Eoghanachta of Munster - 24.A

 100.Felim mac Crimthainn the Heberian Eoghanacht Chaisil 23rd King of Cashel / Munster raided the Heremonian Ui Cobhthaigh Dal Cuinn "southern" Ui Niaill kingdom of Delbna Bethra again, killing most of the monastic community and burnt everything except the church, and then attacked the monastery again also at Durrow in Co. Laois in the mid - north - west of Southern Leinster that had been a rival to Clonmacnoise in Co. Offaly in the north - west of Southern Leinster for the favour of the Heremonian Ui Cobhthaigh Dal Cuinn "southern" Ui Niaill Clann Cholmain Septs, as it had aided a previous Heremonian Dal Cuinn Ui Niaill King of Ireland against the Munster Province in 766 AD. 100.Felim's hostility to Clonmacnoise, which was situated in the territory that was in Conn's Half / Leith Cuinn was unremitting, as the kingdom of Delbna Bethra belonged to the Fortuath Clann who were subject to the "southern" Ui Niaill and who had there own sub - King who was also subject to Clonmacnoise. They also had possession of the monastery at Lemanaghan / Liath Manchain in Co. Offaly, which had been originally a Munster foundation of St. Manchan that may have also controlled Gallen, which was also situated in Co. Offaly. It was patronized by the Heremonian Ui Cobhthaigh Dal Cuinn Colla Da Crioch Ui Maine Kings from the Connacht Province, the Heremonian Ui Cobhthaigh Dal Cuinn Ui Briuin Kings of Connacht and the Heremonian Dal Cuinn "southern" Ui Niaill Kings of Midhe / Meath in Northern Leinster. It also had subject churches on both sides of the River Shannon and also on Loch Ree, who all suffered from the ongoing Viking raids as well as those from the ever - consistent 100.Felim mac Crimthann. Co. Westmeath and Co. Meath in Northern Leinster were once the Midland Province in Conn's Half until *83.Conn - of the Hundred Battles the Gaelic Milesian Heremonian 110th King of Tara / Ireland had joined it in with Southern Leinster after the death of 83.Mogha. Southern Leinster was always to be a sore point with the Munster Heberian Kings and a never - ending source of dispute between the Heberians and the Heremonian Ui Cobhthaigh Dal Cuinn Septs. Heremonian Kings had imposed an onging tribute / borumha in Southern Leinster on the Heremonian Cu Corb Septs, who were also originally from the male line of 59.Ugaine Mor through 84.Cu Corb even before the time of *80.Conn - of the Hundred Battles. They were also imposed on the Heremonian kingdom of Ossory in the south - west of Southern Leinster who were basically sandwiched in between Southern Leinster and Munster who were also originally in Mogha's Half.

835 AD. Forindan / Forannan the Abbot of Armagh in the south - east of the Ulster Province ousted Diarmait O Tiernan / Ua Tigernain from Armagh who was nevertheless to continue to contest the position for the next 17 years as disputes had arisen shortly after the inauguration of *101.Niall mac hAeda Caille the Gaelic Milesian Heremonian Ui Cobhthaigh Dal Cuinn "northern" Ui Niall Cenel nEoghain 166th King of Ireland, who began also trying to assert his overall authority in Mogha's Half in Southern Leinster. He had also nominated 105.Bran mac Faelan as the new Heremonian Ui Laoghaire Ui Lughaidh Cu Corb Ui Dunlainge Ui Dunchada 25th King of Leinster, but to enforce this he even had to subdue his own kinsmen from the "southern" Ui Niaill Septs so he ravaged their territory in Meath in Northern Leinster as far as Tech Maelchonoe, which was the site of another monastery in their sub - kingdom of Delbna Bethra. During that campaign the men from the Munster Province were to kill Fergus mac Bodbchada of Carraic Brachaide from Inishowen in Co. Derry in Northern Ulster who was one of his "northern" Ui Niaill Chiefs.
