Catherine de la Rochelle, was a "woman of devotion" as she is called in a receipt from the city of Tours.

We know that on July 4, 1431, at the procession of St. Martin, Jean Graverent, the Inquisitor, delivered a violent discourse against Jeanne. He recalled also that Brother Richard had had in his train four women, three of whom had been taken, namely, the Maid, Pierrone the Breton woman, and her companion, and Catherine de la Rochelle "who said, that when the sacrament of Our Lord's body was celebrated, that she saw marvels of the high secrets of Our Lord God."

We find that, on September 10, 1430, the city of Tours paid the Augustinian Jean Bourget who had been at Sens, in the month of August, on business with the King and the council, to carry letters to defend itself from the calumnies that this said Catherine had spread about the city and its inhabitants.

Catherine appeared at Paris before the church court and she declared that "Jeanne would have left her prison by the aid of the Devil if she had not been well guarded."
