According to Madison's 1873 memoir, his older brother Beverley and his older sister Harriet moved to Washington D.C. in 1822 when they "ran away" from Monticello. Jefferson ensured that Harriet was given money for her journey. Because of their light skin and appearance (they were 7/8 European or octoroon), both identified with the white community after their moves and probably changed their names. Hemings said they had married white spouses of good circumstances, and moved into white society. They apparently kept their paternity a secret, as it would have revealed their origins as slaves, and disappeared into history.
