Catherine Anne Hubback (7 July 1818 – 25 February 1877) was an English novelist, and the eighth child and fourth daughter of Sir Francis Austen (1774–1865), and niece of English novelist Jane Austen. She began writing fiction to support herself and her three sons after her husband John Hubback was institutionalized. She had copies of some of her aunt's unfinished works and, in 1850, remembering Austen's proposed plot, she wrote The Younger Sister, a completion of Jane Austen's The Watsons. In the next following thirteen years, she completed nine more novels.
