Henrietta Georgiana Marcia Lascelles Chatterton, Lady Chatterton (née Iremonger; other married name Dering] (11 November 1806– 6 February 1876), was a British traveler and author.
Lady Chatterton was the only child of the Rev. Lascelles Iremonger, prebendary of Winchester Cathedral, and Harriett Gambier, youngest sister of Admiral Lord James Gambier. This was the second marriage for Rev. Iremonger, who died on 6 January 1830. Lady Chatterton was born at 24 Arlington Street, Piccadilly, London, on 11 November 1806. On 3 August 1824 she married Sir William Abraham Chatterton of Castle Mahon, County Cork, bart.
In 1837 her first book, Aunt Dorothy's Tales, was published anonymously in two volumes. Two years afterward it was followed by Rambles in the South of Ireland, which was so successful that the first edition sold out in a few weeks. After this she wrote many tales, novels, poems, and accounts of travels under the name Georgiana Chatterton.[1] Cardinal John Henry Newman praised the refinement of thought in her later works of fiction.
The Great Irish Famine in 1845–1851 deprived her husband of his rents. They retired to a small residence at Bloxworth in Dorset, where they lived until 1852. They then removed to Rolls Park, Essex, and Sir William Chatterton died there on 5 August 1855. On 1 June 1859 the widow married Edward Heneage Dering (b 1827), youngest son of John Dering, rector of Pluckley, Kent, and prebendary of St Paul's Cathedral, who had retired from the army in 1851. Within six years of their marriage Mr. Dering entered the Roman Catholic Church. She herself long wavered, but after a correspondence with William Bernard Ullathorne, bishop of Birmingham, she was received into the Roman church in August 1875.
She died at Malvern Wells, a village in Worcestershire, England, on 6 February 1876.
