1860 US Census, Franklin County, North Eastern Division, Virginia. Note: Sally Dunning was living with her mother Mildred, grandmother Hannah, aunt Mary, older brothers Adam and John, younger brother George, and sisters Jane, Lucetta and Mildred, all free mulattoes. Given the three generations of free women of color, that line was likely free since the colonial period.
