Marie des Nieges Juchereau de St. Denis was the daughter of Chevalier Louis Antoine Juchereau de St. Denis and Emmanuella Maria Stephania Sánchez Navarro y Gomes Mascorro. She was born on August 5, 1734 in Natchitoches, Louisiana. She was baptized there on August 16, 1734. Her godparents were Francois Godeau, a surgeon, and Marie Petrone de St.Denys.
She died in in Bayou Chicot, Pine Priarie, Opelousas, Louisiana. She was buried on August 10, 1797 in Opelousas, Louisiana [Southwest Louisiana Record V1A, Page: p. 222, "Marie St. Denis"].
Her name has been written various ways including: Marie Des Nieges St. Denis, Marie Des Neiges De St. Denis.
She witnessed the baptisms of Jacques Maurice DeBlanc in Natchitoches, Louisiana in 1756 and Antoine Mariè de Mézières on January 21, 1762 in Natchitoches, Louisiana [ibid (Church Abstracts), Vol. II, p 58,99,468,802].
On April 25, 1758, Marie de Soto inherited the slave 'Marguerite dite Yancdose' from her father's estate. She also inherited an 8 day old orphan.
In 1767, Pierre Metoyer began a union with the slave Marie Therese whom he leased from Marie de Soto. In 1788, Pierre bought Marie Therese and their infant son outright from Marie de Soto.
In 1780, the heirs of the Fazende family sued Marie for and won the ownership of a young male slave that Marie was in possession of, and whom she had emancipated. As late as April 4, 1783, Marie was still refusing to turn over the boy. By the 1785 census however, the boy is not listed in the de Soto's household.
Marie was an independant woman for her time, probably due to her husband's incarceration. Even though women rarely owned property during this period in Louisiana, Marie requested and received several grants of land.
