St. Dubricius' grandfather was Pepianus Clafrog, King of Ergyng (a kingdom in southeastern Wales), who was afflicted by leprosy and foaming at the mouth. Returning from battle, the king discovered that his daughter Eurddil was pregnant and ordered her to be put in a sack and thrown headfirst into the River Wye. After multiple attempts, wherein she washed up alive on the bank, he ordered her burnt alive in a pyre. However, when Pepianus' messenger checked for bones the next day, he found Eurddil still alive, sitting with young Dubricius in her lap. Hereafter a stone was left to mark the place of his birth, which was named Madle (mad, good; lle, place) because a holy man was born there.
