I found this site and have utilized several maps dating back to 1861 for Knox County Illinois..a fantastic resource!! Just pick out your county in the alphabet list above and it will open a list of all available maps.

You let the secret out. That is the site I mainly use, but there are many more out there.

Sorry!! I live in an area that dates back to early 1800's, and my home is still part of a log cabin from?? So far we have found an 1889 IH,1924 Buffalo, some wheats and a lot of old cast iron pieces. Unfortunately, I live just inside city limits and the plat maps don't show my home or a couple others that supposedly date back to that time period. It is fascinating to see the number of old home sites that are within a short distance of me that disappeared in the early and mid 1900's..target sites if I can locate them out in the timber!!!!

Thread bump....maybe not too late to help OP


Ever try the Illinois Clearinghouse site?? The entire state was photographed from above...it's too bad that the photographs were taken from that high of an altitude. Detail is not the best, but it sure helps researching.

Click on "Viewer". The map will appear and every red square on the map is a photo link for that area. the "TIF" option will allow zooming in closely. While the "JPEG" can only zoom in or out.



Here is Knoxville in 1940...
