1021 - 1030 AD 

1021 AD 107.Donnell / Domhnall O Niall, the son of 106.Aedh O Niall of Craeb Tulcha in the Ulster Province, who was now the heir apparent / Tanaiste to the Heremonian Cenel nEogain kingdom in Ulster Province carried out an "expedition' into the territory of the Heremonian Dall Cuinn Colla Da Crioch Ui Dorrthainn Sept in Magh Itechta were the Lethderg was slain and the Septs from the kingdom of Orghialla (Oriel) the Colla Da Crioch Ui Meith, the Colla Mend Mughdhorna, the Saithne, and those from Fearnmhagh were all to be involved in this conflict. The Colla Da Crioch Ui Dorrthainn Sept came and placed their forces behind him and also in front of him, while the Colla Da Crioch Siol Daim Argait Ui Ceileachan Sept, the Ui Lorcain Sept, along with the Colla Da Crioch Airthir Ui Bressail Macha Sept and the Colla Da Crioch Airthir Ui Niallain Sept were also out in front of him at Aenach Macha, where they all had him surrounded. Despite these combined forces of the Heremonian Dal Cuinn Colla Da Crioch Septs 107.Donnell O Niall's men were still to be victorious, although he only had a twelve score force of warriors, compared with all of their "combined" Colla Da Crioch forces, and many were to be slain there in this offensive to be come known as the "Battle of Aenach Macha," including 106.Aed O Niall of Craeb Tulcha himself, and Donnell O Murrough / Domhnall Ua Murchada from the Colla Da Crioch Siol Daim Argait Ui Cremthainn Clann Lugainn.  

1022 AD The Irish Septs in the Ulster Province decided to take on the Teutonic Scandinavian Vikings at sea again.

      *107.Malachy 11 / Mael Sechnaill the Heremonian Dal Cuinn "southern" Ui Niaill Clann Cholmain 40th King of Meath and 174th King of Ireland, "died" this year at Cell / Cro Inis on the island in Loch Annin in Co. Westmeath in the south - west of Northern Leinster and was interred on Cormorant Island in his Sept's territory in Co. Westmeath, and the ancient fortress of Tara in Co. Meath was now to be "totally" abandoned altogether as the main seat of the Kings of Ireland. The term of Ard Ri (High King of Ireland) would not now be used for the next 66 years, due to the new rule of "Survival of the Fittest" still prevailing owing to the Viking disruptions, and the various independent individuals who were from now on to be "contesting" for the top position. *107.Malachy 11 was to be the "last" from the Clann Cholmain Sept to occupy the overall position of King of Ireland, and his Mael Sechlainn / Melaghlin descendants in the "southern" kingdom of Meath / Midhe from now on became known as the O Melaghlins / Ui Mael Sechnaill, and were still later on to be further known as the Mac Laughlins. Up to *107.Malachy 11's "demise" there had been 48 Christian Kings of Ireland.

      Sitric, the Viking son of Imhar, the Chief of Port Lairge, was slain by 110.Donough mac Gilla Patrick / Patraic  (Descended from a son of a Devotee of St. Patrick.) the Heremonian Ui Laoghaire Ui Connla King of Ossory who had his territory in Co. Kilkenny in the south - west of Southern Leinster, and it would be 110.Donough mac Gilla Patricks' descendants later on, after the Anglo - Norman English Invasion in 1167 AD, who were to "Normanize" their name to Fitz Patrick.

     At this time, Ranald was to be the Teutonic Scandinavain Viking King of Waterford in Co. Waterford in the south - east of the Munster Province until 1031 AD who would later be slain in 1035 AD.

