Don't know where to look for this information, maybe in old city directories? I have several very old photos of children that are unidentified. Many are marked with the photography studio's name and location. I would love to find out when the studios were in business to maybe pinpoint what generation(s) of my family tree these might connect to. (Though some probably could, I can't tell by the clothing style.)

If anyone's curious, the studios are: Finzel in Weston, Dubbs in Weston, and Zimmerman in Carey (though that last one is Hancock Co, I think).

Thanks for any help you can provide.
