I've found two documents on this, one from 1840 and the other from 1845. The one from 1840 was found on AFRIGENEAS.COM in their slave research forum. I was told about it by Pauleta Davies, a Payne descendant and contributor here. The 1845 document is found in the book "No Land Only Slaves" Vol 3-Caddo Parish by Smith & Lehman.
