Hi, in fact the error you report is simply a bad misunderstanding of the name of Marie Brabant. The priest wrote in fact in the parish register "Branban" but it looks like Breuban, but rest assured, it sure is Marie Brabant. You have to understand that the priest had to write the names as they were told to him as nobody among the parents or the married couple could read or write. This explains that.
FYI, Regis married Catherine Brabant on May 4th, 1846 in St-Polycarpe. Upon the death of Catherine on Nov. 17th, 1853, he remarried Florence Lamarre on Aug. 14, 1854 in St-Polycarpe.
