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.
Giuseppe Baini
He was born at Rome. He was instructed in composition by his uncle, Lorenzo Baini, and afterwards by G. Jannaconi. In 1814, he was appointed musical director to the choir of the pontifical chapel, to which he had as early as 1802 gained admission because of his fine bass voice. His compositions, of which very few were published, were considered favourable specimens of the severe ecclesiastical style; a ten-part Miserere of his, composed for Holy Week in 1821 by order of Pope Pius VII, has taken a permanent place in the services of the Sistine chapel during Passion Week. Baini held a higher place, however, as a musical critic and historian than as a composer, and his "Life of Palestrina" ("Memorie storico-critiche della vita e delle opere di Giovanni Pierluigi da Palestrina", 1828) was described by the "1911 Encyclopædia Britannica" as being "one of the best works of its class". The phrase "Il Principe della Musica", which has become firmly associated with the name of Palestrina, is found in the aforementioned biography.
