Joseph Barker was a general merchant whose store and home was located at Barkers Landing on the St. Jones River in Murkerkill Hundred. Titled by Barker as his “Negro Ledger A”, the volume contains entries for purchases made by his African-American customers. Each entry notes the name of customer, date of purchase, items purchased, cost for each item, date and amount paid, and how paid. Often bills were paid with grain, other items, or labor.
