Siota or Siosta

The mother of Marie Pichot, the wife of Jean Baptiste Gaury, was a former slave named Nanette. She died a few years before her daughter with Jacques Pichot married Jean Baptiste. Her former master, a man with the surname Siota, apparently freed her. Intriguingly, her daughter would later use the surname of Siota. Using ANOM's Leogane parish records, we found that the man who likely owned Nanette died in 1746. He was from the diocese of Comminges in France and went by the name Jean Siosta.

Apparently Jean Siota may have left behind "mixed-race" progeny, too. In 1748, a Marie Francoise Siota died. She was the child of a Bastienne Siota, a free "mulatto woman" and likely the daughter of Jean Siosta. Is it possible Nanette was also the mother of Bastienne Siota? Or was she freed for another reason by Jean Siosta? It would also be great to uncover where Nanette came from and why her daughter later dropped the Pichot surname.
