841 - 850 AD 

841 100.Felim mac Crimthainn the Heberian Eoghanacht Chaisil 23rd King of Cashel / Munster led his forces to Carman intending to proclaim his overlordship and celebrate an Oenach / Assembly, but *101.Niall Caille the Dal Cuinn northern Ui Niaill Cenel nEogain 166th King of Ireland was waiting for him and took him head on at Mag nOchtair near Cloncurry in Co. Kildare in Central Southern Leinster, were they had previously met before, and defeated him. This was to bring to an end his ambitions of any ideas of trying to gain the overall Kingship of Ireland for himself, as *101.Niall Caille was now the unofficial overall King of Ireland - without any opposition.  

842 The Viking Danes first appeared this year on Loch Ree / Ribh in the Upper Shannon River and also completed their time over the Winter period along the coast at Dublin in Co. Dublin in the north - east of Southern Leinster, and *101.Niall Caille as the Heremonian Dal Cuinn northern Ui Niaill 166th King of Ireland realising the seriousness of their overall attacks now formed the first alliance with the Viking King.

       105.Dungal the Heremonian Ui Laoghaire Ui Connla King of Ossory, died, who was a son of 104.Fergal the previous King of Ossory who had his territory in Co. Kilkenny in the south - west of Southern Leinster, and his son, 106.Carroll / Cerball mac Dungaile was to become the new King of Ossory, He too now realised the seriousness of the ongoing Viking attacks, and especially their various Viking settlements, especially along the coast of Southern Leinster, and to avoid disruption he was to marry his daughters to the Viking Chiefs, which then allowed him to better protect Southern Leinster, and this strengthen his position in the scheme of things, and that of his kingdom of Ossory and because of this attitude he was to reign there for 46 years until 888.

     Forindan and Diarmait the two previous candidates for the position of Abbot of Armagh in Co. Armagh in the Ulster Province were now working together in the Munster Province pushing the Law of Patrick to create peace, and 100.Felim mac Crimthainn the Eoghanacht Chaisil 23rd King of Munster met with both of them.

843 The Scythian Gaelic Picts in the Scottish Highlands now had no real overall leader and they had also moved from the central region in the north taking in the other Septs, so 95.Kenneth / Cinaed mac Ailpine - the Hardy the Gaelic Milesian Heremonian Ui Cobhthaigh northern Ui Niaill Cenel nEogain King of Albany besieged them and took their stronghold of Fortia in Perthshire. Due to his maternal connection to them also he was able to eventually combine both of these Celtic Septs north of Cheviot Get, the Scythian Gaelic Picts and the Scythian Heremonian Gaelic Scottii, to become the direct male ancestor of the future Kings of the Scottish Highlands. (The Orcades at this time were Celts who were on their own islands).

      104.Fergus the Dal Cuinn Ui Briuin Ai Siol Muireadhaigh Siol Cathail 36th King of Connacht, died, who was the son of 103.Fothad, the son of 102.Dub - Indrecht the previous 27th King of Connacht, descended from 101.Cathal the 23rd King of Connacht the direct male line ancestor of the Siol Cathail Sept, who had been one of the 2 sons of 100.Murray / Muireadach Muillethan the previous 18th King of Connacht the direct male line ancestor of the Ui Briuin Siol Muireadhaigh (Sil Murray) Sept.  

    104.Finsnechta became the new Dal Cuinn Ui Bruin Ai Siol Muireadhaigh 37th King of Connacht, who was another of the 3 sons of 103.Tomaltach, the son of 102.Murgal, one of the 4 sons of 101.Indrechtach the previous 21st King of Connacht, one of the 2 sons of 100.Murray / Muireadach the 18th King of Connacht the direct male line ancestor of the Ui Briuin Siol Muireadhaigh / Sil Murray Sept.

844 - 888 Carroll / Cerball, the Heremonian Ui Laoghaire Ui Connla King of Ossory who had his territory in Co. Kilkenny in the south - west of Southern Leinster was to use diplomacy to keep the overall control there by marrying his daughters off to the Viking Chiefs, which was within the Brehon Law. He then played one against the other, and this was to allow him to protect his territory also in the south - west of Southern Leinster, which went along way to further strengthen his own position and survival in Southern Leinster.

844 The Vikings attacked the monastery at Clonfert in Co. Galway in the south- west of the Connacht Province, and Turgesius the Viking King, who also had some of his fleet on Loch Ree in the Connacht Province also burnt the monastery at Clonmacnoise nearby in Co. Offaly in the north - west of Southern Leinster while his wife, Ota, defiled the altar there. 

      The first Murray / Muireadach who had been the Abbot of Monasterboice / Mainistir Bhuithin (St. Buithe's) monastery in Co. Louth in the north - east of Northern Leinster, died this year.

