Padre Narciso da Milano, whose real name was Giuseppe Burocco, was not uncovered until 1994. His uncle, P. Giuseppe Bernardino Burocco, is a Friar Minor (Observant), chronicler and writer. Following his tracks, the young Giuseppe joins Sant'Angelo Franciscan Convent in Milan 1689, he is named Frà Narciso, and makes his profession of faith on 25th March 1691. Very young clerks are not uncommon in this time.
The convent's archives quote him only once in 1727,but their major part was destroyed in the fire caused by Spanish troops in 1746, during their retreat forced by Austrians seizing back Milan. The church was spared but the library burnt down completely.
