I am just starting to research my Guyon ancestry. My great-great grandfather was Eustache Augustin Guyon who married Celeste Mercier.Eustache and Celeste married on 16 Jan 1816.Eustache was born on 9 Mar 1795 in St-Hyacinthe.He died on 22 Apr 1880 in Ste-Cecile-de-Milton.
Eustache's parents were Jean Baptiste Guyon and Marie Reine Morin.
I believe Jean Baptiste's parents were Charles Guyon and Catherine Halaire/Allaire.
I suspect there is significant research already done on the Guyon family.Can somebody steer me in the right direction or provide the trail back to earlier Guyon generations?
