Annetta Ferri (1457 - 1511) was a Florentine woman who was hired by the House of Auditore as a servant. She was very close with the family, living in the Palazzo Auditore and was treated as a member. Orphaned at a young age, she and her sister Paola went down separate paths but remained close.
In 1476, after Giovanni, Federico and Petruccio were falsely arrested for treason, Ferri assured Ezio that she would take Maria and Claudia to Paola's brothel to hide. Ezio later met with his family after witnessing his family's execution, with Ferri finding Ezio's reaction to the brothel funny.
She later moved with the Auditores to Villa Auditore in Monteriggioni, Tuscany, fleeing in 1500 during the Fall of Monteriggioni by the Borgias. Ferri died in 1511.
