Dúngal mac Cellaig
Dúngal mac Cellaig( died 772) was a King of Osraige in modern County Kilkenny.
He ruled from 770 to 772.
He was of the dynasty known as the Dál Birn that ruled over Osraige in the early Christian period and was the son of Cellach mac Fáelchair( died 735), a previous king.
The Osraige plunged into civil war upon the death of Anmchad mac Con Cherca after 761.
Tóim Snáma mac Flainn was opposed by the sons of Cellach, presumably Dúngal and in 761 they were defeated by Tóim Snáma and were put to flight.
In 770 Tóim Snáma was slain presumably by Dúngal.
Conall Cóel
Conall mac Máele Coba, called Conall Cóel,( died 654) was an Irish king and is said to have been High King of Ireland.
Máel Coba mac Áedo
Máel Coba (died 615) was a High King of Ireland.
Máel Coba was the son of Áed mac Ainmuirech (died 598) and brother of Domnall mac Áedo (died 642), both also reckoned High Kings of Ireland.
They belonged to the northern Cenél Conaill branch of the Uí Néill.
Máel Coba became chief of the Cenél Conaill upon the death of his brother Conall Cú mac Áedo in 604.
The high kingship of Ireland tended to rotate between the Cenél nEógain and Cenél Conaill branches from the mid 6th century.
He follows Áed Uaridnach in the king lists, and is followed by Suibne Menn, both of the neighbouring Cenél nEógain, but of rival lines.
He ruled from 612-615
In 615 Máel Coba was defeated and slain by Suibne Menn at the Battle of Sliab Truim in Tyrone.
Suibne Menn apparently installed Óengus mac Colmáin as High King, at least in name.
He had two sons who were counted as joint High Kings in some sources, Cellach (died 658) and Conall (died 654).
Dúnchad mac Cinn Fáelad, abbot of Iona, (died 717) is recorded as Máel Coba's grandson.
Cellach mac Máele Coba
Cellach mac Máele Coba (died 658) was an Irish king and is said to have been High King of Ireland.
Cellach was the son of Máel Coba mac Áedo (died 615) and belonged to the Cenél Conaill branch of the northern Uí Néill.
According to the Irish annals derived from the "Chronicle of Ireland", he may have been High King, jointly with his brother Conall Cóel, following the death of his uncle Domnall mac Áedo in 642.
The "Annals of Ulster" for 643 say:Here there is doubt as to who reigned after Domnall.
Some historiographers say that four kings, namely Cellach and Conall Cóel and the two sons of Áed Sláine, namely Diarmait and Blathmac, ruled in shared reigns.
All four putative successors to Domnall had been his allies at the great Battle of Mag Roth in 637, where Congal Cáech was defeated at the authority of the Uí Néill re-established, and it is not implausible that all four ruled together.
He ruled from 643-654
The king lists give Cellach and Conall as reigning before Diarmait and Blathmac.
Both Cellach and Conall are omitted from the earliest king list-a late 7th century poem "Baile Chuinn".
A challenge to their authority occurred in the north when their cousin Óengus mac Domnaill was defeated and killed at the Battle of Dún Cremthainn by Conall and Cellach in 650.
Conall Cóel was killed by Diarmait in 654 while Cellach died in 658, perhaps at Bru na Bóinne.
It is possible
Cellach had been captured by Diarmait in 654 and died a prisoner.
His daughter Cacht ingen Cellaig married Máel Dúin mac Máele Fithrich (died 681) King of Ailech.
Máel Dúin mac Máele Fithrich
Máel Dúin mac Máele Fithrich( died 681) was a King of Ailech and head of the Cenél n Eógain branch of the northern Uí Néill.
He had married Cacht ingen Cellaig, daughter of the high king Cellach mac Máele Coba( died 658) of the Cenél Conaill and their son Fergal mac Máele Dúin( died 722) was high king of Ireland.
He was the son of Máel Fithrich mac Áedo( died 630) and grandson of the high king Áed Uaridnach( died 612).
He ruled as King of Ailech from circa 668-681.
The annals record the destruction of Ailech in 676 by the high king Fínsnechta Fledach( died 695) of the southern Uí Néill who appears to have asserted his authority in the north.
Máel Dúin was active increasing the power of the Cenél nEógain.
In 677 he slew Dúnchad son of Ultán, king of Airgialla- of the Uí mac Carthainn, near Lough Foyle, Tirkeeran in modern County Londonderry- in Dún Forgo.
In the summer of 681 he was successful over Dúngal Eilni mac Scandail of Dal n Araide and Cenn Faelad mac Suibni of the Cianachta Glenn Geimin( Keenaght, County Londonderry) at what was called the burning of the kings at Dún Ceithirn( in barony of Coleraine, in modern County Londonderry).
He belonged to the Cenél maic Ercae branch of the family.
The rival Cenél Feradaig branch dominated the kingship for most of the 7th century.
At the beginning of winter 681 he was defeated and slain at the Battle of Bla Sléibe( in modern County Londonderry) by the Ciannachta of Glenn Geimin and by Fland mac Máele Tuile( died 700) of the rival Cenél Feradaig.
