Bonanada was the midwife of the royal family of Aragon.
She was evidently a trusted and reputed midwife, as she was recommended among the members of the royal family: she participated in the labor of Eleanor of Aragon, Queen of Castile as well as Violant of Bar, and was described by Peter IV of Aragon and Eleanor of Sicily as an excellent servant worthy of complete trust.
In 1373, she was accused by the heir to the throne, the future John I of Aragon, of the murder of Joan of France by use of sorcery.
