NOT A Happy Camper!

Mrs. Dewey, Harris Ferry, West Virginia 
Darn these photos!
I have pictures of a Mr., Mrs., Coleman and W.M. Dewey. All were labeled Harris Ferry, West Virginia. I have no idea who these people are.
Coleman, being an uncommon name, was the moniker I chose to begin the search. Would you believe it- there were two Coleman Deweys to be found in Harris Ferry in the same general time period!
From what I've read, the process of photography (in those bygone days) required one to sit, perfectly still, for a long period of time. Therefore one rarely sees a smiling portrait. A smile can falter during this long procedure, therefore the subjects were directed to keep a straight face.
When I spend a great deal of time trying to research these photos, I imagine, should I look into a mirror, this is the same expression on my own face. I too am not a happy camper!
