For this challenge, I chose to look at the Library of Congress' collection. I was less than thrilled with what I was (not) able to find so I went a different route. Many USGenWeb sites have maps or links to maps for areas in their respective counties. I am consistently blown away by how wonderful the Isabella Co., Michigan USGenWeb site is. It is the type of GenWeb site all others should aspire to and in all my years of using the GenWeb network, I have yet to find another county site that compares. So obviously, Isabella's site was the first I went to to find maps and I wasn't disappointed.
