George C. Willick (1937-2014), the previous Pettis County MOGenWeb Coordinator, did a massive amount of work on the Pettis County cemeteries. His notes are retained and marked as "GCW".
With few exceptions, the photographs for these cemeteries were submitted by Justin Watkins, as well as most of the updates. Andrea Grupe also provided several hundred photographs.
Where possible, the pictures are numbered in the order they were taken.
