Is this online somewhere for searching? Stopping at 1866 would mean that any enslaved artisans in 1860 or earlier would not have been viewed on the censuses. For example, my great-grandfather, Edmond Simpkins (b. ca 1838 SC) was listed as a blacksmith and a farmer on the 1880 census. He had been enslaved under James Edward Calhoun on the Millwood Plantation in Calhoun Falls, Abbeville Co, SC. Sonia
