This is a Mexican song from 1932 by Lorenzo Barcelata, named after the wife of the president of Mexico from 1928 to 1930, Emilio Portes Gil (best known for standing up to the US and giving asylum to the defeated General Agusto Sandino of Nicaragua). The tune, with both Spanish and English words, became a popular hit in both Mexico and the US, with successful new versions coming out for decades.
