Leonardo Visconti

Leonardo Visconti (died c. 1376) was the natural son of Giovanni Visconti, archbishop and co-lord of Milan. In 1352 he served as podestà of Novara, but a quarrel with his father drove him from Visconti territory, and he took shelter at Viazalla castle in the Vercelli country with his wife.

He then entered the service of John II, Marquess of Montferrat, and helped the marquess acquire Alba, Asti and Cuneo, setting himself against his Milanese Visconti kinsmen. He died around 1376.
