Where is Brandywine, Mississippi located?

Thank you. But I wonder where there homes in 1870? The website stated there were businesses in 1830- 1839 in that area. Where you able to find anything after 1830-1839 in that area?

The link that Mr. Weintraub provided has that Brandywine was "about twenty miles southeast of Port Gibson." That should provide an overall idea of where it was.

Here's a resource you can try:

The Mississippi Department of Archives and History has a listing of old Claiborne County maps (with links to them): https://da.mdah.ms.gov/mapindex/index.php?localaction=browse&keyword=claiborne%20county&order=desc&sort=situationdate