1023 AD With the "Irish Brehon Law" still in bedlam the High Kingship of Ireland was now well and truly up for "grabs," *106.Donough / Donnchad mac Brian the "younger" Heberian Dal gCais, (son of *105.Brian Boru and 110.Gormflath), allied himself with the Heberian Cianachta Septs from the kingdom of Ely O Carroll that was situated nearby on the border of Co. Tipperary in the south of Co. Offaly in the mid - north - west of Southern Leinster, and their "combined" forces were to go up against 106.Teague / Tadhg, his "older" half - brother, the son of *105.Brian Boru and Eachraidh, who was to be "slain" in the conflict, and then with no real opposition *106.Donough mac Brian would become the Heberian Dal gCais 42nd King of Cashel / Munster. Despite this finghal / kin slaying, in the future it would be 106.Teague mac Brian's son, *107.Turlough O Brian who would become the Heberian Dal gCais 43rd King of Cashel / Munster after him and also the 178th King of Ireland, and it would then be his "direct male" line that would carry their Heberian Dal gCais Ui Bloid Ui Turlough Ui mBriain male line forward from *105.Brian Boru as the Heberian Dal gCais Kings of Cashel / Munster and Kings of Ireland. Their aristocratic warrior control over the Dal gCais Septs would also come to an "end" eventually with his descendant, 110.Donnell Mor O Brian in 1194 AD well after the Anglo - Norman English Invasion, due to 110.Donnell Mor O Brian's persistence in persuing his own "personal agendas" instead of the overall good of the Dal gCais Sept and Ireland. In the meantime, *106.Donough mac Brian was to also "assume" the greater  position of the 176th Kingship of Ireland - with opposition until he was to eventually be "banished" by *110.Diarmait mac Mael na mBo the Heremonian Cu Corb Ui Cheinnselaig 61st King of Leinster who would then become the "unofficial" 177th King of Ireland during that later period. The tenets of the "Irish Brehon Law" were by now under "great strain," as was the overall "Kingship of Ireland" and those Irish Septs who were individually "stronger" from now on would take the "opportunity" to improve their aristocratic  warrior "position" in the overall scheme of things.

     Ainbith O Casey the Heberian Cianachta King of Saithne in Bregia in Co. Meath in Northern Leinster was slain this year.  

1024 AD 107.Donnell / Domhnall O Niall, the son of 106.Aed O Niall of Craeb Tulcha, was now the heir apparent / Tanaiste to the Heremonian Dal Cuinn "northern" Ui Niaill Cenel nEogain kingdom of Aileach in the north of the Ulster Province and to improve his position further he was to carry out an "expedition" into the "southern" territories of the Heremonian Dal Cuinn Colla Da Crioch Ui Meith Sept and the Colla Da Crioch Ui Dorrthainn Sept in Midhe / Meath in Northern Leinster to try and express his future chances of overall authority there, but unfortunately for him he was to be "slain" in the ensuing conflict by Gillamura, the son of Ocan.  

1025 AD 107.Flaherty / Flaithbertach an Trostain O Niall - of the Pilgrim's Staff who was the actual Heremonian Dal Cuinn "northern" Ui Niaill Cenel nEogain 40th King of Aileach in the north of the Ulster Province also carried out a "southern" expedition into the "southern" kingdom of Brega in the south - east of Midhe / Meath in Northern Leinster to expand his own personal authority further there also, and while he was there he was able to "buy back" the Gaelic hostages that were being held there by the Teutonic Vikings.

1026 AD 107.Flaherty / Flaithbertach an Trostain O Niall  - of te Pilgram's Staff the Heremonian Dal Cuinn "northern" Ui Niaill Cenel nEogain 40th King of Aileach carried out another "southern" expedition into Midhe / Meath in Northern Leinster to expand his authority there even further, and this time he also gained their "pledges," and besieged Inish Mochta while he was also there.

1026 AD 110.Donough mac Gilla Patrick / Donnchad mheic Gilla Patraic the Heremonian Ui Laoghaire Ui Connla King of Ossory in the south - west of Southern Leinster, was by now also asserting his own new found overall authority in Southern Leinster and he besieged the territory nearby of 112.Donough / Donnchad the Heremonian Ui Laoghaire Cu Corb Ui Dunlainge Ui Muireadhaigh 49th King of Leinster, where he gained a great deal of booty, and while there to further express his growing capacity to do so, he also besieged the territory of their Cu Corb Ui Dunlainge kinsmen, the Ui Cheinnselaig Sept who were by this period in time also "beginning" to re - emerge as a "threat" also once again to the overall Kingship of Southern Leinster.

