INSTRUCTIONS:
1. Install the Historical U.S. Counties Auto-Checker Chrome extension by clicking the \"Add to Chrome\" button in the upper right corner of this page.
2. Go to any search form on Ancestry.com or FamilySearch.org and start typing a place and a year. As you finish typing in each box, the Historical U.S. Counties Auto-Checker Chrome extension will update information in a box as shown in the screenshots. Note that the information shown is updated based on the last year box and place box you were interacting with.
3. Read the Note and Warning messages that appear about some counties, and click the MAP link to view historical county boundaries for the place/county/state and historical year you are researching. The Auto-Checker first tries to center the map on the city/place/township you are searching for, and if it cannot find an exact match, it centers on the county you are searching for, and as a final fallback centers on the state you are searching for.
4. Using the map, when you find the correct county name for the year you are researching, put that county name in the place search box on Ancestry or FamilySearch in the form \"City, County, State, USA\"
ENABLE TREE FACT-CHECKING & LIFEMAP FUNCTIONALITY: If you are a randymajors.org Research Hub Monthly Contributor, the Auto-Checker will also check all U.S. location facts on Person profile pages on Ancestry trees, plus create a link to an interactive LifeMap for each ancestor!

That's all there is to it. Hope the tool helps you discover some \"hidden\" records!
(When you install the Auto-Checker, you may see a standard confirmation window that states that the extension can “Read and change your data on www.ancestry.com or www.familysearch.org or www.google-analytics.com”. Rest assured that the Historical U.S. Counties Auto-Checker Chrome extension ONLY reads the place and year fields and shows the county information as shown in the screenshots above; it absolutely DOES NOT make any changes to your data whatsoever. No logins or email addresses are required to use the extension!)
