    Historical county boundaries will draw, and an information pane about the county of interest will appear at the bottom of the map.

The latitude and longitude for the blue dot is also displayed.**
  3. Check the “Show historical county labels” checkbox in the lower left corner of the map to see the names of the historical counties on the map
  4. Optionally, check the “Show county chronology if this place…” checkbox in the lower left corner of the map to see a complete listing of every county boundary change for your chosen location from the date you typed back in time to original county formation
  5. Optionally, check the “Also show present-day county lines” checkbox in the lower left corner of the map to see present-day county lines (thin red lines) overlaid on top of historical county lines (thicker brown lines)
  6. Optionally, check the “Also show US townships” checkbox in the lower left corner of the map to see present-day township boundaries (thin dark orange lines)
  7. Click the button in the upper right corner of the map to use your current location. Click the button again to automatically update your location every 1, 5 or 10 minutes (Monthly Contributors also get an option to update every several seconds).***

While some other tools can show the Newberry Atlas in GIS formats for Google Earth, requiring downloads and installation, this free tool shows the entire Newberry Atlas of Historical County Boundaries overlaid on Google Maps in a web browser.

Coverage Notes

– Coverage includes all 50 US states, from as early as 3/4/1629 through 12/31/2000. For present-day county lines use the County Lines on Google Maps tool.

Other Notes

  • The Search places box uses a standard Google Maps geocoding engine, therefore you can type PRESENT-day street addresses, road names, points of interest, and GPS coordinates (see * above) to see what county that location is part of
  • NEW! Some counties or regions were claimed by more than one jurisdiction in some historic years. When this is the case, an “Overlapping jurisdiction” button will appear at the bottom of the map enabling you to toggle to the other jurisdiction’s information.
  • The map layers from which this information is extracted are very large, so it may take several seconds to finish drawing
  • Note that typing an address will zoom in the map very close, whereas typing a city or county by itself will show you a map with a wider view
  • Disclaimer: While the number of decimals in the latitude and longitude displayed for the map marker imply a positional accuracy of within a few feet, note that Google Maps is not inherently that accurate, and therefore this tool should not be used for legal purposes or anything beyond entertainment value.
