Dear Mr. Tyler,
Thank you for posting your request on History Hub!
We suggest that you review NARA’s African American Heritage website, especially the Archives Resources section, the Subject Portal, and the African American Records: Freedmen's Bureau web pages as well as NARA’s Rediscovering Black History blog and the History Hub response to How do I search for my family’s history?.
We also suggest that you contact the North Carolina State Archives and the Indiana State Archives for any information or resources in their holdings pertaining to freed blacks or African American research. In addition, you may wish to search the FamilySearch wiki Greene County, North Carolina Genealogy and the Richmond County, NC Historical Society for additional research tips.
We hope this is helpful. Best of luck with your family research!
