Hi James,
The best person to contact about Michigan photographers is Dave Tinder. He's about to publish a directory of early Michigan photographers.

I can't find his e-mail address, but you might contact the Michigan Photographic Historical Society at
secretary@miphs.org to see if they have it.
Based on the style, I date your image at ca. 1875-1880. The George Eastman House database lists Ives as working from the 1870s-1890s.
