Brigh (Lat. Briga), Saint,
is given in Irish martyrologies as the name of a saint of Coirpre, commemorated January 7. She is thought by some to be the daughter of Feargna, a noble matron, who assisted St. Patrick on the banks of the Liffey (Evrinus, St. Patrick, 3:9), by others the sister of St. Brendan of Clonfert. If daughter of Feargna, she was probably a Palladian Christian, and lived at Glashely, near Narraghmore. See O'Hallon, Irish Saints, 1:300 sq.
