Hello I'm trying to find out some info on the "Perus" spelling somewhere about the time of my great grandfather the spelling change from Perus to Pierce. I know they came from Canada and when they did the spelling of the name change. They settled in Wis, LaCrosse area My fathers name is Thomas Pierce, his father was Charles Pierce married to Josephine Bahr. That is as much that I have. Timothy Pierce [email protected]
