By the late 1840's the acre graveyard surrounding the Free Church had become crowded. On 24 February, 1849, seventeen citizens of Loudoun County, headed by Humphrey Brooke Powell, incorporated as the Sharon Cemetery Company. In November, 1850, they purchased four and 1/2 acres from Marietta F. Powell for $520, with the deed noting that the Free Church and its graveyard were now owned by the new company. The circle with CSA in the center is a memorial grave for Confederate soldiers. The church was used as a hospital during the war, and soldiers who died in the hospital were probably buried in random graves throughout the cemetery. The United Daughters of the Confederacy erected the monument, in the center of the circle, with eighty markers of unknown burials. In areas where graves were found outside of the mapped sites, they have been identified using the closest lot number and the "A" indicator.
