Within the rough boundaries of this site lie the remains of the slaves and former slaves of the Albert McCoy family. Scant historical documentation prevents any reliable names and dates of burials beyond those mentioned on a memorial marker placed by McCoy descendants in 1928. Rough dates of burials extend from the antebellum era through the post-Emancipation period, from the 1840's to the 1880's, and the cemetery is estimated to contain 25 to 50 plots. The cemetery bears many indicators common to slave cemeteries in the United States, including cultural practices that mix remnants of African traditions with Christian beliefs. Periwinkle was used as ground cover because it was relatively easy to sow and maintain, and permanent grave markers were not typical, so relatives often used fieldstones to designate gravesites. Most slave cemeteries also followed an east-west burial pattern, explained either by burial facing east toward an ancestral homeland or, for Christians, toward the eastern sunrise in preparation for the day of resurrection. Thomas McCoy, son of Albert McCoy and a member of St. Mark's Episcopal Church, established a perpetual trust to the parish in the 1940's for the care and upkeep of this cemetery and the cemetery at St. Mark's, and church members have maintained that bequest since his death.
