I think the online barony map is original. My opinion based on its decoration, in the style of the original maps. Also, copies I have seen, some on the TCD site, are stated to be copies on the map itself (and less decorated).
As for ordination, I don't think ordination in Ireland was common at all. There were no seminaries in Ireland at the time, or for well over 100 years later, so priestly training and ordinations typically (always?) occurred in the Irish colleges on the continent.
Or perhaps you mean consecrated, if you are speaking of the bishop? That could have occurred in Ireland, and would necessarily have been in secret - death penalty for Catholic bishops at the time....
