Dear Ms. Ramirez,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located a series titled the Coastwise Slave Manifests, 1801 - 1860 for Mobile, Alabama and a series titled Correspondence Regarding Legal Matters, 1826 - 1906 for the Bureau of Customs in Mobile, Alabama in the Records of the U.S. Customs Service (Record Group 36) that may include the information that you seek. Some of these records have been digitized. For access to the non-digitized records, please contact the National Archives at Atlanta (RE-AT) via email at email@example.com.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RE-AT. We apologize for this inconvenience and appreciate your understanding and patience.
In addition, we suggest that you contact the Alabama Department of Archives and History to search for information on a specific slave trader/shipper. They may have collections that include the information you seek. In addition, the Library of Congress has an online exhibit called the African-American Mosaic, which has photographs and slave narratives of former slaves in Alabama that may be helpful. We also suggest that you review the National Archives African American Research website, the FamilySearch research wiki on African American Resources for Alabama as well as the document Federal Records that Help Identify Former Slaves and Slave Owners.
We hope this is helpful. Best of luck with your research!
