Saint Mac Oigi, the Priest, September 19

Among the saints remembered on the Irish calendars on September 19, is a priest known only by his patronym, as Canon O'Hanlon explains:

St. Mac Oigi, Priest.

The particular name of this saint does not appear to have been preserved, for he is only called "the son of Oig." In the published Martyrology of Tallagh, we read, that veneration was given at this date to Mac Oigi. The contracted word Sac. follows this announcement, and from its usual form of application, we may infer he was a Priest. In the manuscript copy of the Book of Leinster, in like manner, he was distinguished as Mac Cuigi, a Priest.
