A Memoir of Jane Austen by James Edward Austen-Leigh

According to Wikipedia: "A Memoir of Jane Austen is a biography of the novelist Jane Austen (1775–1817) published in 1869 by her nephew James Edward Austen-Leigh. A second edition was published in 1871 which included previously unpublished Jane Austen writings. A family project, the biography was written by James Edward Austen-Leigh but owed much to the recollections of Jane Austen's many relatives. However, it was the decisions of her close friend and sister, Cassandra Austen, to destroy many of Jane's letters after her death that shaped the material available for the biography."
