Sally Hemings had at least six children whose births were recorded. Some sources, including Madison Hemings's memoir, says that Sally Hemings conceived her first child while in Paris with Jefferson, but that the baby died shortly after birth. Another daughter named Harriet, whose birth was recorded at the time, also died shortly after birth, but four other children lived to adulthood, three boys and one girl: Beverly, Harriet (the second daughter given this name), Madison, and Eston. Beverly and Harriet left Monticello to go North when they were both around twenty-one years of age, but Madison and Eston were freed by Jefferson's will after he died. Although Jefferson did not legally manumit Beverly and Harriet, he secretly arranged and paid for Harriet's transportation to Philadelphia, using his overseer Edmund Bacon as an intermediary. Although he marked in his Farm Book that both had "run away," Jefferson never made any attempt to re-enslave them. Gordon-Reed noted that this Hemings family was the only one in which all the children were freed, and Harriet the only enslaved woman he freed. She suggests this special treatment was significant and related to their status as his "natural" children.
