On 5 August 1855 her first husband Sir William Chatterton died. After two years of grieving, Georgiana and Rebecca Orpen, Sir William's niece, who was in her care, decided to resume regularly attending parties and social gatherings. Soon after, Georgiana met a fellow novelist, Edward Heneage Dering. Edward's intention was to marry Rebecca, but due to poor hearing Lady Chatterton assumed the proposal was made to her. On 1 June 1859, the widow married Dering and they took up residence in 1869 with Rebecca and her husband Marmion, the last old squire of Baddesley Clinton Hall, Warwickshire. There Marmion and Dering took to wearing 17th-century costume. Within six years of their marriage, Dering was received into the Roman Catholic Church. Georgiana herself wavered, but after a correspondence with William Bernard Ullathorne, Roman Catholic Bishop of Birmingham, she converted as well in August 1875. Her husband stated that she lived by three principles during her lifetime: to know the will of God and do it; to see everything exactly how it was, without reference to her own wishes; and never to turn aside from a difficulty, however easily avoided. Georgiana Dering died at Baddesley Clinton Hall on 6 February 1876, aged 69.
