Sir Percy and Lady Shelley were once visited at Boscombe by Ianthe Esdaile, the daughter of Shelley and his first wife Harriet. Lady Shelley took Ianthe to her ‘sanctum’ and showed her the family papers and relics: ‘I then left her alone for an hour. On my return I found her bathed in tears and sobbing bitterly. She had been touched; she knew her father a little bit at last. "Send my children to me," she said; "let them come and love him too." Among the few items Ianthe had relating to her father was this notebook, containing fifty-six or fifty-seven youthful poems by Shelley, and one or two probably by Harriet. Shelley had sent the poems to Thomas Hookham, who had declined to publish them.
In the 1880s Edward Dowden learned of the notebook and persuaded Ianthe's son, Charles Esdaile, to lend it to him for his work on his Shelley biography. The notebook remained in the Esdaile family but was not, it seems, always reverenced. On 13 May 1953 Harold Nicholson wrote to Edmund Blunden informing him that the notebook was kept in a chest of drawers in the attic by its eccentric and difficult owner, Mr. Esdaile, who foamed at the mouth at the very mention of Shelley. There was a fear that, in an excess of rage, he might throw the manuscript into the fire. Fortunately, the 'Esdaile notebook' escaped the flames, and came up for sale in 1962. It was purchased by the Carl H. Pforzheimer Library and its contents were published in 1964, edited by Kenneth Neill Cameron.
