I am looking for information on Jean Marie Cartes born in the Basque region of France. He came to Natchitoches, Louisiana from Nacodoches, Texas by way of the El Camino Real delivering goods to the riverboats on the Cane River. He would pass through the Neutral Strip of Louisiana & Texas. He married into the Rouquier family. His son Francois had a case that went all the way to the Louisiana Supreme Court. I am interested in Jean Marie's background in Basque, France.