    109.Roen O Melaghlin, the son of 108.Murtough / Muirchertach, the son of *107.Malachy 11 / Mael Sechnaill the previous *174th King of Ireland from the Heremonian Dal Cuinn "southern" Ui Niaill Clann Cholmain Sept, was now the heir apparent / Tanaiste and to show his authority there also he "defeated" the Irish Septs in the kingdom of Bregia in the east of Co. Meath in Northern Leinster and their present allies the Teutonic Vikings from out of Dublin who were led by Sitric, the son of Olaf / Auluf Cuaran, who was still the Viking King of the Danes in Dublin and also Donough / Donnchadh, the son of Donn, the Dal Cuinn "southern" Ui Niaill Chief of Bregia in Co. Meath. Although the Viking Danes and the Irish Septs of Bregia had been "defeated," and many of them had been slain along with Donough the Chief of Bregia, and Gillausalle, the son of Gilla Caemhghin the Chief of the Dal Cuinn Ui Briuin Sept they were still able to regroup and turn back and attack 109.Roen O Melaghlin and his Clann Cholmain forces "again" and "defeat" them, and he was also "slain" along with many others from the Heremonian "southern" Ui Niaill Siol nAedo Slaine and the Clann Cholmain Septs there in Meath, which had a further great "detrimental effect" on the overall position of the once "powerful" Heremonian Dal Cuinn "southern" Ui Niaill.

     Dungal O Donoghue the Heberian Eoghanacht King of Cashel who had fought along side of *105.Brian Boru in the "Battle of Clontarf" against the Vikings and their Southern Leinster allies, "died" this year.   

1027 AD "Safe passage" was promised this year by the Emperor Conrad for any of the Catholic clergy to go abroad, and "pilgrimages" became much safer from now on, and travel would broaden their horizons to bring about further religious "reform" in Ireland.

       With the "Irish Brehon Law" in turmoil due to the previous Teutonic Viking disruptions it was by now well and truly down to the "Survival of the Fittest," as any of the Irish Septs who were in with a chance, continued to struggle for overall control in their "respective" territories in Ireland with *106.Donough, (the son of *105.Brian Boru and 110.Gormlaith), now the Heberian Dal gCais 42nd King of Northern Munster / Thomond after being involved in the early "demise" of his older half - brother, 106.Teague, and this year he had intended to exert even greater influence in Mogha's Half over the Heremonian Ui Laoghaire Ui Connla kingdom of Ossory in Co. Kilkenny in the south - west of Southern Leinster, now under the growing strength and outstanding leadership of 110.Donough mac Gilla Patrick, but he was "defeated."    

1028 AD Sitric Silkbeard, who was the half - Viking King of Dublin, and the older son of 110.Gormlaith and Olaf Cuaran the previous Danish Viking King of Dublin, was now on friendly terms with the nearby Heremonian Dal Cuinn "southern" Ui Niaill Siol nAedo Slaine King of Brega in the east of Co. Meath in the Northern Leinster and they both went off together to visit Rome, and Sitric Silkbeard also gave over a site for a "new church" of the Holy Trinity in Dublin.

      *106.Donough / Donnchad, (The son of *105.Brian Boru and 110.Gormlaith), the Heberian Dalcassian 42nd King of Northern Munster / Thomond was now to become the "undisputed" Heberian Dal gCais 42nd King of Cashel / Munster until 1064 AD and he gathered together all those who had served his father previously, to try and further assert his own personal overall authority in Ireland and then carried out a "kingly" circuit in Ireland going up through Meath / Midhe in the south of Northern Leinster, and then down to Dublin into the east of Southern Leinster, then back down through the kingdom of Ossory in Co. Kilkenny were he took many hostages and subdued all who would not at first give him official recognition. This now meant that he had regained "sovereignty" over all of Mogha's Half / Leath Mogha / Southern Ireland / Munster Province and Southern Leinster, and boyed by his immediate success, to further consolidate his position, he then laid siege to and submitted, many of the other Irish Septs, gaining hostages from the Connacht Province, from Southern Leinster, and also from Meath / Midhe in Northern Leinster. He now also personally called himself the 176th King of Ireland, but despite all of his immediate success, he was still under "siege" from the growing fortunes of 112.Donough mac Gilla Patrick in the nearby kingdom of Ossory in Southern Leinster, and the increasing revival of the Heberian Eoghanacht Septs at Cashel in Co. Tipperary in the north - east of the Munster Province. Many of the other Irish Septs in Southern Leinster and in the Connacht Province were also still giving him trouble, and he was also soon to be confronted by his kinsman, *107.Turlough O Brian, the son of his older deceased half - brother, 106.Teague, whose previous demise he had been heavily involved in.

