Dictionary of National Biography, 1885-1900/Ibhar
IBHAR or IBERIUS, Saint (d. 500?), bishop of Begery or Begerin, born early in the fifth century, may have belonged to the tribe of the Ui-Eachach Uladh in Iveagh, co. Down. He was probably a pupil of St. Patrick, and received the name Ibhar on becoming a Christian. He lived at first in the Arran Islands in Galway Bay, afterwards on Geshille Plain, King's County, then in the island of Begerin in Wexford Haven. He kept a school, and soon gathered monks around him, and his memory is preserved in various local traditions. He died at Begerin about A.D. 500. He is locally known as St. Ivory, and is commemorated on 23 April.
