Dear Ms. Okoye,
Thank you for posting your request on History Hub!
Most of the removal records located at the National Archives, such as the emigration rolls and the lists of those who stayed behind, can be found on various microfilm publications. Typically, only the head of the houseland is listed with others in the family and slaves only numbered/counted.
Following the relocation and subsequent resettling by the Bureau of Indian Affairs (BIA), the tribes fought the inclusion of the freedmen within their numbers. Therefore, the earliest efforts to list them by name was only started by the BIA in the 1880’s onward when the General Allotment Act was passed and the Dawes Commission would shortly follow.
We suggest that you contact the National Archives at Washington, DC - Textual Reference (RDT1) via email at firstname.lastname@example.org and ask them to assist you with locating possible records about slaves during the Trail of Tears in the Records of the Bureau of Indian Affairs (Record Group 75).
We hope this is helpful. Best of luck with your research!
