Map of France and surrounding areas.

This is a more detailed map. You can easily see the Ticino, Switzerland,
as well as the areas of Provence where Chiassons would have migrated
to and/or through, on their journey to other parts of France including the
fertile Garonne Valley. Pierre Chiasson farmed just north of where you
see Libourne on the map. This is where Guyon was born and lived until
he was 12 years old. This family then moved to La Rochelle in 1650.
