I am not sure what towns are meant to be 600 km apart.
As far as I understand, the following two couples have Canadian descent:
- Jehan Terriau and Perrine Rau (spelled as they appear in the 1671 census linked on Perrine's profile). They are supposed to be from Martaizé (then in Loudunais, part of Anjou, now in Vienne 86), although I could not find where this comes from. Both migrated to Acadia around 1635, probably after their marriage.
- Pierre Brouillard and Perrine Bourgault, from Chambon (then in Touraine, now in Indre-et-Loire 37), grandparents of Charles Brouillard, who migrated to Québec around 1685, and has a well-documented fichier origine.
Martaizé and Chambon are just 65 km apart. Still, it seems very unlikely that Perrine Rau and Perrine Bourgault be the same person.
References to Chalons (or Chalon, whichever), or to Chambon-sur-Lignon, etc., are just fanciful transformations of Chambon.
Finally, Marguerite Pognon seems to be a complete fabrication, maybe inspired by a couple Jean Brouillard and Marguerite Pognon that existed in Dun-sur-Meuse (now that's really 600 km away from Chambon, moreover that marriage took place in 1672).
