Dear Ms. Cavanaugh,
Thank you for posting your request on History Hub!
Since the document has been digitized and is available on Ancestry, you may be able to undertake some tagging or transcription work on their website that would help others locate the document in their own searches.
Next, we suggest that you contact the institution that has custody of the original document (this information should be listed in Ancestry). They may have more information about the document availability to other researchers or they may be able to direct you to other projects or organizations that are helping make information related to enslaved people more accessible to genealogists and other researchers.
Finally, there may be projects related to learning and sharing the names of enslaved persons in the area where your ancestor lived that might be interested in learning about the document you located on Ancestry. Many states and other localities are involved in projects like Recall Their Names: The Personal Identity of Enslaved South Carolinians | Charleston County Public Library; Records of Enslaved People | State Library of North Carolina; Names Index for Enslaved Persons | City University of New York (CUNY); or the Index of Enslaved Individuals - White House Historical Association. We suggest that you contact organizations or institutions in the region where your ancestor lived for more information.
We hope this is helpful.
