multiple generations repeating the pattern. The large Hemings family, with Betty Hemings as matriarch, was at the top of the slave hierarchy at Monticello; its members working as domestic servants, chefs, craftsmen and artisans. Sally Hemings had light duties, and as children, Eston and his siblings "were permitted to stay about the 'great house', and only required to do such light work as going on errands." Like their older brother Beverley, at age 14 Madison and Eston each began training in carpentry, under tutelage of their uncle John Hemmings, the master woodworker at Monticello. All three brothers learned to play the violin (Jefferson also is known to have regularly played when he was younger, and his younger brother Randolph, according to the ex-slave Isaac Granger, "used to come out among black people, play the fiddle & dance half the night".) Madison and Eston were freed in 1827, in accordance with President Jefferson's will. (Madison was 22; Eston was freed at 19.) Additionally, Jefferson's will petitioned the legislature to allow the Hemingses to stay in Virginia after being freed, unlike most freed slaves. In his 1873 memoir, Madison said the Hemings children were freed as a result of a promise Jefferson made to Sally Hemings. After Jefferson's death, Sally Hemings was "given her time" by his daughter. The older woman lived freely with her two sons in Charlottesville. In the 1830 census, the census taker in Charlottesville classified all three Hemings as white, showing how others perceived them by appearance because of their overwhelming European ancestry. Sally was of three-quarters white ancestry. Her children were seven-eighths white and thus legally white under the Virginia law of the time. It was not until 1924 that Virginia passed the Racial Integrity Act, which classified anyone as black who had any known African ancestry, under the "one drop rule". Post-slavery life Upon gaining freedom, Hemings initially pursued a career in woodworking and carpentry in Charlottesville, Virginia. In 1830, Eston Hemings purchased property and built a house on Main Street, where his mother lived with him until her death in 1835. Marriage and family In 1832, Eston married a free woman of color, Julia Ann Isaacs (1814–1889). She was the daughter of the successful Jewish merchant David Isaacs, from Germany, and Nancy West, a free woman of mixed race. Nancy West was the daughter of Priscilla, a former slave, and Thomas West, her white master.
