Who married Galeazzo Maria Sforza?

Galeazzo Maria Sforza (24 January 1444 – 26 December 1476) was the fifth Duke of Milan from 1466 until 1476. He was born to Francesco Sforza, a popular condottiero and ally of Cosimo de' Medici who would gain the Duchy of Milan in 1450, and Bianca Maria Visconti, Duchess of Milan on her own right. Sforza was betrothed into the Gonzaga family; after the engagement with Dorotea Gonzaga was called off, he married Bona of Savoy.

Bona di Savoia (Avigliana, 10 agosto 1449 – Fossano, 17 novembre 1503) fu duchessa consorte di Milano, reggente per pochi anni dopo la morte del marito. "Femme de petit sens", la definì il contemporaneo e politico francese Filippo di Comines, ossia donnicciola di poco intelletto. In linguaggio cifrato fu anche soprannominata Malhora.
