The translated phrase is “Les Naturels ou indigènes font ceux qui font nés dans le pays de Parens Citoyens.” The often cited NBC translation was “The natives, or natural-born citizens, are those born in the country, of parents who are citizens”. It came in the 1797 translation. Previous translations used “The natives, or indigenes...”
Indigene is used in English, and is NOT the same as natural born citizen.
