This collection, while primarily composed of the letters and papers of Esther Chalmers herself, and reflecting her own life and activities, also reflects those of her family, from her grandparents to her nieces and nephews, and of her friends, both in Britain and abroad. The papers concern mostly her own life and her association with Lucie Dejardin, the Belgian socialist, with papers concerning her kinfolk the Lorimers of Kellie (particularly James Lorimer and J H Lorimer) and her father Sir David Patrick Chalmers.
