1061 - 1070 AD
110.Dermot / Diarmait mac Mail na mBo - of the Many Cattle the Heremonian Cu Corb Ui Cheinnselaig 51st King of Leinster by now had well and truly regained the right to the Kingship of Leinster for the Ui Cheinnselaig Tuath (Family region), and possibly also the overall authority now in Ireland, and unfortunately this would now lead on to his descendant, the infamous 113.Dermot / Diarmait mac Murrogh na Gall - of the Foreigners who would later on be the main catalyst for the Anglo - Norman English Invasion in Ireland in 1167 AD.
Malcolm O Lynch who was the Heberian Dal gCais Ui Bloid priest at Clonmacnoise in Co. Offaly in Southern Leinster, died.
1062 AD There would now be a drastic change of dynasties in the Heremonian Dal Cuinn "northern" Ui Niaill Cenel nEogain as the O / Mac Loughlins / Mheic Lochlainn were from now on to dominate the Cenel nEogain Kingship of Aileach in the Ulster Province for the next 130 years, while their Cenel nEogain kinsmen, the previously dominant O Nialls, became the Cenel nEogain Kings of Teloch Og only, there in the Ulster Province, and such a long sojourn out of the Derb Fhine (True Family) would have previously ended any chance of recovery the O Niall's had of eligibility under the Brehon Law of succession within 4 generations. Once again because of the previous ongoing Viking disruptions and the forthcoming Anglo - Norman English Invasion's combined effects on the Brehon Law also the fortunes of the O Nialls would never the less rise again after this very lengthy period of time.
1063 AD *106.Donogh mac Brian, (the son of *105.Brian Boru and 110.Gormlaith), the Heberian Dal gCais 42nd King of Cashel / Munster was now deposed from this position also, and his son, 107.Murrogh / Murchad - of the Short Shield O Brian was to become the new 42a King of Cashel / Munster until 1068 AD.
Conaing O Hara died this year at Clonmacnoise monastery in Co. Offaly in Southern Leinster.
1064 AD *106.Donogh mac Brian the previous Heberian Dal gCais 42nd King of Cashel / Munster, and 176th King of Ireland - with opposition (the son of 105.Brian Boru and 110.Gormlaith), died this year in Rome. He had been a half - brother to 106.Teague mac Brian the father of *107.Turlogh O Brian, who was now the 43rd King of Northern Munster / Thomond, as both had been sons of *105.Brian Boru the direct male line ancestor of the Ui mBriain Sept, and the previous Heberian Dal gCais 175th High King of Ireland. *107.Turlogh O Brian would eventually become the Heberian Dal gCais Ui mBriain King of Cashel / Munster and 178th King of Ireland until 1085 AD.
The deceased Murtogh / Muirchertach O Niall the Dal Cuinn "northern" Ui Niaill Cenel nEogain King of Teloch Og in the Ulster Province would be the last of the Heremonian Dal Cuinn "northern" Ui Niaill Cenel nEogain O Nialls to be recorded in the Annals of Ulster, while on the other hand from this date until 1160 AD their close kinsmen the O / Mac Loughlins / Mheic Lochlainn Sept would be the only Dal Cuinn "northern" Ui Niaill Cenel nEogain Sept to be recorded in the Annals of Ulster.
108.Ardgar O Loughlin / Lochlainn who had become the Dal Cuinn "northern" Ui Niaill Cenel nEogain 44th King of Aileach, in the Ulster Province, died this year, who was to continue on the O / Mac Loughlin direct male line in Ulster though his sons, 109.Murray / Muireadach O Loughlin who was to become the 53rd King of Aileach, and especially through his other son, *109.Donnell O Loughlin who was to not only become the 51st King of Aileach, but also the 179th King of Ireland. (There is dispute over which one of the Cenel nEogain 107.Lochlanns was his actual father, although both were descended from *102.Aed Fionn Liath the previous 168th King of Ireland.
1065 AD Echnearcach
mac Firbis
the previous
Viking King of Dublin,
also
died this year in
Rome.
1065 - 1071 AD Cu Ulaid Ua Flaithri was to be the Heremonian Dal Fiatach Leth Cathail King of Ulaid in his territory of Ulidia in the east of the Ulster Province, who was descended from 98.Cathal, a son of 97.Murray / Muireadach, the son of 96.Angus / Oengus, one of the 2 sons of 95.Mael Cobo who had been the previous 13th King of Ulaid, descended from 90.Forgg mac Dallain who was descended also from *Fiatach Fionn (Daire) the Heremonian Ui Cobhthaigh King of Ulaidh / Ulster and the 103rd King of Ireland the direct male line ancestor of the Ulaidh Dal Fiatach Septs who had reigned from 36 - 39 AD.
1067 AD By now the position of the other Heremonian Dal Cuinn Septs in the Connacht Province
in the west of Ireland had
been weakened by their kinsmen, the
Heremonian Dal Cuinn "northern" Ui Niaill
Septs' expansion into their territory also in the north, and
they were also involved in internal
Dal Cuinn Ui Briuin dynastic struggles
of their own and
110.Diarmait mac Mail na mBo
- of the Many Cattle the Heremonian Cu Corb
Ui Cheinnselaig
51st King
of Leinster took the opportunity of their internal conflicts to gain
further
overall
authority for himself there in Connacht Province also, but he soon
found out that he had to withdraw from there.
