Mary Wright Sewell Mary Wright Sewell Mary Wright Sewell (; 6 April 1797 – 10 June 1884) was an English poet and children's author. Though popular for writing juvenile bestsellers in her day, she is better known today as the mother of Anna Sewell, the author of "Black Beauty". Mary was born into the Quaker faith in 1797, and she married Isaac Sewell on the 15 June 1819 at Lamas in Norfolk. Her daughter Anna was born in 1820 and her son Philip two years later. Her husband Isaac had a number of ill-advised businesses and he declared himself bankrupt after his son
Anna Sewell contributed to her love of horses and concern for the humane treatment of animals. In 1836, Sewell's father took a job in Brighton, in the hope that the climate there would help to cure her. At about the same time, both Sewell and her mother left the Society of Friends to join the Church of England, though both remained active in evangelical circles. Her mother expressed her religious faith most noticeably by authoring a series of evangelical children's books, which Sewell helped to edit, though all the Sewells, and Mary Sewell's family, the Wrights, engaged in many other good works.