845 The Viking Norse at Baile Ath Cliath near Dublin were thoroughly defeated this year, and 1200 of them were slain by Carroll / Cerball the Heremonian Ui Laoghaire Ui Connla King of Ossory in the south - west of Southern Leinster, who was the son of Dungal who had used diplomacy and intermarriage to strengthen his position there. Despite this the Vikings had a victory against the Southern Leinster Septs in the mid - north - west of Southern Leinster at Dunamase / Dun Masc in Co. Laois.

       Forindan who was now the Abbot of Armagh in Co. Armagh in the Ulster Province was captured by the Vikings who were now set up at Limerick at Cluain Comarda in the mid - north - west of the Munster Province, which was the territory of the Heberian Eoghanacht Ui Fidgeinti Sept, where the Vikings at first broke and then then carried off the Shrine of Patrick, and they also attacked the Clonfert monastery again nearby further north in Co. Galway in the south - west of the Connacht Province.

      In a slight reprieve for Ireland from the Viking attacks Ragnar Lodbrok - of the Hairy Breeches, who was a Norwegian Viking from the ruling family in Denmark, attacked Paris from where he was driven off, so he then laid siege to Northumbria in England, where he was captured by the Saxon King Ella of Northumbria who had him killed by throwing him into a pit of snakes. His 4 sons, Sigurd / Sighurt - of the Snake Eye, Hvitserk, Bjorn - the Ironside and Ivar - the Boneless swore revenge for the way that he was killed, and Ivar - the Boneless, who was at this time carrying out raids in Ireland, turned his fury towards England instead.

846  *101.Niall Caille who had been the Dal Cuinn northern Ui Niaill Cenel nEogain 166th King of Ireland for 13 years, who was a son of *100.Aed Oirdnide the previous 164th King of Ireland, was drowned in the River Callainn at Milford / Ath an Mhuilinn in Co. Armagh in the south - east of the Ulster Province, at 55 years of age, in a battle against the Vikings, and his body was interred at the site of the Kilree High Cross in Co. Kilkenny in the south - east Southern Leinster. 

 846 - 860 *103.Malachy Mor 1st / Mael Sechnaill, (Descended from a devotee of St. Sechnall), the 26th Clann Cholmain King, who was the son of 102.Mulroney / Mael Ruanaid was the Dal Cuinn southern Ui Niaill Clann Cholmain 167th King of Ireland, and owing to the Viking onslaught throughout Ireland he was to be the first real High King of Ireland. His father had been a brother to *102.Conor / Conchobar the previous 165th King of Ireland, as both were sons of *101.Donough / Donnchad the previous 163rd King of Ireland, the son of *100.Donnell / Domhnall the 161st King of Ireland who had been the first to be a King of Ireland from the Clann Cholmain Sept. *103.Malachy 1st was to also be nominated as the 3rd High King of Ireland in the Annals of Ulster, as he was to finally rally the all out resistance against the Vikings raiders. He was to defeat the Danes at Skryne in Co. Meath and capture and kill Turgesius the Viking King by drowning him in Loch Nair / Owel, as he gathered up the Irish to take on the Norsemen foreigners / Cogadh Gaedhel re Gallaibh. Turgesius had pressed his luck too far when he had demanded the daughter of the King of Loch Owel, whose territory was between Derravagh and Mullingar, and when it was arranged that she would come to him she had brought along 50 warriors dressed as handmaidens, with the intention of finally removing him from the scene altogether. The demise of Turgesius was a great gain, as to what had been occurring previously, with no real concerted effort to bring their attacks to a halt, and this particular action showed once again what the removal of one negative individual, in an overall position of power, can do to turn around the whole nasty scene as the Danes were driven out.

      The Viking Norsemen from now on were to be attacked now by the individual Irish Septs, and the Danes from the east, during this Century, and had suffered a heavy defeat on Carlingford Loch / Loch Cuan in the Ulster Province. Although the Vikings were to have a minimal effect on the composition of the Irish Septs overall in the future, they were to also only effect the Irish language slightly with some 50 words, such as the introduction of Tir to change the name of the territory of Ulaid to Ulster, Laighin to Leinster and Mumhan to Munster.

     100.Felim mac Crimthainn the Eoghanacht Chaisil 23rd King of Cashel / Munster once again attacked the Clonmacnoise monastery in Co. Offaly in the north - west of Southern Leinster situated on the River Shannon in the territory of the Dal Cuinn southern Ui Niaill, and he ravaged it badly, and Forindan was ransomed and returned to Armagh.

      The Vikings at this time created a permanent settlement on the islands at Cork in Co. Cork in Southern Munster.

