1071 - 1080 AD 

1072 AD *110.Diarmait mac Mail na mBo - of the Many Cattle the Heremonian Cu Corb Ui Cheinnselaig 51st King of Leinster and the 'un"unofficial" 177th King of Ireland - with opposition was slain in the "Battle of Odhbha" at Navan / An Uiamh (The Cave) in Co. Meath in the north - east of Northern Leinster, while trying to exert his overall authority further into the north against Conor O Melaghlin / Conchobar Ua Mael Sechnaill the Heremonian Dal Cuinn "southern" Ui Niaill Clann Cholmain King of Meath as his surrounding regional authority had been very "strong" while ruling for the previous 30 years as the Cu Corb 51st King of Leinster. After the previous death of 112.Murrough / Murchad the Heremonian Cu Corb Ui Dunlainge 50th King of Leinster in 1042 AD 110.Diarmait mac Mail na mBo had once again firmly re - established the fortunes of the Heremonian Cu Corb Ui Cheinnselaig / Kinsella dynasty and he had also caused his descendants once again to become "aware" that even the High Kingship of Ireland might now once again be available to the Cu Corb Heremonian Kings of Leinster, just as it had been before. This improvement in their fortunes may have been one of the main thoughts eventually driving the ambitions in the future of his great - grandson, 113.Diarmait mac Murrogh na Gall - of the Foreigners who would bring about the Anglo - Norman English Invasion in 1169 AD while persuing his own agenda in his interests only. 

     112.Donnell mac Murrough / Domhnall mac Murchada, was now to become the new Heremonian Cu Corb Ui Cheinnselaig 52nd King of Leinster until 1075 AD, who was one of the 3 sons of the previously deceased 111.Murrough / Murchad who had been the 51a King of Leinster that had died 2 years previously, and he in turn had been a son of *110.Diarmait mac Mail na mBo - of the Many Cattle the highly successful previous 51st King of Leinster and "unofficial" 177th King of Ireland - with opposition.

     110.Diamait mac Mail na mBo, was now gone from the scene in Southern Leinster in Mogha's Half, and his foster son,*107.Turlough O Brian, the son of 106.Teague / Tadhg (the son of *105.Brian Boru the previous 175th High King of Ireland and of Eachraidh), who was now the Heberian Dal gCais Ui mBriain 43rd King of Cashel / Munster decided to take this opportunity to try and expand his own personal authority there in Southern Leinster in Mogha's Half and he laid siege to the territory there to the east of the Munster Province and received hostages and gained submission from the Irish Septs throughout the region there, and was also able to "submit" the Vikings in the north - east in the Dublin region, which put him in line now for the overall Heberian Kingship of Ireland.

     Donough / Donnchad mheic Giolla Patraic (Fitz Patrick) the Heremonian Ui Laoghaire Ui Connla King of Ossory in Co Kilkenny in the south - west of Southern Leinster was also slain this year in battle against Conor O Melaghlin / Mac Loughlin / Conchobar Ua Mael Sechnaill the Heremonian Dal Cuinn "southern" Ui Niaill Clann Cholmain King of Meath / Midhe in the south - east of Northern Leinster whose once great Sept was now struggling to keep up to their previous position in the overall scheme of things in Mogha's Half.

      Lanfranc who had been appointed the Norman Catholic "Archbishop of Canterbury" in England by the Pope under William 1st the Conqueror now also claimed authority over the "Celtic Catholic Church" in Ireland as well.

1073 AD *107.Turlough O Brian the Heberian Dal gCais 43rd King of Cashel / Munster had by now re - gained the overall authority to the north of Mogha's Half also, in the O Melaghlin's Heremonian Dal Cuinn "southern" Ui Niaill kingdom of Meath / Midhe in Northern Leinster, so he then marched on the Connacht Province to the north - west of Northern Munster / Thomond and established his overall authority there also, and divided up the Leinster Province to suite his particular requirements and "weaken" his opposition there and this ensured greater "overall stability" in Mogha's Half, and to assist to further gain "overall" control in Ireland moving his chances now further towards the Heberian Kingship of Ireland.

   Maol Mor O Casey who at this time was the Heberian Cianacht King of Bregia in Co. Meath in Northern Leinster and his kinsman, Rourke / Ruarc O Casey were slain in a inter Sept dispute also over authority there.

1074 AD *107.Turlough O Brian the Heberian Dal gCais  Ui Bloid Ui Turlogh Ui mBriain 43rd King of Northern Munster became the 178th King of Ireland this year, and to strengthen his position further he installed his son, 108.Murtough O Brian / Muirchertach Ua Briain as the Heberian Dal gCais King of Dublin, which was to continue his chances of holding overall control there also against the interest of the Teutonic Vikings.

