Gleanings from old records indicate that Chataignier's first settler was Ursiana Manuel who came from Mexico via New Orleans circa 1793 when Louisiana was a Spanish colony and George Washington was serving as President of the new republic known as the United States of America. The descendants of Ursiana Manuel are still living on the original land grant obtained by him during the Spanish domination of Louisiana. Other early settlers mentioned are Jacques Fontenot, Louis Redan, General Garis de Flaugeac, Artemon Lafleur, and Valentine Savoy. Savoy, incidentally, was the first man to begin the manufacture of spinning wheels in this part of the country.
