Hi my maiden name is Harteau; also known as harteaux/hurteaux/huneau/l'heureaux/heroux and a million others.
My ancestors came from Laprairie Canada to Wisconsin with either the Hudson company or the American Fur Company and helped with trading at the new fort at La Baye now Green Bay Wisconsin. I have three brothers Joseph b. 1803, Louis b. 1808 and Michel/Michael b. 1812. Louis married an women named Charlotte Grignon and her mother was the daughter of an Indian Chief. It is said that there were 21 siblings and that their father was named Michel. I have nothing documented. I have seen each of there last names spelled a million different ways. But I do know that Louis Harteaux or L'heureaux lived on the Fort Howard Indian Reservation in 1860.
Joseph married Mary Gorham who's father was David Brass Gorham who was murdered at Duck Creek
Louis married Charlotte Grignon; Daughter of Louis Grignon and Theresa Rankin; Charlotte's step father was John Lawe a famous captain and judge in Wisconsin
Michel married Rosalie Laroque. Let me know if anything connects. I am ready to give up!
