I can't remember if I responded to you or not, it has been a long time. I am the youngest daughter of the late Marie Terroux-Masse. My mother married Denis Joseph Masse in Montreal in 1951 and died in 1997 in Ottawa.
I have a number of papers on my grand-father, Georges Terroux, and have managed to trace the Terroux line back to Scotland and France.
Don't hesitate to let me know if you would like more information.
