Domnall mac Muirecáin
Domnall mac Muirecáin (died 884) was a King of Leinster of the Uí Fáeláin sept of the Uí Dúnlainge branch of the Laigin.
This sept had their royal seat at Naas in the eastern part of the Liffey plain, Airthir Liphi.
He was the son of Muirecán mac Diarmata (died 863), a previous king.
There is much confusion in the king lists during this period for Leinster.
Francis John Byrne suggests that the root of this apparent confusion lay in the fact that the Uí Dúnlainge kings exercised little real authority due to the aggressions of their western neighbour Cerball mac Dúnlainge (died 888), King of Osraige.
Cerball, while unable to install himself as king of Leinster, was able to prevent any rival king exercising real power there.
Domnall would have succeeded his father as head of the Uí Fáeláin sept in 863.
His predecessor as King of Leinster, Ailill mac Dúnlainge of the Uí Muiredaig sept had died in 871, however Muiredach mac Brain (died 885) of the Uí Dúnchada sept is associated with the Leinster forces in association with events in 870 and 875.
According to the "Chronicum Scotorum" and other Irish annals, Domnall assumed the kingship of Leinster in 880.
This would place his effective reign in 880-884.
In 874 the high king Áed Findliath (died 879) had invaded Leinster in an attempt to impose his authority and he plundered the country and burned churches including Cell Ausili.
In 880 the new High King Flann Sinna (died 916) attacked Leinster and took hostages imposing his authority.
In 884 Domnall was killed by his own associates.
His brother Cerball mac Muirecáin (died 909) became King of Leinster in 885.
Muirecán mac Diarmata
Muirecán mac Diarmata (died 863) was a King of Leinster of the Uí Fáeláin sept of the Uí Dúnlainge branch of the Laigin.
This sept had their royal seat at Naas in the eastern part of the Liffey plain, Airthir Liphi.
He was the son of Diarmait mac Ruadrach (died 832), King of Airthir Liphi.
His uncle Muiredach mac Ruadrach (died 829) and grandfather Ruaidrí mac Fáeláin (died 785) were Kings of Leinster.
The succession of kings in Leinster is difficult to follow in his time.
The king lists in the "Book of Leinster" have him listed after two kings who died later than he (869 and 885) and the next king is Túathal mac Máele-Brigte who died in 854.
Another previous king was Ruarc mac Brain who died in 862.
The king list gives Muirecán a reign of one year which would coincide to 862-863.
Francis John Byrne suggests that the root of this apparent confusion lay in the fact that the Uí Dúnlainge kings exercised little real authority due to the aggressions of their western neighbour Cerball mac Dúnlainge (died 888), King of Osraige.
Cerball, while unable to install himself as king of Leinster, was able to prevent any rival king exercising real power there.
In his obit in the annals in 863 it states that he was killed by the Norsemen.
He is only accorded the title of King of Naas and Airthir Liphi.
His sons Domnall mac Muirecáin (died 884) and Cerball mac Muirecáin (died 904) were also kings of Leinster, while his son Máel Mórda mac Muirecáin (died 917) was king of Airthir Liphi.
Cerball mac Muirecáin
Cerball mac Muirecáin (died 909) was king of Leinster.
He was the son of Muirecán mac Diarmata and a member of the Uí Fáeláin, the descendants of Fáelán mac Murchado (died 738), of one of three septs of the Uí Dúnlainge of modern County Kildare in Ireland.
Cerball succeeded his distant cousin Muiredach mac Brain of the Uí Dúnchada sept as king of Leinster on Muiredach's death in 885.
Unlike Muiredach, who was lay abbot of Kildare as well as king, Cerball appears to have been king only as one Lergus son of Cruinnén, bishop of Kildare, was killed in the battle of the Pilgrim, fought by Flann Sinna, the High King of Ireland, against the Vikings of Dublin in 888.
That same year, the neighbouring king of Osraige Cerball mac Dúnlainge, who had repeatedly attacked Leinster over the previous decades in an attempt to make it subject to him, died.
The Annals of Ulster contain relatively few reports of Cerball's reign.
In 902 they state that he, together with Máel Finnia mac Flannacain of Brega lead an expedition to Dublin which drove the "foreigners", the Vikings and Norse-Gaels, from Ireland.
He fought alongside Flann (whose daughter Gormflaith ingen Flann Sinna he married), against the men of Munster at the Battle of Bellaghmoon (near Castledermot) where Cormac mac Cuilennáin, King of Munster and Bishop of Cashel, was killed.
Cerball died in 909, when the Annals of Ulster report:
Cerball son of Muirecán, an excellent king of the Laigin, died of a sickness.
Given the biases of the Annals of Ulster, it is understood that Cerball had been a reliable ally of his father-in-law Flann Sinna.
He was memoralised in a poem by his poet, Dallán mac Móre.
After Cerball's death, Gormflaith married Niall Glúndub.
Later traditions had it that she had wished to marry Cormac mac Cuilennáin, but that he had taken vows of celibacy, so for reasons of state she was married to the brutal Cerball, before finding a short period of happiness with Niall, who died in battle in 917.
These tales appear to be largely poetic invention.
Cerball was succeeded by his distant cousin Augaire mac Ailella of the Uí Muiredaig sept.
He himself had no recorded issue.
