He is around seven years older and Yves’ parents entrusted him with his instruction. At more than ninety years old, he will be the first witness in the canonization acts. He always lived in his Manor of Kerc’hoz in the parish of Pleubian, except when during the years when he went with him for studying in Paris and Orléans. He has known him since his childhood, then, as well as his parents for he attended their wedding too. He says something very important during the trial of canonization about Saint Yves’ childhood. Indeed, Yves’ mother told him, in Kermartin manor that she was bewared by a dream that her son would become a saint; just Yves’ father, Yves himself were present at that moment.
