Móenu
Móenu, Bishop of Clonfert, died 1 March 572.
Maeineann was a nephew of Brendan, and seems to have acted as his Coadjutor and head of the monastic school. It is not know if he was at any time its abbot, or if this was an office exclusive to Brendan.
Maeineann is the first recorded bishop of Clonfert. At times, his successors would also be known as bishops of Uí Maine, the kingdom within which Clonfert was located. The next known bishop was Cummian Fota, who died in 661, so a number of holders of the office would appear to be unknown.
