The series includes extensive correspondence with Charlesworth's family, most importantly her own letters to her parents, beginning before the Second World War in England. Then during the 1939-1945 period when her letters describe her experiences as a child sent away from England for safety, studying at Trafalgar School and the High School of Montreal, spending her summers at a camp in the Laurentians, and starting her acting career with the Montreal Repertory Theatre. The letters carry on after her immigration to Canada in 1956, describing her trip with Jean Roberts and Ruth Barratt to Calgary, her subsequent founding of the Red Barn Theatre with Roberts, and the other events and experiences in her life in Canada. The series includes letters to Charlesworth from old family friends, from family retainers, and from Jean Roberts' mother.
