In page Agnese del Maino:

"

Agnese was born around 1411 in Milan. She was the daughter of Ambrogio del Maino,[citation needed] a Count Palatine and ducal questore or chief of police. Her mother's name and identity is unknown. Agnese had two brothers, Lancillotto del Maino and Andreotto del Maino, who were both courtiers and members of the ducal council. She became the mistress of Filippo Maria Visconti, the last duke of Milan of the Visconti dynasty, whose wife Beatrice Lascaris di Tenda had been executed for adultery in 1418 and had produced no children.
