It is generally believed that the growing village was named by the provincial governor Don Francisco Cuervo y Valdes in honor of Don Francisco Fernández de la Cueva, viceroy of New Spain from 1653 to 1660. One of de la Cueva's aristocratic titles was Duke of Alburquerque, referring to the Spanish town of Alburquerque.
