(Magheranoidhe is also rendered Murneave or Murnevin).
Nephew of St. Ibar, the apostle of Wexford (a predecessor and contemporary of St. Patrick), flourished 570-620. He was the son of Cormac, King of Leinster, and he founded numerous churches in the district of Ui Cennselaigh, almost conterminous with the present County Wexford and Diocese of Ferns. His principal monastery was at Magheranoidhe, subsequently known as "Abbanstown," today, Adamstown; but he also founded an abbey at Rosmic-treoin, or New Ross, which afterwards became famous as a scholastic establishment. He died 16 March, 620. (See also ST. ABBAN OF NEW ROSS.)
