was the wife of Antonio Pérez, Secretary of State of Philip II of Spain, famous for having helped her husband escape from prison.
Her husband was revealed to be a womanizer; some authors claim that he had sex with the Princess of Eboli, the king's favorite, who put him in jail.
[citation needed] Juana visited her husband in prison and gave him her clothes, thus facilitating his escape.
When Juana moved from Aldea Gallega to Lisbon, she was seized and imprisoned again in the public jail of Madrid, together with her seven children.
Others say that in 1613 she sought the rehabilitation of their children, to which the Inquisition of Zaragoza agreed two years later.
