I am from Guelph Ontario Canada.When I posted that information I thought they were going to be books about all the Gauvreaus and it is not.( how I wish they were journals!!LOL)
There are 3 books,but they are surname books.They were published in 1965? and they are from Institut GenealogiqueDrouin.There are a few Gauvreaus in there.I can make out some of the words and I haven't looked at all of the books yet.
These books are my grandfathers and I can borrow them any time. They brought them somewhere a couple of years ago and they were going to be charged about $100 per page to translate them!!
