Cemeteries need caches! This one had a cache until it was recently archived by the CO. You're looking for a camouflaged lock-n-fock container.
I couldn't find any information online about the history of Magnolia Cemetery, however it dates at least to the earliest years of the 20th century. The earliest date of death on a marked grave is that of Mary Belle Hilliard, who died on September 24, 1906.
