1081 AD Mac Eniry / Mac Angheiree the Heberian Eoghanacht Ui Fidgeinti Ui Cairbre Aebda King of Connello / Conaile was killed at the Battle of Fermoy near Thurles this year.

1084 AD *107.Turlogh O Brian the Heberian Dal gCais 178th King of Ireland was not getting any younger and opportunities to gain the future overall Kingship of Ireland was now in a state of flux due to the long running disruptions to the Irish Brehon Law, created by the previous ongoing Teutonic Viking attacks that had by now occurred all over Ireland for nearly 300 years and on the off a future change in the overall leadership in Ireland, 109.Dunslieve mac Hoey / Donnsliebe mac hEochada the Dal Fiatach 56th King of Ulaid in the north - east of the Ulster Province this year gave gifts to a possible up and coming contender in 112.Donogh O Rourke /  Donnchad Ua Ruairc the Dal Cuinn Ui Briuin Breifne King of West Breifne who had his kingdom in Co. Leitrim in the north of the Connacht Province. He was hoping to revive the Fifth of Ulster so that he  could be seen as a current ally and rival in the Ulster Province against the interests of *109.Donnell Mac Loughlin  / Domhnall Mac Lochlainn who was now the the Dal Cuinn "northern" Ui Niaill Cenel nEogain 51st King of Aileach who was another of the contenders for the overall Kingship of Ireland. *109.Donnell Mac Loughlin was to deal with the ambitions of 109.Dunslieve mac Hoey personally, while *107.Turlogh O Brian the present 178th King of Ireland crushed any future intentions that 109.Donough O Rourke might also have at the Battle of Moin Cruinneoice near Leixlip / Leim an Bhradain (The Salmon's Leap) in Co. Kildare in Central Southern Leinster. *107.Turlogh O Brian was at this time trying to maintain his own overall authority throughout Ireland, and to this end he left his main territory in the the Munster Province and carried out an expedition especially  into the Dal Cuinn "southern" Ui Niaill kingdom of Meath / Midhe in the south of Northern Leinster and then also throughout the Leinster Province generally. When *107.Turlogh O Brian was away on his expeditionj, 113.Rory na Saide Buide O Connor who was now the Dal Cuinn Ui Briuin Ui Conchobair 51st King of Connacht decided that this would be a good time also to express his future intentions, and with his Dal Cuinn Ui Briuin Septs he laid siege to *107.Turlogh O Brian's personal territory in Co. Clare around Tuamgraney, Moyno and Killaloe, in the north - west of the Munster Province, which was the region to the south of the Connacht Province, that was geographically in reality a part of it.

       108.Kennedy O Brian / Cenn Etig Ua Briain the Dalcassian King of Tulcha Oc, died, this year, who was a son of 107.Lorcan O Brian who had died in 1078 AD, the son of *106.Donogh mac Brian the previous 42nd King of Cashel / Munster, and 176th King of Ireland - with opposition, who had been the son of *105.Brian Boru - of the Tributes the previous 175th High King of Ireland and 110.Gormlaith. 108.Kennedy O Brian had also been a brother to 108.Conor O Brian the previous King of Tulcha Oc who hado died in 1078 AD the same year as his father. The recent demise of 108.Kennedy O Brian was to bring to an end their Ui Turlogh Ui mBriain male line descending from *106.Donogh mac Brian altogether to the Munster Kingship and the Kingship of Ireland as from now on it would only be the direct male line emanating from *106.Donogh O Brian's older half - brother, 106.Teague O Brian, whose death he had been personally implicated in, that would continue on the O Brian Ui Turlogh Ui mBriain Kingship line in Thomond / Northern Munster and Ireland.

     112.Donogh O Rourke the Dal Cuinn Ui Briuin Breifne King of West Breifne who had his territory and kingdom in Co. Leitrim in the north of the Connacht Province still believed that he was in with a show towards the Kingship of Ireland also, and this year in an attempt to begin his campaign he laid siege to and burnt the region of Kilkenny in the kingdom of Ossory in Co. Kilkenny in the south - west of Southern Leinster, that was the Heremonian Ui Connla fortress of 112.Donnell mac Gilla Patrick / Domhnall  mac Giolla Patraic (Fitz Patrick) the King of Ossory.   

1086 AD Summer: *107.Turlogh O Brian the Heberian Dalcassian 43rd King of Cashel / Munster and the 178th King of Ireland, died at 77 years of age, whose father had been 106.Teague / Tadhg mac Brian who had predeceased him way back in 1023 AD, as the oldest surviving son of *105.Brian Boru the 175th High King of Ireland, and a half - paternal brother to *106.Donogh O Brian the previous 42nd King of Cashel / Munster and 176th King of Ireland. *107.Turlogh O Brian's son, *108.Murtogh / Muirchertach Mor - the Greater O Brian became the new Dal gCais King of Northern Munster / Thomond when he was crowned at Magh Adhair in Clooney - Quin by the Mac Namaras. He would later also become the 44th King of Cashel / Munster, and eventually the last Dalcassian 180th King of Ireland and die in 1119 AD and he immediately decided to begin his campaign to try and regain the Kingship of Ireland for the Dal gCais Ui mBriain Sept by first exerting his overall authority over the territory in Southern Leinster in Mogha's Half and then moved on to the Connacht Province to the north west of Co. Clare, still under the control of 113.Rory na Saide Buide O Connor the Dal Cuinn Ui Briuin 51st King of Connacht who not only defeated him, but also took him prisoner.

      113.Rory na Saide Buide O Connor then allied his Heremonian Dal Cuinn Ui Briuin forces with his Heremonian Dal Cuinn "northern" Ui Niaill Cenel nEogain kinsman, *109.Donnell O Loughlin / Ua Lochlainn the 51st King of Aileach in the Ulster Province, the son of 108.Ardgar / Ardgal O Loughlin the previous 44th King of Aileach. in the north of Ulster, who had by now become the Heremonian 179th King of Ireland until 1119 AD and then outright until 1121 AD. To show *108.Murrogh Mor O Brian who was now really in control in Ireland their combined forces besieged his territory in the east of Co. Clare in Northern Munster as far south as Limerick in Co. Limerick and also ransacked the Heberian Dal gCais Ui mBriain fortress at Kincora in the north - east of Co. Clare where they captured many of the Dalcassian Princes and their Danish / Dubh Gall Viking allies. After putting him in his place they eventually released *108.Murtogh Mor O Brian who was still the King of Northern Munster / Thomond, but he was as determined as ever to continue to try and also regain the Heberian Kingship of Cashel / Munster as he had not lost any of his original driving ambition to also eventually become the Heberian Dal gCais King of Ireland. To this end he then laid siege to 113.Rory na Saide Buide O Connor again in his Sept's territory to the north of Thomond in the Connacht Province and also plundered the north of Co. Tipperary in the north - east of the Munster Province where it adjoined Mogha's Half in Southern Leinster. He then went further to the north to the Ulster Province where he attacked the Summer Fortress / Grianan of Aileach belonging to the Dal Cuinn "northern" Ui Niaill Cenel nEogain Septs who were now under the leadership of *109.Donnell Mac Loughlin the Heremonian 179th King of Ireland in the north - east of Co. Donegal. Because of this particular effort *108.Murtogh O Brian now gained a lot of support throughout Ireland toward gaining the overall Kingship of Ireland eventually for himself, and he then set out on a further victorious circuit of his own to assert that he now had the overall Heberian authority in Ireland once again.
