So first we must establish to what extent the North of Ireland was the heart of the reform movement? Well in the 12th century the ecclesiastical reform movement can be identified from two main strands of that reform :-
1) namely the tightening of the Diocesan structure
2) and the founding of the new religious orders in Ireland.
This highlights two stories here:
1) the impact of the general reform of the Irish Church in the
12th C in Ireland
2) and the rise of the family of the O‘Cahan’s to control the kingdom in Ciannacta and who go on to patronise Augustinian Canons.
These two stories take place at much the same time, so it is reasonable to ask whether we should connect them together. If we do, then it is at the Abbey church of Dungiven that they meet.
