Online research of county cemeteries is available on the Fairfax County Library website

Examples:  

1. Orrison Slave Cemetery is reported in a backyard of a home on Permit Ct., Kingston Chase Subdivision, about 200 ft west of the Orrison Family Cemetery in Herndon.  Dranesville District.      
2. In the Annandale area, there are reported to be slave cemeteries associated with Ossian Hall and Oak Hill.  The slave cemeteries are Robertson Family on Glen Park Road, Stuart, Custis Family on Royston Road and Unknown Name on Hogan Lake Place. 

Researching cemeteries/burial grounds  

When researching for burial grounds of the enslaved in Fairfax County, one may use this website. https://www.fairfaxcounty.gov/library_cemeteries/   One can search by a person’s name or name of a cemetery. One may add a search filter by type: slave, Black, unmarked, unnamed, “colored, or “Negro.”  

There are challenges when trying to locate the burial grounds: In doing research of land deeds, one finds that there are no descriptions of burial grounds included in the deed. Also, when persons visit the property, they find no visible physical evidence of a burial ground.   

In the past when surveys were completed by visiting each cemetery/burial ground, the location of the cemetery had no address, so the address of the home nearest to the cemetery/burial ground might be included with the description.
