My mother's father's father, who emigrated from to Quebec to Illinois sometime in the late 1800s, changed his name from Dutour to Cadore, and became Frank rather than Francois. Family legend has it that he was on the lam, and I haven't been able to find out more about him.
There are Cotes in my wife’s line. We have some pictues of some. Lavoie (de la Voie and variants) and Prince, Oulette, Lessard, and a whole mess of hard to spell names. Most from the area on the south shore of the St. Laurence near Rimouski and on her mom’s line, Acadia near what is now Annapolis in Nova Scotia. Around Ste Anne de Beaupre NW of Quebec City as well.
What is cool is going there and finding these plaques with family names ALL OVER them:
