Efrddyl

Saint Efrddyl was the daughter of Peipiau Clavorauc, king of Ergyng in Wales, and the mother of Saint Dubricius (Dyfrig). All that is known of her is found in the Life of Saint Dubricius. Her father, learning that she was with child, grew angry and ordered that she be thrown into the river in a leather sack; the waves cast her up on the bank. He then ordered her to be burned alive, but she gave birth on the pyre, in the midst of the flames, which would not touch her. Hearing of the marvel, the king sent for his daughter and the infant.

Her name appears in the sources also as Ebrdil, Evrdil, Eurdyl or Eurdila.
