Dad was finally able to delve into some of Granddad's photos (after 20 years). Unfortunately, the people that could identify the people in the photos are deceased. I did notice that several of the photos were stamped by a traveling photographer. What time period was this common? The family lived in southern Illinois near St. Louis. What is the likelyhood that one of these photos could be taken in the late 1850s before 1862?
