Giovanni's father, a veterinarian, was a close friend of the Redemptorists of Madonna dell'Olmo, Montecchio Emilia, and after the closure of the convent in 1859, a sizable portion of its library was placed in the Mercati home.
Traces of Roman civilizations were found - including remains if the defensive walls - and other towns in the area : castrum di Vicus Mercati (now Vimercate), the winter encampment Hiberna Regis (now Bernareggio), Caesarea Novella (Now Sernovella, frazione di Verderio) and Miliarium Tertium (Terzuolo, frazione in Robbiate).
