Boyer was quoted in the American news media as claiming his wife would be relinquishing her career, as he felt married women should not work but devote their time and attention to bringing up their children. However, Paterson continued to work. Indeed, arguably her greatest commercial successes came in the five years immediately following her marriage to Boyer. She continued to appear in at least one film per year until the outbreak of World War II in 1939, when she, her husband and Maurice Chevalier, as Europeans, devoted themselves to supporting the war effort of Britain and France. It was the war which effectively brought an end to her film career. On 9 December 1943, two years after her husband Charles became an American citizen, she gave birth to their only child, Michael Charles Boyer, in Los Angeles, California.
