Hello, all - I just stumbled upon photos held in the St. Marys, Ontario. In case this is news to other researchers, here is the info:

The photos have been scanned and are online at:
http://www.stmarysmuseum.ca/
Click on the "Picture St Marys" link on the museum home page.

I was lucky enough to find a photograph of Motherwell, near St. Marys, most likely taken by an ancestor who worked as a professional photographer in St. Mary's in the early 1900s. The area in the photo was near where her parents' farm was located.

Anyway, others may find some "jewels" there too, including photos of ancestors and other kin.
