Yvo

Ivo of Kermartin, TOSF (1253 – 1303), also known Yvo, Yves, or Ives (and in Breton as Erwan, Iwan, Youenn or Eozenn, depending on the region, and known as Yves Hélory (also Helori or Heloury) in French), was a parish priest among the poor of Louannec, the only one of his station to be canonized in the Middle Ages. He is the patron of Brittany, lawyers, and abandoned children. His feast day is 19 May. Poetically, he is referred to as "advocate of the poor".
