source “One Hundred French Canadian Family Histories” by Phillip J. Moore.
Most people of French Canadian heritage descend from this family of old Perche. Jacques Guyon is the earliest Guyon we can claim as an ancestor. He witnessed a document executed in Tourouve, Monday, January 6, 1579, and died before September 29, 1623. He and his wife Marie Huet married before 1583. They had at least two children, Marie born in 1588, and Jean in 1592. Jacques was unable to sign his name.
