I learned today from Patti Rockey of the Williams County Recorder's Office that their WPA Cemetery Plat Maps are now all posted on their website!
The maps are arranged alphabetically by township name with cemetery names listed alphabetically within each township.
A real bonus for a researcher, is the additional historical information that details the entire history of the WPA program (Works Progress Administration / Works Projects Administration).
Many younger folks, in particular, may not be well versed in this important part of American history and its direct impact on those who were out of work during the long years that were known as The Great Depression.
