St Domnoc

Another old Irish saint is commemorated today, St Domnoc or Modomnoc, occasionally Anglicized as Dominic. Here is what Mrs D'Arcy has to say about him in The Saints of Ireland

Domnoc, of the royal line of O'Neill, studied under St David of Menevia in Wales and then returned to become a solitary at Tibraghny in Kilkenny. He had taken care of the bees at Menevia and at the time of his departure they swarmed determinedly about his boat. He tried three times to return them to their hives, all to no avail. At last David told him to be gone, bees and all, with God's blessing. This is supposedly the beginning of the cultivation of honey in the monasteries of Ireland.

The Catholic Ireland site has a little more about him here.
