At age four, Prieto's family moved to Mexico, where she devoted herself to study. There she learned several languages that allowed her to perform as a translator of notable literary works. Later, she traveled to Guadalajara, Jalisco, where she composed most of her own works. It is known that she collaborated with the Mexico-based French writer on the newspaper "El Federalista". In 1864, before the French Intervention in Mexico, she moved to San Francisco, California. A year later, in 1865, she returned to Mexico and married her cousin Pedro Landázuri Diez, a notable politician of that era, and moved to the Tacubaya neighborhood in Mexico City.
