Mrs. Chevalier was a Maltese widow living in Rome with her two sons and six daughters. Her older son was arrested by the Fascists as a British subject. Her second son was officially attached to Swiss Legation staff, and was protected by his Swiss papers. Her youngest daughter was sent for safety to live in a convent. She and her five older daughters shared small apartment and were able to shelter quite a number of Allied POWs until forced to flee towards the end of the war. She and her family were members of the organization headed by Monsignor Hugh O'Flaherty to rescue Allied POWs and Jews from the German and Italian Armies and Fascists during World War II.
