Giovanni Pietro Calefati
From GATE
Giulio Fuligatti refers to Giovanni Pietro Calefati as a member of the Society of Jesus (G. Fuligatti, Vita di Roberto Card. Bellarmino della Compagnia di Giesù, In Roma : per Lodouico Grignani, 1644, p. 131), sender of a letter to Roberto Bellarmino. Anyway, jesuit sources don't report any information about a jesuit with this name.
