 The Mattei gave eight Cardinals to the Catholic Church, among them Girolamo Mattei (1586), Gaspare Mattei (1643), Alessandro Mattei (1803), Mario Mattei (1832), Lorenzo Girolamo Mattei (1833) and (as late as 1875) Ruggero Luigi Emidio Antici Mattei.The founder of one powerful branch of the Mattei was Giovanni Giacomo Mattei.Mattei family lines reportedly went back to an early Roman family, the Papareschi, and their ancestors included Pope Innocent II (1130–1143).
