Edouard Pronovost-1840's-Trois-Riviers&Wisconsin

I'm looking for information on my great-grandfather Edouard Pronovost. He originally lived around St. Prosper de Champlain or Ste. Geneviève-de-Batiscan, possibly born in the 1840's near Trois-Rivières. He eventually moved to Wisconsin ( Sascou?) where he established a second family. I would like to find out where he died and any information about his children in Wisconsin.

Je suis à la recherche de renseignements sur mon arrière grand-père, Edouard Pronovost,né vers 1840, fils de François P. et de Marguerite Vézina, natif de la région de Trois-Rivières, sois de St.Prosper-de-Champlain ou de Ste. Gneviève-de-Batiscan. Il a habité au Wisconsin, probablement durant la période 1885-1895. Si vous avez des informations, s.v.p. contactez-moi.
