Guglielmo Manfredi

Guglielmo Manfredi (1327 – c. 1367) was born in Imola, the natural son of Riccardo Manfredi, third signore of Faenza, and his mistress Zeffirina Nordigli, and was later legitimised. His father knighted him on 21 August 1340, two days before his own death, and he became lord of Fontanamoneta and co-lord of Bagnacavallo in Romagna.

He was also co-lord of Gambaraldo, Castiglionchio, Gattaia and Calamello, but his cousin Giovanni d'Alberghetto Manfredi took those from him. He died around 1367.
