Cauvin was a man of hard and severe character, occupied a prominent position as apostolic secretary to Charles de Hangest, bishop of Noyon. He also served as proctor in the Chapter of the diocese, and fiscal procurator of the county. He lived on intimate terms with the best families of the neighborhood.
His wife, Jeanne Lefranc (daughter of an innkeeper at Cambrai), was noted for her beauty and piety. She died after giving birth to five (some sources say six) children, with three sons and two daughters. A son, christened Jean Cauvin (or Chauvin) but better known as John Calvin, would become a major influence in Protestant Reformation and theology. After Lefranc's death, Cauvin married a woman with whom he would have two daughters.
He became involved in financial embarrassment, and was excommunicated, perhaps on suspicion of heresy. He died May 26 (or 25), 1531, after a long sickness, and would have been buried in unconsecrated soil but for the intercession of his oldest son, Charles, who gave security for the discharge of his father’s obligations.
