Branching out of the Race of Eoghan, son of Oilill Olum.
Here commences the genealogies and the branches of relationships of
the family of eoghan Mor son of Oilill Olum - as set out here; and
beside the other descendants of Oilill Olum.
Eoghan Mor son of Oilill Olum, had one son i.e., Fiacha Muilleathan
(i.e. Fiacha of the Flat head). This son was conceived as follows:
one night Eoghan went to the house of Dil of the Crecraighe tribe,
before going to the battle of Magh Mucruimbe. Dil then lived at
Carn Fhearadhaig in the territory of the Northern Deis. This Dil
then had a marriageable beautiful daughter called Muncha. While they
were drinking Dil, the Druid, asked Eoghan if he had a family. No, said
Eoghan. "Sleep with my daughter tonight," said the druid "and you shall
have a wonderful child."" Eoghan agreed with this and Dil went to his
daughter and said, "Cohabit with Eoghan tonight and there shall be
conceived a son and he shall be a king and his family and race shall be
a royal one afterwards and Eoghan shall be slain in the forthcoming battle
of Magh Muchraime.
Muncha lay with Eoghan that night, at the druid's directive. Eoghan went
off in the morning along with his kinsmen to join forces with Art son of
Conn (from Tara) and they went to the battle of Magh Muchruime. Afterwards
the druid and his daughter Muncha went to Western Magh Femhin, for there
was Eoghan's residence at Knockgraffon.
When the time came for the child to be born, the druid said, "Daughter, if
it is today that you shall bear the child, he shall be a druid; but if he
is not born until tomorrow, the child shall be king and his descendants
shall be a royal race."
Muncha said: "My son shall not be born until tomorrow so that he shall be
king. The daughter of Dil's then goes to the River Suir, to Ath Hisil on
the Suir. There was a great flagstone in the middle of the ford there - she
lay flat on the stone until daybreak on the following day.
It is time now, O daughter - said her father, "to bear the child." The
wonderful talented youth was then born, in the middle of the flagstone that
is Fiacha Muilleathan - father of all the eoghanachta (tribe of Owen). Noble
was the youth then born - Fiacha Fer da Liach i.e., Fiacha the Man of two
Sorrows; his father was slain the day after his conception, his mother on
the day of his birth.
Eventually Fiacha Muilleathan, son of Eoghan Mor, assumed the kingship
of the two Munsters and during his reign Cormac Ua Cuind, king of Ireland,
came (from Tara) with a hosting into Munster, demanding tribute from the
two provinces of Munster. Cormac besieged the Munstermen at Druim Damhaire
(Knockloag); this king weilded great power, both by the vastness of his
army and the power of his druids. Cormac had British druids weaving
their spells against the Munstermen, so that by necromancy they had dried
up all the wells and rivers of Munster, so that the people and their lands
were in danger of death from the want of water.
Then Fiacha Muilleathan sent for Mogh Ruith son of Fergus, the best
druid to be found in Ireland. Mogh Ruith then lived in Oilen Dairbhre
(Valentia Island) in his old age, blind and decrepit, as he had outlived
nineteen kings of Ireland:- from the time of Roth mac Rioghuill (the
druid who had trained Mogh Ruith in sorcery) to the time of Cairbre
Lifechair son of Cormac mac Airt.
Mogh Ruith then came to meet Fiacha Muilleathan and the Munster nobles
and they complained about what the druids of Leath Cuinn (Northern half
of Ireland) had done to them. he undertook to oppose their magic spells, and
he chose the territory of Fir Mhwige (Fermoy) as his reward. Mogh Ruith
then overcame the druidery of Cormac and they defeated Cormac's forces
routing them from Knockling to Tara with a great massacre. Fiacha
Muilleathan the Munster king did not leave Leath Cuind until he got hostages
and homage from Cormac mac Airt; as the poet Feidhlime mac Crimithann
Good was the king Fiacha Muilleathan
A great territory the Half over which he ruled
He brought hostages from Tara the Strong
To Rathfuim to Rath Naoi
Though he was great; Cormac Ua Cuinn
He bowed to the king of Tir Duinn (Munster).
