Margherita Colonna
She was born in Palestrina about 1255. Her father, Oddone Colonna, died when she was about two years old. Her mother, who was also named Margherita and who was the sister of Matteo Rosso Orsini and a pious woman, died when Margherita was probably a little over ten years old. Margherita was left in the care of her older brothers.
Maffeo Barberini (1631–1685)
Despite the fact that 12-year-old Guistiniani stubbornly refused to marry her 22-year-old suitor, surprising few, the two were married at a lavish ceremony celebrated by Pope Innocent himself. After the ceremony, however, the child refused to go home with her new groom to allow the marriage to be consummated. Her mother, who had barely been involved in her upbringing, appealed to her by telling her that other girls were forced to marry decrepit old men and that, by comparison, Barberini was a far better option. When the child still refused, Maidalchini forced her granddaughter into a carriage that took her to the Palazzo Barberini and a new life as a daughter of the Barberini.
Barberini was later restored to his father's former title of "Prince of Palestrina" - nominal patriarch of the Palestrina comune owned by the Barberini family. He was likely also appointed Gonfalonier of the Church on the same basis. Barberini commissioned the construction of the "Church of Santa Rosalia" in Palestrina (opened in 1677) which includes a tribute to Maffeo's father Taddeo by Bernardino Cametti.
