Search for the name you see Buteau is hard to find because it is very bad written. The little that I have found is buteau, Beteau, Burteau, Butean etc.
I should just find the parents of William, husband of Adele. I have several websites where you have access to death but it is often after 1937 and I know he died before 1930.
