I don't know anything of this family, other than in the late 1800's there was a Schellhous photographer in Grand Rapids, MI.
I rescue old photos from antique shops and happened on one taken by this person. Also, I found one taken by a Thoms Photography studio, from Grand Rapids. I did coorespond with a person, who descended from one of these lines, and it turned out, that a Schellhous married a Thoms.
Does anyone have information on this? I believe, if you'd like to see the type of photos they took, with their "by line" at the bottom, I have a file that I can send for you to look at.
