He was the son of Congal mac Áedo Sláine( died 634), a previous king of Brega.
The territory of Brega that he ruled was called Cnogba( Knowth) or North Brega which he ruled from 634 to 662.
He ruled during a time when his uncles Diarmait mac Áedo Sláine( died 665) and Blathmac mac Áedo Sláine( died 665) were jointly High King of Ireland.
The annals record a battle between Blathmac and the adherents of Diarmait at the Battle of Ogomain in 662.
Conaing was slain fighting on the side of Blathmac in this civil war.
His allies, Ultán son of Ernaine, chief of Ciannachta, and Cenn Fáelad son of Gerthide, chief of Ciannachta Arda were also slain.
His descendants ruling at Cnogba were known as the Uí Chonaing.
His sons Congalach mac Conaing Cuirre( died 696) and Irgalach mac Conaing( died 702) were also kings of Brega.
Irgalach's son Cináed( died 728) was late High King of Ireland, the penultimate Uí Chonaing High King, the last being Congalach Cnogba in the 10th century.
His daughter Caintigern married Cellach Cualann( died 715), the Uí Máil king of Leinster and was mother of Saint Kentigerna.
Diarmait Dian
Diarmait Dian mac Airmetaig, also Diarmait Guthbinn,( died 689) was King of Uisnech in Mide of the Clann Cholmáin.
He was the grandson of Conall Guthbinn mac Suibni( died 635), a previous king.
His father Airmetach Cáech was slain at the Battle of Mag Rath in 637.
Diarmait ruled from 653 to 689.
The feud between Clann Cholmáin and the Síl n Áedo Sláine of the early 7th century had ended in victory for the Síl n Áedo Sláine who dominated the high kingship of Ireland in the second half of the 7th century.
They began to feud among themselves, and Clann Cholmain was caught up in the feud as well.
In 662, a member of the cousin line of Clann Cholmáin Bicc, Fáelch ú mac Máele Umai was slain at the Battle of Ogamain fighting on the side of Conaing Cuirre mac Congaile of Cnogba and Blathmac mac Áedo Sláine( died 665) while fighting the adherents of Diarmait mac Áedo Sláine( died 665).
Diarmait himself was killed in 689 as part of the old feud by Áed mac Dlúthaig( died 701) of the Fir Cúl Breg sept of Síl n Áedo Sláine.
Áed's grandfather Ailill Cruitire mac Áedo Sláine was slain in battle by Diarmait's grandfather Conall Guthbinn in 634.
According to the" Book of Leinster", Conall Guthbinn was killed by the High King Fínsnechta Fledach mac Dúnchado( died 695) of Brega.
Diarmait's sons included: Diarmait's grandson Domnall Midi mac Murchado( died 763) was a high king of Ireland.
Niall mac Cernaig Sotal
Niall mac Cernaig Sotal( died 701) was a king in southern Brega of the Uí Chernaig sept of Lagore of the Síl n Áedo Sláine.
He was the grandson of the high king Diarmait mac Áedo Sláine( died 665).
His father Cernach Sotal had died during plague years in 664.
Conall Guthbinn
Conall mac Suibni( died 635), called Conall Guthbinn, Prince of Meath, was King of Uisnech in Mide of the Clann Cholmáin.
He was the son of Suibne mac Colmáin( died 600), a previous king.
He ruled from 621 to 635.
His byname Guthbinn meant" sweet voiced".
His father Suibne had been killed in 600 by his uncle Áed Sláine mac Diarmato( died 604) eponymous ancestor of the Síl n Áedo Sláine.
This set off a feud between the Clann Cholmáin and Síl n Áedo Sláine and in 604 a battle was fought in Faithche Mic Mencnain on the shore of Loch Semdid( Lough Sewdy),( Ballymore Loughsewdy in modern County Westmeath).
During the battle Conall saw his foster brother Áed Gustan slaying Áed Sláine.
Áed Rón of the Uí Failge and Áed Buide, king of Tebtha, Áed Sláine's allies, were also slain.
The" Annals of Ulster" record:
It was no time when counsel prevailed, for the warriors beyond Tuirbe: Conall slew Áed of Sláine, Áed Sláine slew Suibne.
Conall succeeded as King of Uisnech in 621 on the death of Óengus mac Colmáin, son of Colmán Bec. In 622, during the Battle of Cenn Deilgthen( modern Kildalkey in County Meath), Conall defeated a rival faction of cousins led by two sons of Librén, son of Illand, son of Cerball.
Illand was the brother of Conall's great- grandfather the high king Diarmait mac Cerbaill( died 565).
Domnall Brecc( died 642), later king of Dál Riata fought alongside Conall.
In 633, at the Battle of Áth Goan, west of the Liffey, Conall allied with Faílbe Flann mac Áedo Duib( died 637), the king of Munster, to assist Fáelán mac Colmáin( died 666?) of the Uí Dúnlainge in defeating and slaying Crimthann mac Áedo of the Uí Máil, acquiring the throne of Leinster.
The Clann Cholmain assisted the Ui Dunlainge in their rise to power, neutralizing the border situation with the Ui Failgi, as the Ui Dunlainge carried out their rivalry with the Síl n Áedo Sláine.
Fáelán mac Colmáin married Conall's sister Uasal ingen Suibni( died 643).
In 634, at the Battle of Loch Trethin at Fremainn( Lough Drin, .75 miles northeast of Cullionbeg, County Westmeath), Conall slew Congal mac Áedo Sláine, King of Brega, and his brother Ailill Cruitire, continuing the feud with the Síl n Áedo Sláine.
In 635 Diarmait mac Áedo Sláine( died 665) killed Conall in the house of Nad Fraích's son.