      With the growing strength of the Heremonian Ui Laoghaire Ui Connla kingdom of Ossory in the south - west of Southern Leinster, under the well organized Carroll / Cerball the King of Ossory a struggle for who now had the real authority there in Southern Leinster was once again on the agenda. The Heremonian Ui Laoghaire Cu Corb Septs in Southern Leinster who were now under the leadership of Aherne / Echthigern, defeated the men of Ossory at Uachtar Garadha under the leadership of Carroll , but despite this he was still able to defeat the Heremonian Ui Cobhthaigh Ui Felim Deisi Septs there nearby, who were under the leadership of  Downey / Dunadach, who was also a son of Dungal.

847 100.Felim mac Crimthainn the Eoghanacht Chaisil 23rd King of Munster, died, who was a son of 99.Criffan / Crimthann, a son of 98.Dubh Da Crich, a son of 97.Colman, one of the 2 sons of 96.Sechnussach, one of the 2 sons of 95.Fingen the previous 9th King of Munster, descended from 92.Felim / Fedelmid the 4a King of Cashel / Munster, one of the 2 sons of 91.Angus / Oengus mac Nad Froich who had been the 3rd King of Cashel / Munster, a son of 90.Nad Froich, one of the 7 sons of 89.Conall Corc.

    102.Olchobur became the new Eoghanacht Locha Lein 24th King of Cashel / Munster who was also the Abbot of Emly in Co. Tipperary in the north - east of the Munster Province, which may have also been why he was elected to the position. He was a son of 101.Kenneth / Cinaed, a son of 100.Congal, one of the 2 sons of 99.Mael Duin the previous 20a King of Munster, descended from 95.Aed Bennan the previous 9a King of Cashel / Munster, one of the 3 sons of 94.Criffan / Crimthann, descended from 92.Daui Iarlaithe the 3a King of Cashel / Munster, a grandson of 90.Coirpre Luachra the direct male line ancestor of West Munster / Iar Muma. who was also one of the 7 sons of 89.Conall Corc the 1st King of Cashel / Munster.

848 Forindan was replaced as the Abbot of Armagh in Co. Armagh the Ulster Province once again by Diarmait.

     104.Finsnechta the Dal Cuinn Ui Briuin Ai Siol Muireadhaigh 37th King of Connacht, died, who had been one of the 3 sons of 103.Tomalty / Tomaltach, a son of 102.Murgal, one of the 4 sons of 101.Indrechtach the previous 21st King of Connacht, which was to see his particular male line end with him, Their Ui Briuin Siol Muireadhaigh line would be continued on to the future O Connor Kings of Connacht through one of his older brothers, 104.Maurice / Muirgius who had previously been the 31st King of Connacht.

     106.Lorcan was now the Heremonian Ui Laoghaire Cu Corb Ui Dunlainge Ui Muireadhaigh 27th King of Leinster, whose father had been 105.Kelly / Ceallach the previous 24th King of Leinster, one of the 2 sons of 104.Bran Ardchenn the 24th King of Leinster, a son of 103.Murray / Muireadach the 18th King of Leinster who was the direct male line ancestor of the Cu Corb Ui Muireadhaigh Sept.

      102.Olchobar the new Eoghanacht Locha Lein 24th King of Cashel / Munster besieged the Vikings who had set themselves up at Cork in Co. Cork in Southern Munster.

      The Irish Septs had by now defeated the Vikings four times, twice under 103.Malachy Mor 1st / Mael Sechnaill the Heremonian Dal Cuinn southern Ui Niaill Clann Cholmain 167th High King of Ireland, with two of the victories in Meath / Midhe in the south - east of Northern Leinster with one at  Skryne, and another 2  under the Heberian Eoghanacht Septs near Cashel in Northern Munster. All of the Irish Septs now considered the tide was finally turning against the previous Viking onslaught and the monks now went to France to seek free passage to Rome, but this was not to be as a further 120 Viking ships suddenly appeared around Ireland, and they also began to use the rivers, especially the River Shannon to plunder further inland territories.

850 The Danes who were from Denmark also began to bring into Ireland fermented liquor, which became known as Whiskey / Uisge (the water of life) and they also began asettlement in Limerick in the mid - north - west of the Munster Province at the outlet of the River Shannon into the Atlantic Ocean to carry their raids further into the inland territories. The Vikings (Gall) (foreigners or Geinte (pagans) by their dialect, now called Eire (Ire Land), and the Irish / Scottii on Alba / Scottish Highlands, and their territory there became Scot Land. Some Hiberno - Norse intermarriage was also occurring, especially in the north as the Irish Chiefs and Kings began to form their own individual alliances to suite their particular purposes to survive.  (Waterford on the south - east coast of the Munster Province was now also settled by the Vikings).
