I found much more on her family line...
"Madisonville was founded by Jean Baptiste Baham in 1800 as the town of Cocquille or Cokie because of the abundance of shells in the area, at the site of the Native American village of Chiconcte. In 1810 it was renamed in honor of President of the United States James Madison."
Jean Baptiste Baham married Francoise Guillory and had the following Jean Baptiste Baham:
"Jean Baptiste BAHAM had no record of a marriage. He willed his estate to his brother, Joseph although he had a relationship with Marianne RABY, a free woman of color, which produced children.
(1) Josephina Evelina BAHAM, born 18 January 1812, widow living in Livingston Parish, Louisiana in 1862 (baptismal sponsor Clarisa RABY)
(2) Henrieta Emelia BAHAM, born 12 March 1814, if also known as Caroline married Elias DYKES
(3) Juan Bautista BAHAM, 25 February 1816, of Washington Parish, Louisiana in 1862
(4) Pedro (Peter) BAHAM, born 10 October 1818, lived in Texas in 1862
(5) Juana (Anaise) BAHAM, born 24 November 1820, married Robert M. LANIER of St. Tammany Parish, Louisiana
(6) Maria Francisca (Frances) BAHAM, born 10 February 1823., married Benjamin W. LANIER brother of Robert M. LANIER
(7) Antoinio (Raby) BAHAM, born 22 March 1826 probably married an Anna of Calcasieu Parish
Note: Information about children from Sacramental Records and Marianne RABY’S Succession which also mentions Joseph Strong about whom nothing is known except that he was living in Texas at the time of her succession."
Juan Bautista Baham and Sarah Leucy Lindsey were Nancy's parents...
All I know so far...
