Guarnaccia Mulucci

Guarnaccia Mulucci was a son of Bonleone of the Guelph Mulucci family, which had risen to dominate Macerata in the later thirteenth century through its lands and its loyalty to the pope.

Early in the fourteenth century the family split into two branches, Bonleone's and that of Guarnaccia's uncle Muluccio II. In 1306 Guarnaccia and Muluccio attended a settlement between Camerino and neighbouring communes, concluded in Macerata's communal palace under papal authority.

That same year he was among the guarantors for Macerata at the Church's provincial parliament at Montolmo. The family's offices usually lay within the Marches, but in 1309–1310 Guarnaccia served farther afield as captain of the people at Siena.
