QUICK TIPS FOR USING THIS TOOL:2. Once you see county boundaries, click inside any county to see its name and details. The information window that appears lists the county name and when that county's then-current boundaries (as of the year you typed) went into effect. Click the < and > buttons next to the Year input box to go back and forward a decade at a time.

OTHER NOTES:
* The Place box uses a standard Google Maps geocoding engine, therefore you can type present-day street addresses, road names, points of interest, and the like, and then type in the correct historical year to see what county that address or road was located in back then (e.g. type "Silver Oaks Cemetery, Tyner, TN" or "Old Lee Highway, Tyner, TN" together with the year 1880). Of course, this doesn't account for addresses or road names that may have changed, so if you suspect that, then just start with the right present-day town or city name.
- This tool works best with Chrome, Firefox, Safari (including iPad), and many other browsers; there are some performance issues with Internet Explorer. For some mobile browsers, click the "View web version" link at the bottom of this page on the mobile browser.
- Occasionally, county lines may take up to 10 seconds to appear; if the county lines never appear, try refreshing the page (F5) and try your search again.
- This tool uses an experimental Google Maps API feature called Fusion Table Layers. The underlying county boundary map files used are quite large, and Google Fusion Tables are themselves a beta product. As with any new and innovative technology, don't be surprised if things occasionally don't function as expected.
- Currently, county boundaries must be viewed one state at a time.
