Five letters sent from Ruth Darwin to Ida Darwin dated 2-30 November 1910, including a single letter from Ruth's brother Erasmus to Ida. The letters make some reference to family matters but also give an account of Ruth's activities in Saltburn-by-the-Sea where she is residing with Erasmus which include shopping trips to furnish the house, charitable visits in and around Middlesbrough, a visit to the Wynne-Finch family in Stokesley, Yorkshire, and her opinions on Anthony Trollop's novel 'The Small House at Allington' and E. M. Forster's 'Howards End'. The letters also express concern for Erasmus and his feelings of disappointment over an unrequited love for 'Celia' who has been identified as Margaret Cecilia Newbolt (1890-1975), the only daughter of Sir Henry John Newbolt (1862-1938) and Margaret Duckworth (b. 1867/8).
