HISTORY. 
967. “ Aengus O’Robhartaich [O'Rafferty], anchorite of Derry-Calgach, and Kinaeth 
Q’Cathmhaoil [now anglicized Camphill, Campbell, and Caulfield], erenach of Derry-Calgach, 
died within the same month.” Both these families exist in the county. 
973. “ Fogartach, abbot of Derry-Calgach, died.” 
983. “ Uissine [Ossian] O’Lapain, erenach of Derry-Calgach, died.” 
985. “ Maolkiaran O’Maighne, coarb of Columbkille, suffered martyrdom from the Danes 
of Dublin.” 
988. “ Dunchadh O’Robhacain, coarb of Columbkille and of Adamnan, died. The name 
of Rogan, which is still found in Derry, is probably modernized from this.” 
“ Dubdaleth, coarb of Saint Patrick, assumed the coarbship of Columbkille by the suffrage 
of the Irish and Scots, that is, as Colgan explains it, supreme moderator of the monasteries 
of the congregation of Columbkille in Ireland and Scotland.” 
998. “ Dubdaleth, the son of Kellach, coarb of Saint Patrick and Columbkille, died on the 
2 nd of June, in the 83rd year of his age.” 
1006. “ Muireadhach Mac Criochain [now Creighanand Cregan] resigned the coarbship of 
Columbkille, to apply himself more sedulously to devotion.” 
1010. “ Muireadhach Mac Criochain, coarb of Columbkille andAdamnan, alearned doctor and 
bishop— a son of purity—lecturer of divinity at Armagh, and intended coarb of Patrick, died in 
the 84th year of his age, on the 5th of the kalends of January, on Saturday night, and was 
interred with honor and veneration in the cathedral church of Armagh, before the high altar.” 
1022. “The coarb of Columbkille [Malone O’Dornan] was present at the death of Ma- 
lachy the Great, the son of Donnell, king of Ireland, at Cro-inis an Island, in Lough Ainin [now 
Lough Ennel].” 
1025. “Malone O’Toran, or Tornan [Dornan], coarb of Derry-Columbkille, died. This 
is the first notice in the annals in which the name of Derry appears as Derry-Columbkille.” 
1040. “ Maolmurry O’Ochtain, coarb of Columbkille and Adamnan, died.” 
1057. “ Robhartach, the son of Ferdomhnach, coarb of Columbkille and Adamnan, died.” 
1061. “ Muireadhach O’Maolcolum [now O’Malcolm], erenach of Derry, died.” 
1062. “ Gilcreest O’Muldorry, coarb of Columbkille, both in Ireland and Scotland, died. 
This name is still found in Derry and Donegal. They were princes of Tirconnell preceding the 
O’Donnells.” 
1066. “ Dunchadh O’Daimhin [now Devine], coarb of Derry, died.” The family of 
O’Daimhin, or Devine, was one of the tribes of the Kinel-Owen, and is still numerous in Derry 
and Tyrone. 
1096. “ Owen O’Cearnaigh [Kearney], erenach of Derry, died on the 18th of the kalends of 
January [15th of December].” 
1098. “ Donnell O’Robhartaich [Rafferty], coarb of Columbkille, died.” 
1112. “ Congalach, grandson of Cucaille, erenach of Derry, died after great penance in the 
94th year of his age.” 
1120. The celebrated Gilla Mac-Liag, the son of Rory, better known by the latinized 
name of Gelasius, became, at the age of 33, erenach, or, as Colgan and others suppose, coarb or 
abbot, having been previously erenach. But it has been already shewn that these terms 
were frequently synonimous, and in all the ancient Irish authorities Gelasius is invariably 
called erenach, though it appears certain that he exercised the authority of abbot: hence Dr. 
Lanigan had no authority to state that erenach meant archdeacon, and that Derry was conse¬ 
quently then considered as an episcopal see. It may not be improper also in this place to correct 
another erroneous assertion of this usually accurate and learned writer, namely, that Colgan was 
mistaken in stating that Niell, or Nigel, had again obtruded himself into the abbacy, or, as Dr. La¬ 
nigan has it, archbishopric of Armagh, on the retirement of Malachy, and previously to the eleva¬ 
tion of Gelasius to that dignity. Had Dr. Lanigan carefully consulted the Annals of the Four 
Masters he would have found that Colgan had authority for his statement, viz. : —

“ A change of abbots at Armagh, viz.: the erenach of Derry, in the place of Niall, the son 
of Hugh.” 
“ Gelasius filled the episcopal chair of Armagh 38 years, and died in the 87th year of his 
age, on the 27th of March, 1174.” 
1126. “ Fionn O’Conaingen, erenach of Derry for a time, died.” He was probably the 
predecessor of Gelasius.” 
1129. “ Gilla Colmain O’Kellaigh, a principal presbyter of Derry, died.” 
1134. “ Bebinn, daughter of Cuchaille, abbess of Derry, died on the 23rd of December.” 
1150. “ Maoliosa O’Branain [Brannon], erenach of Derry-Columbkille, who was the most 
prosperous and munificent man in the north of Ireland, died.”
