I am looking for someone who may have access to info on when the following photographer Studios were in bussiness. I am thinking maybe around 1924 or so?
J. O. Oleson DeKalb IL
New Ground Floor Studio DeKalb IL
Rowley DeKalb IL
W. E. Bain DeKalb IL

Carlson Sycamore IL
De L. Sackett Sycamore IL

I have old family photos that I beleive are of the Lovell family. I am hoping if I can get info on the studios I can put them together with dates of the families,
