Jean Guyon[G, en.WP] is one of those historic figures you do not hear much about. He was a master mason, accomplished some works which still exist today (not a small feat), immigrated to Nouvelle-France[fr.WP].
But his primary contribution to history was fathering 10 children, of whom 8 produced another generation. Today it is estimated that three of every four persons of #French-Canadian heritage can trace their lineage to Jean Guyon and his wife Mathurine Madeleine Robin[G].
The Guyon surname altered regularly in the past four centuries. Some of the descendants have the name Dion, Despres, Dumontier, and Lemoine, and in basse-Louisianne[fr.WP], now part of Louisiana and Texas and neighboring states, Derbanne and Berban. And these are just the direct male descendancies. Such disparate figures as Canadian Politician Stéphane Dion and musician Celine Dion are cousins who trace back to Claude and Jean Guyon, respectively, sons of the senior Jean Guyon.
Jean Guyon was the son of Jacques Guyon[G] and Marie Marguerite Huet[G], of #Perche (now Orne), #France. He took up the masonry trade, rising to become a master guildsman. He was enticed to #Nouvelle-France by Robert Giffard[R] under a three-year contract in exchange for a one thousand arpent arrière-fief; an arpent being a measurement of area slightly smaller than an acre.
This land was under the seigneurial system of Nouvelle-France[en.WP], meaning it was held in fiefdom, a form of noble tenure on the land. According to court records, Jean Guyon disputed that his land owed fealty and taxes to Robert Giffard as well as the king, but the court disagreed after a 9-year series of skirmishes. Similarly, his heirs engaged in a protracted dispute after his death in 1663.
