Elizabeth Hemings's second daughter Betty Brown (1759-after 1831) was the first of her family to come to Monticello, as personal servant to Jefferson's wife Martha. After almost sixty years of work in the main house, she was one of the last of the Hemingses to live on the Monticello mountaintop. She had two sons, Wormley Hughes and Burwell Colbert. Wormley Hughes (1781-1858) was head gardener as well as a wagoner and coachman, with charge of the Monticello stables.
The claim that Thomas Jefferson fathered children with Sally Hemings, a slave at Monticello, entered the public arena during Jefferson's first term as president, and it has remained a subject of discussion and disagreement for two centuries.