Conall's son Airmetach Cáech was slain at the Battle of Mag Rath( modern day Moira, County Down) in 637 fighting for Congal Cáech of Ulaid and against the High King Domnall mac Áedo( died 642) of the Cenél Conaill.
Airmetach's son Fáelchú was also slain in this battle.
Airmetach's other son, Diarmait Dian mac Airmetaig Cáech( died 689), was a King of Uisnech.
Áed Sláine
Áed mac Diarmato (died 604), called Áed Sláine (Áed of Slane), was the son of Diarmait mac Cerbaill.
Legendary stories exist of Áed's birth.
Saint Columba is said to have prophesied his death.
His descendants, the Síl nÁedo Sláine—the seed of Áed of Slane—were prominent in 7th and early 8th century Ireland.
Áed mac Dlúthaig
Áed mac Dlúthaig( died 701) was a King of Fir Cúl in Brega of the Síl n Dlúthaig sept of the Síl n Áedo Sláine of Brega.
He was the grandson of Ailill Cruitire mac Áedo Sláine( died 634), a king of Brega.
Congal mac Áedo Sláine
Congal mac Áedo Sláine (died 634) was a King of Brega from the Síl nÁedo Sláine branch of the southern Ui Neill.
He was the son of the high king Áed Sláine mac Diarmato (died 604).
His father had treacherously slain his nephew, Suibne mac Colmáin (died 600) of the Clann Cholmáin and was then himself slain in battle by Suibne's son Conall Guthbinn setting off a feud among the southern Ui Neill.
The date of Congal's accession to Brega is not stated in the annals.
His brother Conall Laeg Breg was slain in the Battle of Odba by Óengus mac Colmáin Bec (died 621) in 612.
In 634 Congal and his brother Ailill Cruitire were defeated and slain at the Battle of Loch Trethin at Fremainn (Loch Drethin at Frewin Hill, Co.Westmeath) by the same Conall Guthbinn who had slain their father.
Congal is recorded as king of Brega in the annals regarding this event.
Congal's son Conaing Cuirre (died 662) was also a king of Brega and ancestor of the Uí Chonaing of Cnogba (Knowth) or North Brega.
Ailill Cruitire
Ailill Cruitire mac Áedo Sláine( died 634) was a King of Brega from the Síl n Áedo Sláine branch of the southern Ui Neill.
He was the son of the high king Áed Sláine mac Diarmato( died 604).
His byname meant" harper".
The exact date of his accession to Brega is not mentioned in the annals.
He was contemporary to his brother Congal mac Áedo Sláine, who was called King of Brega in the annals, whereas Ailill was not.
The annals mention that in 634 Ailill and his brother Congal were defeated and slain at the Battle of Loch Trethin at Fremainn( Loch Drethin at Frewin Hill, County Westmeath) by the same Conall Guthbinn of the Clann Cholmáin who had slain their father.
Congal is recorded as king of Brega in the annals regarding this event, Ailill is not.
A poem in the" Book of Leinster", however, claims that Ailill was slain at the Battle of Áth Goan in western Liffey during a Leinster civil war in 633.
The victor was again Conall Guthbinn and his ally Fáelán mac Colmáin( died 666?) of the Uí Dúnlainge.
Ailill's son Dlúthach was ancestor of the Síl n Dlúthaig sept, or as Fir Cúl Breg, men of the churches of Brega.
His grandson Áed mac Dlúthaig( died 701) was a king of Fir Cúl.
Óengus mac Colmáin
Óengus mac Colmáin Bec( died 621) was an Irish king.
He was the King of Uisnech in Mide from 618 to 621.
He belonged to the southern Uí Néill.
According to the genealogies, he was a son of Colmán Bec( died 587), son of Diarmait mac Cerbaill( died 565).
The later Caílle Follamain traced their descent through Óengus.
Before acquiring the rulership of Uisnech, the annals record Oengus' involvement in the feud between the rival midland dynasties of Clann Cholmáin and Síl n Áedo Sláine.
In 612 he won the Battle of Odba( near Navan, Co. Meath) in which Conall Laeg Breg mac Áedo Sláine was slain.
This battle may have been caused by Conall's claims to succeed Áed Uaridnach as high king who died in 612.
He acquired the throne of Uisnech in 618 succeeding Fergus mac Colmáin.
According to the" Annals of Ulster", Oengus was killed in 621.
According to entries in the Irish annals reporting Óengus's death in 621, which incorrectly call him a son of Colmán Már, he was" regis Nepotum Neill" or" ríg h- Úa Neill", that is king of the Uí Néill.
This appears to be synonymous with the alternative titles of High King, King of Ireland, or that King of Tara.
It is suggested that the explanation for this is that when Suibne Menn killed Máel Coba mac Áedo in 615, he supported Óengus's claims rather than taking power himself, or perhaps that Óengus was a deputy king in the south.
The king list in the" Baile Chuind", created in late 7th century during the reign of the southern Uí Néill king Fínsnechta Fledach, apparently lists an Óengus — Glorious Óengus—as king following Suibne Menn.
Another king list of Marianus Scotus includes Óengus as a high king.
His sons Máel Umai mac Óengussa and Colgu mac Óengussa were slain, as part of the southern Uí Néill feud, at the Battle of Cúil Caeláin in 635, by Diarmait mac Áedo Sláine( died 665).
His grandson, Fáelch ú mac Máele Umai was slain at the Battle of Ogamain in 662 fighting on the side of Conaing Cuirre mac Congaile of Cnogba and Blathmac mac Áedo Sláine( died 665) versus the adherents of Diarmait mac Áedo Sláine.
