If you are searching for information on the various plantations that were in the Carroll Parish area before the Emancipation Proclamation, I have posted all the information I have gathered over the years to one website.

Most of the information attempts to capture things such as number of slaves owned with names, owners, years of ownership, present day locations, etc.

I hope this helps someone trackdown their ancestors last slaveowner.
