Found Nancy Barnett teaching in two places. Hazlet in 1928. http://www.ourroots.ca/e/toc.aspx?id=3110
She is listed on page 389 and page 412 mentions she was a widow with a little boy. This is a direct link to the page in the Bengough book. http://www.ourroots.ca/e/page.aspx?id=2873243
I also suggest clicking on EDIT in your post and put some info in the heading instead of just Query, similar to what I did, as it catches attention of volunteers. (we enjoy helping). Butch.
