Thompson of Ontario Canada

I don't have a lot of information about my roots THOMPSON, but i do know some of them lived in the Renfrew area in Ontario, Canada. My great grandfathers name was(i believe)was George THOMPSON not sure who he was married to. He had a son Wilson John THOMPSON who married Hazel Irene LINDSAY who was a school teacher. My fathers name was Earl Wilson THOMPSON who married Eileen Bertha Tompkins. Any information would be appreciated.
