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.
