Washington businessman Louis H. Bell owned Forest Lawn Cemetery on Sheriff Road in Landover, Maryland. Bell also owned Prince George's Nurseries, and planned to add an additional of nursery land to the cemetery. In nearby Washington, D.C.,
Columbian Harmony Cemetery had met its capacity. Established in 1859 by a
burial society for free Blacks, it was the most active cemetery for Black residents from the 1880s to the 1920s. But by 1950 the cemetery ran out of room and stopped new burials. The lack of burials and a perpetual care endowment left the cemetery $3,000 in debt every year by 1956. In 1957, Bell, who wished to develop the Columbian site as real estate, offered the owners of Columbian Harmony Cemetery a 25 percent stake in the new cemetery and offered to pay all relocation costs in exchange for the cemetery's property in D.C. Although Columbian Harmony rejected this offer, negotiations continued. Bell eventually agreed to also establish a perpetual care fund, designate a section of the cemetery as the "Harmony Section", and allowed the Columbian Harmony Cemetery's board to appoint half the members of the new board of directors of the new cemetery association. Beginning in May 1960, approximately 37,000 graves were moved to National Harmony Memorial Park. The District of Columbia Department of Health had to draft and win approval of a whole new set of regulations to govern the relocations. A D.C. district court agreed to issue a single exhumation order, than review thousands of cases. All the heirs of those buried at Columbia Harmony Cemetery were contacted and their permission to move the graves secured. More than 100 workers exhumed, recrated in new coffins, moved, and reburied the dead. However, there were hundreds of graves moved every day; although it is seldom mentioned, many were just put in an unmarked mass site. The re-interments were completed on November 17, 1960. It was the largest cemetery move in the nation's capital, and cost $1 million. Unfortunately, the relocation agreement did not cover the existing memorials and monuments, which would have required identifying remains, moving the markers, and burying each body with its corresponding marker, if any. This would have taken much more time. According to the
Maryland Historical Trust, none of the original grave markers were retained. In 1966, about 2,000 graves were transferred from Payne's Cemetery to National Harmony Memorial Park.
Payne's Cemetery, located at 4640 Benning Road SE, was a historic cemetery founded in 1851, when most cemeteries in the city were segregated. It was exclusively for African Americans. Payne's Cemetery was declared abandoned by the city in the summer of 1966, and the graves moved by September 1967. Stewart Enterprises, a company based in
New Orleans, Louisiana, purchased National Harmony Memorial Park in 1998. Stewart Enterprises agreed to retain most of the 1959 agreement with Columbian Harmony Cemetery, although Columbian Harmony was no longer permitted to name members to the cemetery's board of directors. ==Notable interments==
