On February 22, 1942, Straight married Louis Dolivet, Free French Leader, in Polk County, Iowa. At the time, Dolivet was a speaker at the National Farm Institute and Straight was in the middle of the midwest road show of "Twelfth Night". Her mother Dorothy Elmhirst and stepfather Leonard K. Elmhirst attended the wedding with her brother Michael Straight and his wife Belinda Crompton. Dolivet was in the French Air Force until June 1940 and was the co-editor of "The Free World", a magazine published by the International Free World Association, of which he was secretary general. At the time of the wedding, her elder brother, Whitney Straight, had been missing since August 1941, when his plane was shot down on the French coast.
