Fire insurance maps may provide you with a different view of where your ancestor lived. Insurance maps are generally available between the late 19th and early 20th century centuries. They may tell you what type of home your ancestor lived in, what it was made how, how many stories it was, etc. The maps showing neighboring homes also gives an idea of the “feel” of the neighborhood. Maps are available for urban areas and small towns as well. The Library of Congress website has more information at http://www.loc.gov/exhibits/treasures/trr016.html and searches at Worldcat http://www.worldcat.org/ for “sanborn map yourtown” may locate some references as well.
