I have a book on it somewhere....OLD SOUTH BOOKS
any info positive about slaveowners today is a mite limited on the left managed internet
I think William maybe...he made the barrels..
but Robert Dunbar had more properties maybe...not sure
My greatX4 grandpa took his cattle from Leaf river basin to him in natchez and fetched his second (bigamist) wife from Dunbar...legend had it that her mother had been a mistress and servant to one of the male Dunbars
If you track it down, let me know. I’d love to have that information and my daddy would too.
