Sources of information are the D.A.R. Readings in the 1940's and the Readings in the 1980's and Flint Hills Genealogical Society Reading in 2010. The D.A.R. put the earliest known reading together and some of the stones they read are now gone, so it was important to use their work along with the current information. Mistakes may have been made, but every effort was made to make out the information on the stones. Not all headstones may be still be standing, as there have been some vandalism and natural forces through the years.