1075 AD *107.Turlough O Brian as the Heberian Dal gCais 178th King of Ireland began carrying out further "expeditions" into the north of Ireland to try and extend his real overall authority there also, but his warriors came up against "great opposition" in Co. Louth in the north - east of Northern Leinster and were defeated in battle there and this first loss caused him to turn to 113.Rory / Ruaidri na Saide Buide O Connor the Heremonian Dal Cuinn Ui Briuin Ui Conchobair 51st King of Connacht for assistance, which then gave 113.Rory na Saide Buide O Connor a much "better hand" also in the future scheme of things, remembering the tenets of the "Irish Brehon Law" was in freefall, but despite this *107.Turlough O Brian was now "officially"recognised as the 178th King of Ireland - although still with opposition in the far - north of Ireland.  

    Godfrey the Viking King of Dublin, "died" this year.

1076 AD *107.Turlough O Brian the Heberian Dal gCais 178th King of Ireland now decided to lay siege to the Connacht Province to ensure that his overall authority also there continued to remain intact, and as a result he finally gained submission from his former ally 113.Rory na Saide Buide O Connor the Heremonian Dal Cuinn Ui Briuin Ai Siol Muireadhaigh / Sil Murray Ui Conchobair 51st King of Connacht.

     The fortunes of the O Melaghlins / Mac Laughlins the previous Heremonian Dal Cuinn Clann Cholmain Kings of Ireland were continuing to "decline" and to add to this their leader Murrough O Melaghlin / Mac Laughlin / Murchad Ua Mael Sechnaill from the Heremonian Dal Cuinn "southern"" Ui Niaill Clan Cholmain Sept was slain this year in the "Round Tower" at Ceanannus Mor / Kells in Meath / Midhe in his territory in the south - east of Northern Leinster.  

1078 AD 107.Larkin / Lorcan O Brian, "died," who was one of the 2 sons of * 106.Donough mac Brian the previous Heberian Dal gCais 42nd King of Cashel / Munster and 176th King of Ireland who had been the (son of *105.Brian Boru and 110.Gormlaith), who had died in 1074 AD, and 108.Conor / Conchobar O Brian and 108.Kennedy / Cenn Etig O Brian who were 2 of his sons would go on to become Kings of Tulcha Oc, which on their demise would also bring to an "end" their direct male line to the Heberian Kingships of Northern Munster / Thomond, Cashel / Munster and of Ireland altogether. 108.Conor O Brian who was the present King of Tulcha Oc, would be the first to die this year.

    Conor O Donoghue the Heberian Eoghanacht Prince / Tanaiste of Cashel, "died" this year, and with his death came the gradual demise also of this once great Gaelic Milesian Sept who had their territory in Co. Tipperary in the Munster Province. 

1079 AD *107.Turlough O Brian who was now the Heberian Dalcassian 178th King of Ireland "expelled" his previous ally 113.Rory na Saide Buide O Connor the Heremonian Dal Cuinn Ui Briuin Ai Siol Muireadhaigh Ui Conchobair 51st King of Connacht, but despite this powerful action he was still "not able" to gain total overall submission in the "north" of Ireland, although some of the "northern" Irish Kings did eventually come down personally to the south and "submit " to him and he also received a "further submission" from the O Melaghlin / Ua Mael Sechnaill who was now the Heremonian Dal Cuinn "southern" Ui Niaill Clann Cholmain King of Meath in Northern Leinster while the Abbot of Armagh was in attendance with the Staff of Jesus.

      Armagh in Co. Armagh in the Ulster Province was still holding open "one third" of their class rooms for students who were from Albion / Briton.

      Aed Mac Criffan / Mheic Crimthainn the Abbot of Terryglass / Tir Dha Ghlas (The Land of Two Streams) in Co. Tipperary in the north - east of the Munster Province compiled the Book of Leinster during this period.

1080 AD *107.Turlough O Brian the Heberian Dalcassian 178th King of Ireland besieged and sacked  the Viking stronghold in Dublin in Co. Dublin the north - east of Southern Leinster to ensure his overall authority still existed there in that very important and "troublesome" part of Mogha's Half.  

     The Heberian Eoghanacht Moriartys / Ui Muirchertaigh who had their territory near Killorglin in Co. Kerry in the south - west of the Munster Province were now "ousted" from there by the ever growing authority of their kinsmen, the Heberian Eoghanacht Chaisil Mac Carthys, who themselves were to be "ousted" from there later on in 1170 AD by the Fitz Geralds  the "Cambro - Norman Barons" after the Anglo - Norman English Invasion to come in 1167 AD.

    Eochy O Lynch the Heberian Dal gCais Ui Bloid King of Owney on the border of Co. Tipperary and Co. Limerick, "died."
