We have resolved the mystery and now know the names of everyone in the photo. Note the image now with the updated name caption.
This is a photo of the 1958 Peterborough UE Juvenile Lacrosse Team.
We would appreciate hearing from anyone who can help us identify the gentleman in the back row on the left (circled in yellow). You can contact us via e-mail at firstname.lastname@example.org noting “To the attention of Pete” in your subject line, or phone us at the Hall of Fame at (705)743-6897.
