Margaret Sarah Carpenter and been purchased back by a family relative in December 2013 for restoration.
Among her exhibited portraits were those of Sir H. Bunbury (1822), Lady Denbigh (1831), and Lady King (better known as Ada Lovelace) (1835). Her last work was a portrait of Dr. Whewell. Three of her works are in the National Portrait Gallery, including portraits of her husband, Bonington and John Gibson, R.A.. There are also several 'leaving portraits' by her in the collection at Eton College. There is also one of her portraits at Frewen College, of Helen Louisa Frewen and her son Edward. Her "Portrait of a Lady" hangs in the Neill-Cochran House Museum in Austin, Texas.
Her portraits follow in the tradition of Lawrence, but Wood found them to be more fanciful and feminine character, particularly in her portraits of children.
In 1817, she married William Hookham Carpenter, Keeper of Prints and Drawings at the British Museum. Their children included two noted painters, another William and Percy Carpenter, who both travelled. She introduced her sister Harriet to the young painter William Collins. They eventually married, making Margaret the aunt to Wilkie Collins, novelist and friend to Charles Dickens. On her husband's death in 1866, she was given an annual pension of £100 by Queen Victoria. This award was partly based on her husband's service, but also in recognition of her own artistic merits. She died in London in her 80th year.
