This name was borne by Marilla Savelli, a 13th-century Roman noblewoman who was the sister of Giacomo Savelli (1210–1287), known to history as Pope Honorius IV (1285). She married twice, secondly to Agapito Colonna (1250–1300); they were the great-great-grandparents of Oddone Colonna (1369–1431), later Pope Martin V (1417).
