Louth, is explained if we suppose that during his episcopate the see was 

 transferred from the former to the latter place. 1 It is at any rate certain 

 that his successors up to the last decade of the century had their see at 

 Louth, and ruled over the diocese of Uriel, a district which contained the 

 greater pare of the diocese of Clogher, in its present extent, together with 

 the Count}" of Louth. 2 Thus we have St. Bernard's authority for the state- 

 ment that on the death of Gillacrist one Edan, whom the Irish writers call 

 Aedh Ua Caellaidhe, was appointed to fill his place :? and Edan is described 

 in more than one charter as Bishop of Louth, 1 and in the record of his death 

 as Bishop of Uriel 5 He died in 1182. In 1184 another Bishop of Louth 6 is 

 in possession — Mael Isu Ua Cerbhaill In recording his death in 1187 the 

 annalists style him Bishop of Uriels His successor was Gillacrist Ua Mueearan, 

 Bishop of Louth and of Uriel, who died in 1193.- After him comes a bishop 

 of whom we know nothing more than that his surname was Ua Mael Ciarain, 

 and that he died Bishop of Uriel in 1197. 9 



It appears that about the year 1200 the see was once more transferred : 

 for after the twelfth century we hear of no more Bishops of Louth ; and the 

 title Bishop of Uriel almost disappears from the Annals. 10 The successor of 

 Ua Mael Ciarain seems to have been Gilla Tighemaigh Mac Gilla Bonain. 

 whom the annalists call Bishop of Clogher. and who died in 1218. u Two or 

 three years before his death, Eugenius, Archbishop of Armagh, held a synod 

 at Drogheda, 1 - wbich proves that by that time the County of Louth had

 his successors, he was Bishop of Uriel.

Annals of Ulster speak of bishops of Uriel in 1356 and 1369 : but clearly this
