Identified during the 1997 Plantation Archaeological Survey, Site 9 represents another slave quarter that Jefferson failed to identify in any of his writings or plats of the plantation. Domestic artifacts such as creamware, pearlware, wine bottle glass and window glass were recovered in addition to a number of nail rod fragments. At the turn of the ninteenth century, Jefferson began importing nailrod from Philadelphia to supply his nailery on Mulberry Row. It appears that enslaved Africans obtained this material and possibly produced nails in their quarters during their spare time.
