Giovanni Battista Crollalanza was born in Fermo in the Marche region, where his father Pietro, who had married Eufrosina Ricci, had moved from Chiavenna following the events of the late 700th century. Addressing the study of history, Giovanni Battista taught it in various Italian institutes. In Carpi he founded the Prince Umberto College, later becoming director of the National College of Imola. In Fermo he founded the «Giornale araldico» in 1874, in Pisa in 1875 «Accademia araldica», in 1879 «Annuario della nobiltà italiana».

Don Guanella, a young curate from Savogno, used the Storia del contado di Chiavenna to give lectures on the history of Prosto to his "docile" parishioners who attended the winter school.
