Dear Ms. Greene,
Thank you for posting your request on History Hub!
As records of enslaved people were often listed as property or estate transactions, we suggest that you search Mississippi Probate Records, 1781-1930, and request a search from the Mississippi Department of Archives & History or the Jefferson and Franklin County Clerk of Court. We also suggest that you search the Jefferson County Mississippi 1860 slaveholders and 1870 African Americans and the Slave Data Collection for mention of the Camerons.
We also suggest that you review the National Archives African American Heritage web site, the FamilySearch Research wiki on African American Resources for Mississippi 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!
