When I wrote about the abduction of Anne O’Donel to Glass Island, Lough Conn in 1785, I was unaware of the story of the Bishop who was reputedly murdered there. Josie Kilduff, a student at nearby Lisaniska National School, describes how the Franciscan monks invited the Bishop of the diocese to Glass Island to elect a new Abbot to their Monastery. The monks also invited the Bishop to remain on the island for a while, but not long after, they found him murdered there.
Further distress afflicted the monks after a monster reputedly came in from the lake and destroyed their crops. They eventually abandoned the island. Josie also states that the monster appears in the lake before a drowning.
Josie’s story was recorded as part of the recently digitized School’s Collection in the National Folklore Collection of the late 1930s under the title, “The Franciscan Monastery of Glass Island in Lough Conn.” The only other reference I found to a monastic settlement in Lough Conn is to the nearby Errew Abbey at Crossmolina.
