The City of Greensboro North Carolina Library has a transcription of records from Union Cemetery in Guilford County, a burial site for many Guilford County African Americans.
“Union Cemetery is one of the most important burial sites for African Americans in Guilford County. Located on the east side of the 900 block of South Elm Street, it has been in use since the 1880s. The following is a list of burials with grave markers (there are many unmarked graves). Where possible, names are correlated with those appearing in the 1887 Greensboro City Directory. (This list was first published in Family Burying Grounds and Abandoned Church Cemeteries in Guilford County, N.C., and Immediate Environs, compiled by O. Norris and Rebecca H. Smith, Guilford County Genealogical Society, 1994.)”
