Acton was born into a prominent AngloItalianAmerican family at Villa La Pietra, his parents house one mile outside the walls of Florence, Italy. He claimed that his greatgreatgrandfather was Commodore Sir John Acton, who was prime minister of Naples under Ferdinand IV, and grandfather of the Roman Catholic historian John Acton.
