Pierre Campion and his wife Marguérite Hénault lived in the parish of St-Nicaise in Rouen (above). We know only one one daughter, Marie, born about 1654 and sent to Québec as a "fille du roi" in 1670. She brought a dowry of 200 livres with her, as well as the usual 50 livres supplied by the king, so she was evidently neither poor nor a prostitute. She married Mathurin Dubé in September 1670, shortly after her arrival (at St-Famille in the Île d'Orléans), and died sometime between 1694 and 1704 in Rivière-Ouelle.

Marie and Mathurin Dubé had sevem children; see Dubé. Their son Laurent was a great-great-great-great-grandfather of Marie Eva Jean Martin.

There are two other Campion families in Nouvelle-France, one from Brittany, the other from Calais - so probably not related.
