Donna Olimpia Aldobrandini was born 20 April 1623, the daughter of Giorgio Aldobrandini (Prince of Meldola, Sarsina and Rossano) and Ippolita Ludovisi (daughter of Orazio Ludovisi, sister of Niccolò Ludovisi and a niece of Pope Gregory XV).
In 1638, she married Prince Paolo Borghese of the Borghese family who died in 1646. The following year, in 1647, she married Camillo Pamphili (son of Olimpia Maidalchini and nephew of Pope Innocent X) who renounced a cardinalate to become her husband. Part of her dowry of her second marriage was a collection of paintings (including masterpieces removed from the Duke of Ferrara's "Camerino d’Alabastro"), villas in Montemagnanapoli and Frascati, the great Aldobrandini estates in Romagna on the Corso in Rome and the Palazzo Aldobrandini.
Aldobrandini and Camillo Pamphili had five children including Giovan Battista Pamphili, Benedetto Pamphili and Anna Pamphili who married the Genoese nobleman Giovanni Andrea III Doria Landi in 1671.
