Dear Ms. Brockenborough,
Thank you for posting your request on History Hub!
For an overview on how to begin your research, we suggest that you review NARA’s Resources for Genealogists as well as the FamilySearch Research wiki for North Carolina Genealogy and Pennsylvania Genealogy, the FamilySearch research wiki on African American Genealogy. In addition, the document Suggestions and Advice for Family History Researchers and the National Archives African American Research website may be useful.
We hope this is helpful. Best of luck with your family research!