      Art O Donoghue, the son of O Donoghue of Cashel in Co. Tipperary, who was the Erenagh of Mungret in Co. Limerick in the Munster Province, died.

       Kenneth / Cinaeth Mac Eniry the Heberian Eoghanacht Ui Fidgeinti Ui Cairbre Aebda King of Connello in Co. Limerick in the north - west of the Munster Province was slain this year in battle.  

1030 - 1033 AD 107.Flaherty / Flaithbertach an Trostain O Niall - of the Pilgrim's Staff was to be the Heremonian Dal Cuinn "northern" Ui Niaill Cenel nEogain 40th King of Aileach in the Ulster Province, who was a son of 106.Murtough / Muirchertach O Niall, a son of *102.Donnell Ard Macha O Niall the previous 173rd King of Ireland and he decided to also go on a pilgrimage to Rome, from where he was to pick up his epithet, and his son, 108.Aedh Athlaman O Niall - the Handy took his place becoming the 41^st King of Aileach in Tyrone / Tir Eogain (The Land of 91.Eogan) who was the heir - apparent / Tanaiste, who would soon die and leave behind a son, 109.Donnell / Domhnall an Trogdam O Niall - the Young Ox who was to become the future Cenel nEogain King of Ulster Province, although - in opposition. He in turn would then become the direct "male line" ancestor of *116.Brian Catha Duinn O Niall who would lay claim to be the "last" from the Dal Cuinn "northern" Ui Niaill Sept to be the 184th High King of Ireland who would be slain in battle in 1258, He was also to be the "ancestor" in the future of the appointed English Earls of Tyrone, and the O Neills of Clannaboy / Clann na Bhuidhe whose kingdom was to be in the north - east of Ulster Province. Another of his descendants in more modern times was to be Terence O Neill who would be the nominated Prime Minister of the 6  Counties of Ulster Province, under the British Imperial Empire's "artificial partition" by threatened force of arms of the 6 of the 9 Counties of Ulster Province for egotistic, ethnic and especially "sectarian political" reasons in the future, that would bring about continuing "misery, death, and endless suffering" to all who were to be still existing there in those 6 Counties.

   Rory O Cannon / Ua Canannain the Heremonian Dal Cuinn "northern" Ui Niaill Cenel Conaill King of Tyrconnell / Tir Conaill who had his territory in Co. Donegal in the north - west of the Ulster Province was slain by 108.Aed Athlaman O Niall - the Handy, the acting "northern" Ui Niaill Cenel nEogain 41st King of Aileach, in a dispute over who now had the overall authority in Ulster Province.

      Reginald the Danish Viking Chief in Waterford in Co. Waterford in the south - east of the Munster Province built the first Catholic "church" there.

1030 AD - 1073 AD Another of the O Melaghlins / Mael Sechnaill who was now the Heremonian Dal Cuinn "southern" Ui Niaill Clann Cholmain King of Meath / Midhe, who had his royal residence at Cro - Innis, defeated Cu Caille the Heremonian Cu Corb Fir Thulach King, who was a son of Dubh Laidhe, and he then also took over the territory there in Carrick in Co. Westmeath in the south - west of Northern Leinster and gave it to his Queen, as this particular territory had been held onto until now by the Heremonian Cu Corb Ui Cheinnselaig Fir Thulach Mide Sept. Prior to this in 598 AD 99.Brandub the Heremonian Cu Corb Ui Cheinnselaig 7th King of Leinster had been able to defeat *92.Aedh mac Ainmerech who was then the Heremonian Dal Cuinn "northern" Ui Niaill Cenel Conaill 140th King of Ireland at Dun Bolg and this defeat had then stopped any further Dal Cuinn Ui Niaill Sept's expansion in that region. 99.Brandub's direct Heremonian Cu Corb Ui Cheinnselaig descendants the Fir Thulach Mide Sept had then continued on to rule in their kingdom there still, but only under the auspices of the Dal Cuinn "southern" Ui Niaill Clann Cholmain Sept, until Conor's son’s daughter had married Conor O Melaghlin / Mael Sechnaill.
