I would seek out facebook pages for the specific areas and towns you think the photos were taken. I live in Boston and just about every neighborhood has its own facebook page, where current and former residents can "remember when". Many members of these pages are "old timers" who have moved out to area and may be able to place a name with the face. I had success doing this. I found out the names of a photo taken of my father and his friends in 1943. I know have the names of all his floor hockey team.