Fiacha Muilleathan had three noble sons, Oilill Flann Mor and
Oilill Flann Beag and Deachluath. The latter, Deachluath is ancestor of the
tribe called Ui Fiachach Eile (in north-east of Tipperary - Thurles and
Roscrea) and Oilill Flann Mor left no issue.
The family of Oilill Flann Beag.
Oilill Flann Beag had four sons, i.e.,
1. Lughaid, ancestor of all the Eoghanachta;
2. Fiodach, father of Crimthann;
3. Daire Cearba from whom was the Ui Liathain;
4. Maine Munchaoin from whom the Ui Fidgeinte; (the O'Donovans
and O'Collinses of mid and west Limerick)
Fiodach, to him was son Criomthann Mor mac Fiodhaig from whom is the
tribe Clann Crimthann. He was king of Ireland and Britain.
It is this Crimthann who took the fortress of Doire Da Broc from the sons
of Eochaid Mugmeadhon (of the kings of Tara) ie., from Brian, Fiachra, Oilill
and Feargus. Crimthann's sister Muingfionn was mother of those four sons.
So that her son, Brian, would ge the kingship of Ireland, she plotted to
poison her brother, Criomthann; the latter died of that poisonous drink;
and Mungfionn herself died as well at Inish Donglais on the Moy (Co. Mayo)
- as she tasted the drink in order to induce her brother to drink from it.
Crimthann having drunk it came to Sliabh Uidhe on Riogh "The Mountain of the
King's Death" (now Cratloe Hill, Co. Clare) and there expired.
The four above names sons of Oilill Flann Beag divided Munster between
them as follows.
From Comar no dTre in Utsge (Waterford Harbour) to Belach Conglais
(Cork Harbour) - Luguid ancestor of the eoghanachta and Fiodach father of
Criomthann took this half; from Belach Conglais (Cork Harbour) to Limerick -
Daire Cearba and Maine Muncharim to this other half.
These latter two Daire and Maine were born at one birth and concerning them
(before birth their mother saw this vision: they were back to back in her womb
and a black chafer between them. This was interpreted as follows: The tribe
of Mogh Ruith the druid was the chafer placed between the Ui Liathain and the
Ui Fidgeinte so that neither could come to the help of the other.
Lughaid son of Oilill Flann Beag (ancestor of all the Eoghacbhe) had
1. Lughaid, from whom were the little sept of Ui Luighdheach Eile
(at Bomisoleigh, Co. Tiperrary)
2. Cathfaidh, from whom were the Ui Cathfhaid Cuile (these were
scattered about N.W. Tipperary)
3. Corclosadh, the third son. The three above had as mother Dail, dau.
of Fiacha, son of Niall, King of Eile.
4. Corc, son of Luighaid, the fourth son, from him the Eoghanachta and
kingship of Munster.
Corc son of Lughaid.
The birth of Corc son of Lughaid. While Lughaid was in the kingship of
Munster, Corc was born. Lughaid's wife then was Daoil daughter of Fiacha
King of Eile. It happened that a woman satirist came to the king's house
in Feimhin (South Tipperary plain). Doilg Ireithneach was her name.
She put a desire to cohabit with her into the king's mind and born to them
whom they called Conall son of Lugaid.
And why did he get the name Corc?
the persons who fostered Conall were Maghlar Dearg of the Corca Oiche tribe
(Abbeyfeale district) and Torna Eigeas the poet of the Ciaraigh Luachra (of
Kerry) - they reared him in the house of Crimthann Mor now of Fiodhach.
There were Sorceresses in Munster at that time, destroying youths and every
newborn child they choose to destroy. Some of these Sorceresses led by
Feidhlim daughter of Mothair came to the house when the infant Corc was. The
nurses who were in the house hid the youth under an upturned cauldron which
was in the house. Said one of the Sorceresses: Whom shall we destroy of the
people of this house. Another said: None but whoever is hid beneath the
cauldron. After that a spark shot out of the fire and pitched in the youth's
ear so that it became purple (Corcra); hence he was called Corc.
