 When Belgrano was dispatched to Upper Peru, María Josefa followed him to Jujuy. She took part in the Jujuy Exodus and saw the battle of Tucumán. It is thought that she was pregnant by this time. Her son, Pedro Pablo, was born on 30 July 1813. Pedro Pablo was adopted by Encarnación Ezcurra and her husband, Juan Manuel de Rosas, who she had married shortly before.
