I would guess that this Jeanne Galthier (Gauthier)-Rahir (b. ca. 1550?) did marry Denis Briere, and that she was the mother of Renee Briere (b. ca. 1570; first wife of Denis Cloutier). If so, she would therefore be Denis Cloutier's mother-in-law, not a second wife. The actual second wife of Denis Cloutier is apparently Jeanne Galthier (b. 1580's?), and she has been confused with Jeanne Galthier-Rahir (b. ca. 1550). That they both have the same name and both married someone with the first name Denis could explain the confusion. So it would probably be best to disconnect Jeanne Gauthier-Rahir from Denis Cloutier. A wikitree profile could then be created for Jeanne Galthier (as second wife of Denis Cloutier). I am wondering if this second wife Jeanne (b. 1580's) was a niece of Jeanne Gauthier-Rahir (b. ca. 1550).
