"Agnese del Maino (c. 1411 – 13 December 1465) was a Milanese noblewoman and the mistress of Filippo Maria Visconti, the last legitimate Duke of Milan of the Visconti dynasty. Agnese was the mother of Bianca Maria Visconti, who succeeded to the title of Duchess of Milan in 1450, despite her illegitimacy." - (Wikipedia (en) 17.11.2019)
