The Benoits are difficult to search for as I am in the same situation. For years I have been trying to find info on Elizabeth Benoit but come up empty constantly. A website to try if you haven’t already is ngb.chebucto.org, since finding it many questions have been answered. There are military records (ww1 & ww2), various census, previous names of towns (very helpful), and many other resources.

If I come across anything relating to the person you are searching I will for sure share it.
Good luck with your search.
