Bolognese family, perhaps originally from Umbria, rose from the middle class to which it belonged thanks to the marriage of Cristoforo Boncompagni (1470 - 1546) with the noble Angela Marescalchi. In 1572 the son of Cristoforo and Angela, Ugo Boncompagni, was elected to the papal throne as the 226th pope of the Catholic Church with the name of Gregory XIII. Since then the luster and power of the family could only increase. Numerous members obtained important positions in the Church and 5, in addition to Ugo, were created cardinals: Filippo (1548 - 1586), Francesco (1592 - 1641), Girolamo (1622 - 1684), Giacomo (1652 - 1731), Ignazio Gaetano (1743 - 1790); of these, among other posts, one was Archbishop of Naples and two were Archbishops of Bologna, while another was also