The brancing-Out of the Descendants of Corc, Son of Lugaid, as follows:
Corc, son of Lugaid, had eleven sons.
1. Nadfraoich, from whom were the Eoghanacht of Cashel and the
Eoghanacht of Glanworth and the Eoghanacht of Aine (Knockeiney)
and the Eoghanacht of Airthir Cliach (Tipperary town district).
2. Cas, son of Corc, from whom were the Eoghanacht Raithlenn and
Ui Eachach Mumhan (the O'Mahonys, O'Donoghues etc. in West Cork)
3. MacBroic from whom were the Ui Mhic Broic (unkown).
4. Ciar from whom were the Ui Mhic Ceir (an umimportant sept on
the south side of Cork City)
These four were sons borne to Corc by Aoibhinne, daughter of Aonghus
folg, king of Corca Louighodhe (the O'Driscoll sept in diocese of
Ross, West Cork).
Corc, however, had four sons by Mungfionn daughter of Feredhach, King
of the Picts of Scotland.
5. Cairbre Cruithneachan, from whom were the Eoghanacht of Magh
Geirginn in Scotland.
6. Maine Leambna (i.e., Maine of Leven at Loch Leven in Scotland)
from whom were the Leamhnaig of Scotland.

border), from whom were the Eoghanacht of Loch Lein (Killarney)
and the Aos Aiste (Tuosist) Aos Alla (in Dhallow) and the
Aos Greine (at Pallasgreen, Co. Limerick).
8. Croanan from whom were the Cuircus sept of Westmeath. The two
Cairbres were twins. Two of the latter four remained in Scotland
in the hereditary paterning of their mother, of the Picts of
Scotland, i.e., Cairbre Cruithneacain in Magh Geirrgimn (Kincardine)
and Maine Leambna in Magh Leambna (Leven).
This Aoibhinn, daughter of Aonghus Bolg and the first wife of
Cork, saw a vision the first night while she lay with the king of
Cashel; She though she bore four whelps - the first Nad Fracich, she
bathed in wine; the second Cas, in ale, the thired, MacBroic in new
milk, and the fourth, MacCiair, in water. Then came a fifth whelp
and he was bathed in blood - Cairbre Cruithneacain and that he bit
the nipples off her breasts then.
She also saw the vision in another form: four birds in a nest (in
Cashel). Two other birds came to ireland and fought with them; then
one went straight westwards and the other east. Of the four in the
nest, three went ot the southwest while one remained in the nest with
the queen - Nad Fraoich son of Corc was the one who stayed behind -
he was king of Cashel of that queen's family.
Cas and MacBroic and MacCiair were the three who went southwest
(west Cork). As to the two birds who came from other parts - the one
who went westwards was Cairbre Luachra who went west over Luachair
Deadhaid (Slieveloughra) and was ancestor of Ui Cairbre Luachra i.e.,
the Eoghanacht of Loch Lein (Killarney); and the bird who went
eastwards was Cairbre Cruithneacain who went east to Scotland. Some
say that these two Cairbres were but one and that Cairbre Cruitnechan
(i.e., the son of the Pictish woman) was ancestor of the Eoghanacht of
Loch Lein (the O'Moriarty sept).

This Suilleabhain's real name was Eochaidh and how did the by-name
Once there came a British druid on a trip to Ireland. Lobhan Draoi his
name. he came to Eochaid and rendered him much services at the time;
Eochaid offered him many valuables and gifts in payment, but the druid
would not take any reward but sought the one eye which was in Eochaid's
head and for his honour and fearing that the druid would satirize him he
gave it to him. St. Ruadhan was at that time with Eochaid and was witness
of this unreasonable request. He said: "I will it, if the Lord wills it.
That your eye shall go into the head of Eochaid in place of his own eye."
God granted this miracle for Ruadhan. The eyes of Lobhan were transferred
to Eochaid and he saw with them; hence he was called Suilleabhain (the
eyes of Lobhan).
