.

There are 16 genealogies in all, marked by the letters of the alphabet A to P inclusive, while Q is added as an important variant of C. Nearly all the genealogies are traceable to Milidh Easpainne and thence by an easy ladder to Adam, in whom all the lines meet. I have marked Adam as number one, and in the line of descent from him, as given in A, Milidh Easpainne numbers 36, and Oilill Olom (sprung from Eibhear) 87. In the line of descent from Adam through Milidh Easpainne and Eireamhon (as expanded in full in O'Clery's Genealogies, p. 7) Niall Naoighiallach numbers 90, and Cobhthach Caol mBreagh 60 and Ughaine Mor 59, while in the line of descent from Adam through Fearghus mac Roigh (Fearghus s. of Rossa Ruadh), Fearghus numbers 36 (O'Clery's Genealogies, pp. 187, 203, etc.)

In each genealogy I have given to the name nearest to Adam to which the genealogy is brought, the number to which it is entitled in the main line to which it belongs, and have numbered the lists onwards, starting from such number. Thus B is brought to Oilill Olom to which name the number 84 is attached in A.. H is brought to Eochaidh Muighmheadhoin, to which name the number 89 corresponds in O'Clery's full genealogy of the descent from Adam through Eireamhon (O'Clery's Genealogies. p. 7), etc. In N. the number 84a has been introduced for convenience.


Some seanchas assert that there are in Ireland twelve tribes of the Saorchlanna or true nobility of the Gaels, namely six tribes in Leath Cuinn and six in Leath Mogha. Here are the six tribes of Leath Cuinn, namely Dal gCuinn Dal gCein Dal nAruidhe Dal bhFiatach Dal Riada and Dal Niadh Cuirb. The six tribes of Leath Mogha are Dal nEoghain Dal bhFiachach Dal gCeide Dal Dairine Dal mBairdine and Dal gCais.
Still this is not the order we shall follow in giving the branchings of the sons of Milidh, but we shall follow up the posterity of those three sons of Milidh of Spain who have left issue, namely Eibhear, Ir and Eireamhon, and also that of Lughaidh, son of Ioth, who was son of a brother of Milidh's father.
Know, O reader, that there are in Ireland six tribes of the Aitheachthuaith or Daorchlanna whose genealogy it is not right to trace, though a section of them are Gaels while the others are not Gaels.
The first of these tribes is the remnant of the Fir Bolg and of the Tuatha De Dhanann.
The second tribe consist of those who left their own territory and being descended from Saorchlanna submitted to a servile tribute from another race.
The third tribe consists of that body of Saorchlanna whose territory had been made into sword-land and who remained therein in slavery under the sway of their enemy.
The fourth tribe consists of that body of Saorchlanna who fell into slavery through their own misdeeds and who forfeited their blood and lands by law.
The fifth tribe are those who sprang from foreign soldiery, namely from mercenaries from other lands who left issue in Ireland.
The sixth tribe consists of the descendants of the slaves who came to Ireland with the sons of Milidh.
Now what surprises many is how it could come to pass that no portion of the descendants of the Saorchlanna who came with the sons of Milidh to Ireland should survive. To this my reply is that Tuathal Teachtmhar after he had assumed the sovereignty of Ireland visited them with great slaughter because of their treachery towards the Saorchlanna of Ireland as we have stated. For he defeated them in twenty-five battles in Ulster, in twenty-five battles in Connaught, in twenty-five battles in Leinster, and in thirty-five battles in Munster; and if after this some remnant of them has survived no seancha ought, nor would it be possible for him, to follow up and search out the branching of the genealogy of these or of any of the five other tribes which we have enumerated above; and should any untutored seancha attempt to trace their genealogy whatever statements he might make would have no claim to be regarded as history.
Understand, O reader, that we shall set down here the leading genealogical branches of the true Gaelic nobility, and that we shall begin with the race of Eibhear because of their seniority. Nevertheless, O reader, you should know that we shall introduce into the direct line branches that did not spring from its senior founder, but whose claim arises from the noble exploits in which their ancestors excelled their seniors in birth. Indeed the sovereignty of Ireland and of the provinces was more frequently held by members of junior than by those of senior branches. Here are proof and examples of this:
It is obvious that there were more monarchs of Ireland of the race of Eireamhon, the junior, than of the race of Eibhear, the senior; and that there were more monarchs of Ireland of the posterity of Cobhthach Caol mBreagh, son of Ughaine, the junior, than of the posterity of Laoghaire Lorc, the senior; and that there were more monarchs of Ireland of the posterity of Niall Naoighiallach son of Eochaidh Muighmheadhoin than of the posterity of the four sons of Eochaidh who were seniors to him; and that there were more kings of Connaught of the posterity of Duach Galach, the junior of the sons of Brian son of Eochaidh, than of the posterity of the twenty-three who were seniors to him, and that there were more kings of Leinster of the posterity of Fiachaidh Aiceadha son of Cathaoir Mor, the youngest of the sons of Cathaoir, than of the posterity of the nine others who left issue. And thus it appears that it was not by right of seniority that kings assumed the sovereignty of Ireland or of the provinces, but rather by the greatness and nobility of their deeds; and hence I mean to unfold here the family branches and genealogical ramifications of each division of them in due order and succession and to trace each offshoot to its own particular place in the branch.
Here follow the branching of the race of Eibhear; and first of the posterity of Eoghan son of Oilill Olom, senior of the family of Eibhear.
Now Oilill Olom had three sons who had issue, namely Eoghan Mor, Corbmac Cas and Cian. All that survive of the race of Eibhear are descended from these three.


