Marin eventually settled in Rome, where he became a cloth merchant and money lender near the Piazza of the Trinità dei Monti.

Giovanni, in return for his able administration of the Vatican finances, was created duke of Bracciano[2] and count of Pisciarelli by Pope Pius VI in 1794.

He was made, among other titles, a Roman Patrician in 1809, with confirmation from the Pope on 19 January 1813, and the duke of Poli e Guadagnolo in 1820.

He married Anna Maria Chiaveri née Schultheiss, a widow who came from a family of southern German merchants from the city of Donaueschingen.

Marino married the rich American heiress Mary Elsie Moore; they were the parents of Don Alessandro Torlonia, 5th Prince di Civitella-Cesi, who married the Infanta Beatriz of Spain, the daughter of King Alfonso XIII - one of their grandchildren is Princess Sibilla of Luxembourg; and of Donna Marina Torlonia di Civitella-Cesi, the wife of American tennis player Francis Xavier Shields and grandmother of the American actress Brooke Shields.
