 Hughes’ "Early Christian Ireland" notes that Patrick set up his church in Ulster, a province that still must have spread over much of Northern Ireland, and contained Armagh.Bishop Aedh, the patron of the "Vita", was originally from the Irish midlands but had moved to Armagh.Bishop Aedh had then merged his church with the Paruchia Patricii (the confederation of Patrician churches) in Armagh anytime from 661–668.
