Commandant Claude Charles du Tisné had arrived to the outpost just a few years earlier to convert the 2 huts built in 1714 by Louis Juchereau de St. Denis into a fortified post on Red River of the South to establish France's claims to the region and to prevent the Spanish forces in the province of Texas from advancing across the border.
Brevelle traveled and mapped the areas along the Red, Sabine, and Trinity Rivers where he lived among and traded with the Natchitoches, Adai, Hasinai, Nasoni, Yatasi, Tawakoni and Kadohadacho Indians.
[5][6] Brevelle took a young Native American slave from the Village of the Adays near the El Camino Real (English: The King’s Highway).
Brevelle so loved Anne that he obtained permission from Fort Commandant Louis Juchereau de St. Denis to marry her and free her from slavery.
In Louisiana, the term Creole is defined as native-born people of ethnic European background mixed with Native American and/or African.
