This collection documents the Yeats family through their artwork, correspondence, manuscripts, notebooks, and photographs. Materials were created by siblings W. B., Elizabeth Corbet, Lily, and Jack B. Yeats; their father, John Butler Yeats; the wife of W. B., Georgie Yeats; the daughter of W.B., Anne Yeats; and the son of W.B., Michael B. Yeats. Topics include W. B.'s writing projects, business matters, and family matters; W. B.'s and Lily’s interest in the occult and psychic visions; and Elizabeth's management of Cuala Press, a family business. In addition, the collection includes extensive correspondence between W. B. and his mistress Margot Ruddock, and between Ruddock and the Indian guru Purohit Swami, with whom W. B. translated The Ten Principal Upanishads. Notable materials include notebooks containing drafts of W. B.’s works "Love and Death," Supernatural Songs, and The Wanderings of Oisin; portraits, caricatures, and photographs of W. B.; and artwork by W. B., Jack B., John Butler, and Anne Yeats. Cards, calendars, and a finely detailed embroidery offer examples of work produced by the Yeats at Cuala Industries.
