Dear Ms. Coleman,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located 18 series in the Records of the Bureau of Refugees, Freedmen, and Abandoned Lands (Record Group 105) that pertain to Mississippi plantations. Some of these records may have been digitized and available using the Catalog. For more information about the non-digitized records, please contact the National Archives at Washington, DC - Textual Reference (RDT1) via email at firstname.lastname@example.org.
We also located the Population Schedules for the 1850 Census and the Population Schedules for the 1860 Census in the Records of the Bureau of the Census (Record Group 29) that contain information about enslaved people in Mississippi. For more information about the non-digitized schedules, please contact the RDT1. During the data collection for the 1850 and 1860 census, two questionnaires were compiled - one for free inhabitants and one for enslaved people. For more information, please see the Questionnaire & Instructions for the 1850 and 1860 census.
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 RDT1. We apologize for this inconvenience and appreciate your understanding and patience.
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?.
A book titled Records of the Ante-Bellum Southern Plantations may be useful in your search. This is a microfilm set of manuscripts dealing primarily with the pre-1865 period from several repositories throughout the south. The accompanying book titled Index to Records of Ante-Bellum Southern Plantations by Jean L. Cooper, indexed deeds, wills, estate papers, genealogies, personal and business correspondence, account books, slave lists, and many other types of records. Both of these are microfilmed and are available for viewing at the Library of Congress and many other institutions.
Additionally, using the enslaved people questionnaire of the 1860 US Census Schedules, RootsWeb and Ancestry.com put together this incomplete listing for Lowndes County, MS. FamilySearch provides a resource for the Enslaved people register and owner ledger (Lowndes County, Mississippi), 1837-1846 that may be useful. Another source of information is the Lowndes County Local History Indexes.
We hope this is helpful. Best of luck with your research!
