Carolyn Rossington is Francis twin sister, who died 17 years earlier. Bullied and tormented by Miss Laura her whole life, she accepted Francis invitation to join him in Lake Garda after the war. She fell in love with a local doctor and they became engaged, but he died in a car crash. Pregnant, Carolyn tried to drown herself, but was rescued by Giorgio, who later married her and raised Pietro as his own son when Carolyn died a few years later. Carolyn had insisted that Pietro not know that Il Capitano was his uncle until her turned 18, to ensure his safety from Miss Laura.
