Would you know if all of the above were descendants of Joseph Gaudin dit Tourangeau, from Touraine, France and married to Marie-Josephte Hery dit Duplanty. Marie-Josephte was the grand-daughter of Pierre Lamoureux dit St-Germain and Malia-Marguerite Pigarouiche, a Native Amerindian of the region of Montreal. Joseph Gaudin dit Tourangeau and Marie-Josephte Hery are my sixth (6th) great grand-parents. Their daughter Marie-Louise Tourangeau married Ignace Andre dit St-Amand at Lake of Two-Mountains, west of Montreal on April 7, 1761. Parallel to this branch, have several ancestors present at Michilimackinac circa 1720s, with a good portion marrying early Metis (French-Amerindian).
