William Maddox, a stonemason, worked for Jefferson in 1802 and again from 1806 to 1808. In 1802, Maddox worked with stonemason Joseph Morin on the dependencies and a stone nailery likely located on the mountaintop. Jefferson noted in September that he "Settled with …Wm. Mattox for the stone work of the offices & the Nail house." When Maddox returned to Monticello in 1806, he worked mainly on the Shadwell mills and the stone stable at the eastern end of Mulberry Row. Overseer Edmund Bacon apparently had difficulty with Maddox, reporting to Jefferson that "I never could get Maddox to set in about the job … untill now." Though Maddox began working on “the stone stable,” Bacon wrote to Jefferson before the building was finished, telling him that "Maddox is gone from home and will not be back for some time." Jefferson likely hired another tradesman to finish the stable.
