for the next 30
years
in his own right and be able to gain an alliance with the

Waterford in
Co. Waterford
along the coast in the south - east of
Munster,

Wexford and
Dublin

Southern Leinster,
while eventually becoming
the overall ruler of

Heremonian
Dal Cuinn

Aodh

Skellig
Michael monastery, situated off the coast of Co. Cork
in Southern Munster, died this year.
1045 AD 107.Carthy / Carthach (the Loving One) who was a renowned aristocratic warrior and Heberian Eoghanacht Chaisil Prince / Tanaiste in the south of the Munster Province, who was a grandson of 105.Donogh / Donnchad the previous Eoghanacht 38th King of Cashel / Munster, was killed this year when the Heberian Dalcassian O Lonergan Sept burnt his residence while he was still in it, and he was to now become the direct male line ancestor of all of the Mac Carthys of Des Muma / Desmond / Southern Munster who were to be descended from his son. Laidir - the Strong mac Carthy became the Eoghanacht Prince / Tanaiste / heir apparent of Muskerry at Blarney in Co. Cork in Southern Munster, and due to their increasing importance the Mac Carthys were to also construct Balla Castle, which is the oldest inhabited Castle in Ireland today, at Carrig Aline in Co Cork, as their Sept was to now begin to gain great prominence there in Desmond / Southern Munster.
Casey / Cathasaigh O Corcoran the Heberian Cianacht Co - Arb of Glen Uissen in the Heremonian Ui Laoghaire Cu Corb Ui Bairrche / O Gorman territory in Co. Carlow in Southern Leinster, died this year.
1045 - 1061 AD AD Garvey / Gairbhedh O Casey was to be the Heberian Cianacht King of Breagh / Brega in the east of Co. Meath in Northern Leinster.
1046 AD108.Murtogh O Niall the Tanaiste / heir apparent from the Dal Cuinn "northern" Ui Niaill Cenel nEogain Sept who was one of the sons of 107.Flaherty / Flaithbertach an Trostain - of the Pilgrim’s Staff O Niall the previous 40th King of Aileach in the Ulster Province, laid siege with Aiteidh Ua hAiteidh the Gaelic Milesian Irian Ui Echach Ulaidh King from the north - east of the Ulster Province, to the Heremonian Dal Cuinn "southern" Ui Niaill Siol nAedo Slaine kingdom of Brega in Meath / Midhe in the south - east of Northern Leinster. Gairbhedh O Casey / Ua Cathasaigh the King of Brega overtook him at Cassan Linne while the tide was still up and 108.Murtogh O Niall and Aiteidh Ua hAiteidh the Irian Ui Echach Ulaidh King, along with many others were killed, as they were burnt to death in a house set on fire there in Uachtar Tire by Cu Uladh from the the Heremonian Dal Fiatach Sept, who was a son of Congalach, This particular death was t have great consequences as from now on for the next 104 years not one of the Heremonian Dal Cuinn "northern" Ui Niaill Cenel nEogain O Nialls was to be recorded in the Annals of Ulster.
1049 AD *106.Donogh mac Brian, (the son of *105.Brian Boru, and 110.Gormlaith), the Heberian Dal gCais 42nd King of Cashel / Munster was by now basically recognised as the 176th King of Ireland, although he still had plenty of opposition, and he decided to carry out a raid on the fortress of who he considered was now his strongest opponent, *110.Diarmait mac Mail na mBo the Heremonian Cu Corb Ui Cheinnselaig 51st King of Leinster who was set up at Ferns in Southern Leinster, as before he could really gain the title of overall Kingship of Ireland in his own right he needed to show that his authority still existed there in Mogha's Half, but undaunted 110.Diarmait Mail na mBo retaliated and besieged *106.Donogh mac Brian's personal territory in Co. Clare in the north - west of the Munster Province. Meanwhile, 112.Aed in Gai Bernaig O Connor the Heremonian Dal Cuinn Ui Briuin Ai 49th King of Connacht also took this opportunity to attack the southern part of Co. Clare to also show his continuing opposition to *106.Donogh mac Brian who in retaliation also then sent his son, 107.Murrogh - of the Short Shield O Brian with his Dalcassian warriors to the north - west to attack 112.Aed in Gai Bernaig O Connor. This forced *107.Turlogh O Brian, who was not only *106.Donogh mac Brian's son - in - law but also his nephew, to join forces with 112.Aed in Gai Bernaig O Connor, who had previously been his foster - father, and 15 of 107.Murrogh - of the Short Shield O Brian's Dal gCais Ui mBriain Chiefs and 400 of his Dalcassian aristocratic warriors were killed in the ensuing conflict. 112.Aed In Gai Bernaig O Connor then full of confidence decided to besiege and destroy the Dal gCais Ui Turlogh Ui mBriain strongholds at Kincora and Killaloe in Co. Clare, and after this *106.Donogh mac Brian was to also be defeated in Co. Tipperary in the north - east of the Munster Province. *106.Donogh mac Brian now finally decided that he had, had enough of the continual infighting and went off to Rome to do Penance for his previous escapades and he would eventually die there in 1074 AD,
All of the previous turmoil being carried out against *106.Donogh mac Brian made the overall position of *110.Diarmait mac Mail na mBo the Heremonian Cu Corb 51st King of Leinster, the son of 109.Donogh na Mael mBo, so dominant now that not only did he he set himself up on the Rock of Cashel in Co. Tipperary, but may have even reigned there as the unofficial 177th King of Ireland - although with opposition until he was to die in 1072 AD and he also installed *107.Turlogh O Brian, his foster - son, in as the new Heberian Dal gCais 43rd King of Northern Munster / Thomond to replace his uncle, *106.Donogh mac Brian. Over the years ahead *107.Turlogh O Brian, who was the son of *106.Donogh mac Brian's deceased older half - brother 106.Teague / Tadhg mac Brian, whose demise *106.Donough had been originally heavily involved in, would progress to become not only the 43rd King of Cashel / Munster, but also the 178th King of Ireland.
Turlogh O Casey from the Heberian Cianacht Sept of Saithne in Bregia in Co. Meath in Northern Leinster was killed this year.
