Prud'homme's original land grant adjoined that of Michel Chauvin, just outside the fort. Earlier in 1650, Prud'homme discovered on a trip to France that Chauvin was a bigamist, having married Louise Delisle on 10 August 1637 in Ste-Suzanne, Mayenne, France and subsequently Anne Archambault, daughter of Jacques Archambault, on 27 July 1647 in Paroisse Notre Dame, Québec, a celebration Prud'homme had attended. Prud'homme informed Governor Chomedy of this fact, which led to Chauvin's banishment from Ville-Marie and the annulment of his marriage to Anne Archambault..
