[4][5][6] According to Eugenio Gamurrini and Ludovico Jacobilli the Simonetti from Terni, Milan, Florence, Jesi, Lucca, Osimo, Cingoli, had a single origin.

According to Jacobilli the Simonetti branches were all descendants of a single line of Lombard barons that held fiefs in central Italy.

[7] Gamurrini in his Istoria genealogica delle famiglie nobili Toscane et Umbre studied manuscripts that linked the Simonetti of Milan, Lucca and Florence to Teuprando, a Lombard lord living in Lucca and a descendant of Aripert I, King of the Lombards (see Bavarian dynasty).

Other noble families from Lucca also recognized Teuprando as their ancestor, including the Rolandinghi, Soffredinghi, and Opezinghi.

[10] According to Villani the family was forced to renounce all its titles in Florence and was reduced to popolani (common citizens) for a short time.

In Canto XVI of Paradiso, Dante says: Therefore should not appear a marvellous thing What I shall say of the great Florentines Of whom the fame is hidden in the Past.

In the year 1308 the Simonetti, Quartigiani and other noble families were banned from holding public offices in Lucca.

After a few months in office Castruccio Castracani turned against his protectors and plotted against the Quartigiani clan, including the Simonetti branch of the family.

[15] In a papal bull of August 9, 1805 Pope Pius VII created the title of Prince of Musone for Count Don Raniero Simonetti from Ancona and his descendants.
