Between 1875 and 1911, Isabella Smith O’Donnell and her daughter, Esther, corresponded with family back in Sheffield, England and with her sister and relatives in the United States and Canada. Her nephew, Frederick Smith, was the most regular correspondent, but there are also letters from family in Ecclesall Bierlow where she was born and other areas of Sheffield such as Wadsley Bridge, Nether Hallam, Attercliffe and others.
In the Victorian period memorial cards were printed for the death of a loved one. This set of memorial cards were sent to the O’Donnell family to inform Isabella of the passing of her family in Sheffield. At one time, this set appears to have been pasted in a scrapbook and are, alas, the worse for wear. They remain legible due to the materials used.
