Since many of your ancestors were originally in LaSalle County, here is a link to American Memories which has old photos of different areas in LaSalle County. This is the link page to the State of Illinois in case you are researching different counties. Unfortunately, there are no photos for Grundy County, but you may find something of use to your research: http://rs6.loc.gov/ammem/fsahtml/fsaPlaces05.html Deb Grundy County IL Coordinator