122 Domhnall the first earl, son of
121 Domhnall an Druimnin, son of
120 Corbmac Ladhrach, son of
119 Tadhg Liath, son of
118 Domhnall an Dana, son of
117 Tadhg na Mainistreach, son of
116 Domhnall. Brother to this Domhnall was Diarmuid Mor of Muscroighe from whom descended Lord Muscroighe and all who sprang from him. Another brother of his was Eoghan of Bord Mainge whence the Carrthaigh of Cois Mainge are descended; son of
115 Corbmac, son of
114 Domhnall Og, from whom are descended Clann Domhnaill Ruaidh. From the progeny of Diarmaid of Traigh Li, brother to this Domhnall Og, is sprung Mac Finghin of Ceithearn; son of
113 Domhnall Ruadh na n-oighbhreath, son of
112 Cormac Fionn. From this Cormac Fionn are descended Clann Charrthaigh of Alla and the princes of Desmond; and from a brother of this Cormac Fionn is sprung Mag Carrthaigh Riabhach and all who are descended from him; son of
111 Domhnall Mor na Cuirre, son of
110 Diarmuid of Cill Badhaine from whom are sprung Clann Taidhg Ruaidh of Scairt; son of
109 Cormac of Magh Teamhnach. From Tadhg brother of this Cormac is sprung Mac Amhlaoibh; son of
108 Muireadhach, son of
107 Carrthach, whence Clann Charrthaigh, son of
106 Saoirbhreathach. Brother to this Saoirbhreathach was Murchadh whence spring Siol gCeallachain son of

104 Ceallachan of Caiseal, son of
103 Buadhachan, son of

101 Artghal, son of
100 Sneadhghus. Brother to this Sneadhghus was Foghartach and son to Foghartach was Fionghuine from whom Muinntear Fhionghuine are called; son of
99 Donnghal, son of
97 Natfraoich, son of
98 Faolghus, son of
96 Colga, son of
95 Failbhe Flann. Brother to this Failbhe Flann was Finghin son of Aodh Dubh from whom are sprung O Suilleabhain Mor and O Suilleabhain of Bearra. The Book of Munster says that Finghin was senior to Failbhe and that for that reason the seancha composed the following stanza on Finghin's being in the sovereignty of Munster before Failbhe, on account of his seniority to him:--

To be without Finghin, to be without Mor
To Caiseal is a cause of grief;
It is as if there were no king
If Failbhe Flann is to be king.

However since the descendants of Failbhe excelled those of Finghin in prowess and nobility of deeds they are made founders in the genealogy here; son of
94 Aodh Dubh, son of
93 Criomhthann, son of
92 Feidhlimidh. Brother to this Feidhlimidh was Eochaidh Fionn from whom is sprung O Caoimh, and another brother to him was Eanna whence spring Muinntear Dhalaigh of Munster; son of
91 Aonghus, son of
90 Natfraoich.

89 Corc, son of
88 Lughaidh. Brother of this Lughaidh was Daire Cearb from whom are sprung O Donnabhain and
O Cuilein of Cairbre; son of
87 Oilill Flann Beag. From the progeny of Fiachaidh Fighinnte son of Daire Cearb son of OiLill Flann Beag are sprung Muinntear Aicheir, Muinntear Mhiadhachain and Clann Mhic Dabhith in Thomond; son of
86 Fiachaidh Muilleathan, son of

The branching of the race of Eireamhon.

Now Ughaine Mor is the ancestor of all that survive of the race of Eireamhon, and all his sons went without issue except two, namely Laoghaire Lorc and Cobhthach Caol mBreagh. Of the posterity of Laoghaire Lorc are the descendants of Eireamhon in Leinster and of the posterity of Cobhthach are the descendants of Eireamhon in Leath Cuinn.

This Mongfhionn was sister to Criomthann, son of Fiodhach, king of Ireland. The fifth son of Eochaidh was Niall; Cairionn Chasdubh daughter of the king of Breatain was his mother, and although Niall was the youngest of the five sons we have placed him first in the genealogy, since he was the most renowned of them and as it was from his descendants the greater number of the kings of Ireland were drawn. Of the four above-named there are two without issue, so far as I can find, namely Fearghus and Oilill. But of each of the two brothers who left issue namely Brian and Fiachra we shall give here the branching.
