Sally Miller, born Salomé Müller (c. 1814 – ?),[1][2] was an American woman enslaved sometime in the late 1810s, whose freedom suit in Louisiana was based on her claimed status as a free German immigrant and indentured servant born to non-enslaved parents. The case attracted wide attention and publicity because of the issue of "white" slavery. In Sally Miller v. Louis Belmonti (1845 La), the Louisiana Supreme Court ruled in her favor, and Miller gained freedom.
Despite the doctrine of partus sequitur ventrum incorporated into state law, by which children followed the legal status of their mother at the time of birth, Miller was not successful in her attempt to gain freedom from slavery for her three surviving children. In a case settled in her favor by the judge, she won a case in which her former master John Fitz Miller tried to clear his name by proving that she was part-black and had been born into slavery in Miller v. Miller (1849 La). His appeal to the State Supreme Court was dismissed. Her identity remains controversial.
