Eoghanachta of Munster - 30A.
909 AD. The Gaelic Milesian Irian Loigis Septs who had their territory in Co. Laois in the mid - north - west of Southern Leinster were therefore not of the Heremonian Ui Laoghaire Ui Lughaidh Cu Corb Septs there, but despite this some of the Families there were originally connected there through 84.Cu Corb, and because of this they had continued to hold out against the Gaelic Milesian Munster Septs on their behalf, and were their most favoured vassals, which was a similar arrangement as that which the Heberian Cianachta Gailenga Septs and the Cianachta Septs, themselves who were descended from 85.Cian, (a brother to 85.Eoghan Mor ancestor of the Heberian Eoghanachta and 85.Cormac Cass ancestor of the Heberian Dal gCais Septs were to have with the Heremonian Dal Cuinn Ui Niaill Septs. The Gaelic Milesian Irian Loigis Septs were to have 7 independent connected Septs of their own, with one of these being the Heremonian Ui Laoghaire Ui Lughaidh Cu Corb Ui Enechglais Sept who had their territory near Arklow, who were descended originally from 91.Bressal Enechglas, one of the 9 sons of *90.Cathair Mor who had been the Gaelic Milesian Heremonian Ui Laoghaire Ui Lughaidh 109th King of Tara / Ireland, while another was the Heremonian Ui Laoghaire Ui Lughaidh Cu Corb Siol mBrain Sept who had their territory in the south west of Co. Wexford in the south - east of Southern Leinster. There was also the Benntraige Sept who were another Fortuath Sept who were at Bantry in the Munster Province.
The continual Viking interference in Ireland was to bring about great upheavals in the Celtic aristocratic warrior order and during the 10th Century AD the Heremonian Ui Laoghaire Ui Connla Kings of Ossory / Co. Kilkenny were to continue to try and gain greater authority over the Kingship of Leinster for themselves until eventually 114.Donogh mac Gilla Patraic (later Normanized to Fitz Patrick) was to finally displace the Heremonian Ui Laoghaire Ui Lughaidh Cu Corb Ui Dunlainge Sept and be recognized in his own right also as the Heremonian King of Leinster. During the 11th Century AD the previous dominant Heremonian Ui Laoghaire Ui Lughaidh Cu Corb Ui Dunlainge Tuath / family region would be well and truly feeling the crunch of being weakened considerably by the Centuries of battle against their kinsmen the Heremonian Ui Cobhthaigh Dal Cuinn Ui Niaill Septs and the Norse Vikings from out of Dublin until they were finally to be defeated by the Heremonian Ui Laoghaire Ui Connla Ossory Sept, whose insignificant kingdom actually created a buffer zone between the Munster Province and the Leinster Province in Mogha's Half. The Heremonian Ui Laoghaire Ui Connla kingdom of Ossory situated in the south - west of Southern Leinster was to constantly escape the over lordship of the Heberian Septs in Munster as they endeavoured to become the Kings of Leinster in their own right, while their close kinsmen the more dominant Heremonian Ui Laoghaire Ui Lughaidh Cu Corb Septs in Southern Leinster were always under attack, either from the Heremonian Dal Cuinn Ui Niaill Septs, the Heberian Eoghanachta Septs, the Heberian Dal gCais Septs, the various Irish Septs from the Ulster Province, and the Vikings, but just like the Gaelic Milesian Irian Ulaidh in eastern Ulster Province they were to continue to be more racially united.
910 AD. The Heberian Dal gCais Prince, 103.Lorcan aka Finghin who had been previously advised by 102.Cormac mac Cuilennain the Heberian Eoghanacht 30th King of Cashel / Munster of the right of the Heberian Dal gCais Sept to the Kingship of Munster had by now become the Heberian Ui Bloid Ui Turlough King of Tuath Muman / Thomond / Northern Munster although based in Co. Clare / Southern Connacht, that also took in their territory in the north of Co. Tipperary, and the north of Co. Limerick and Co. Waterford to the east coast, and he was to produce 5 sons, 104.Kennedy / Ceann Eidigh who would be the direct male line ancestor of the O Brians / O Briens and the O Kennedys. 104.Cosgach who was to be the direct male line ancestor of the O Hogan Families of Munster 104.Longargan the direct male line ancestor of the O Lonergans, 104.Congal, and 104.Brann Fionn whose descendants were to have their territory in Co. Wexford in the south - east of Southern Leinster were some of his descendants also anglicized to O Breen. He was therefore to be an uncle of 105.Brian Boru - of the Tributes who was to be the 175th High King of Ireland a son of 104.Kennedy, and because of this some of his descendants were also to change their names to O Brien. 104.Kennedy would now push for the Heberian Dal gCais Sept to receive recognition of their right to the Heberian Kingship of Cashel / Munster.
914 AD. The second great wave of Viking raids began in Ireland as a massive fleet arrived into Co. Waterford in the south - east of the Munster Province, and from now on their aggressive onslaught continued on with their forces raiding further inland and Munster and Southern Leinster / Mogha's Half was once again to take the brunt of their attacks, which was to only further weaken the aristocrat warrior Heberian Eoghanacht Septs.
915 AD. Another Viking fleet arrived into Co. Waterford in the south - east of the Munster Province.
917 AD. *100.Niall mac Aeda Glun Dubh - of the Black Knee was now the Gaelic Milesian Heremonian Ui Cobhthaigh Dal Cuinn "northern" Ui Niaill Cenel nEogain 170th King of Ireland who led both of the Heremonian Dal Cuinn Ui Niaill Septs in the north and the south to assist the Heberian Eoghanachta in the Munster Province against the relentless ongoing attacks of the Vikings, and also laid siege to their stronghold in Waterford in Co. Waterford, but by now the Viking settlements in Munster had grown too numerous. *100.Niall Glun Dubh - of the Black Knee was naturally also dependent on the assistance of the Heremonian Septs in Southern Leinster, but 108.Augaire the Heremonian Ui Laoghaire Ui Lughaidh Cu Corb Ui Dunlainge Ui Muiredaig 35th King of Leinster was to be defeated in a battle against the Vikings near St. Mullins in Co. Carlow in Southern Leinster where there was great slaughter, which then allowed Sitric the Viking King to re - occupy Dublin also, once again, and establish a Viking kingdom there to be then able to carry out raids into the north and the south of Ireland.
919 AD The Vikings were to defeat the combined Irish forces led by *100.Niall Glun Dubh - of the Black Knee the Gaelic Milesian Heremonian Ui Cobhthaigh Dal Cuinn "northern" Ui Niaill Cenel nEogain 170th King of Ireland who was also killed in the conflict becoming the direct aristocrsatic warrior male line ancestor of all of the O Niaill / O Neill and Mac Laughlin Families from the Ulster Province.
The Vikings now also settled once again into the region that is now the City of Cork in Co, Cork in Southern Munster.
