"Francesco Peretti di Montalto (1597 – 4 May 1655) was an Italian Catholic Cardinal.
Peretti was born to an Italian noble family. By birth he was to be the successor of his father; Prince of Venafro, Venetian patrician, Marquis of San Martino, Count of Celano and Baron of Pescina. However, he was also a nephew of Cardinal Alessandro Peretti di Montalto and a great-grand-nephew of Pope Sixtus V. As his father´s only son he was urged to marry to continue the family line. He chose the Princess of Cesi but his father disapproved. Dismayed by his father´s prohibition he ran away from home and went to Rome to become a priest." - (en.wikipedia.org 08.06.2020)
