The Marjorie Bowen Papers consist of the literary and personal papers of the British writer Gabrielle Margaret Vere Campbell, who published hundreds of works of fiction, historical fiction, and history, as well as reviews and opinion pieces, in the first half of the twentieth century. The collection primarily contains manuscripts, typescripts, and printed versions of her writings, with photographs, press cuttings, and some correspondence files that include letters from authors Samuel Clemens (Mark Twain), Sir Arthur Conan Doyle, and Rebecca West. Also in the collection are papers of Bowen's mother, the author and playwright Mrs. Vere Campbell, and Bowen's son Hilary Long, in particular more than three hundred letters from Bowen to Long. The bulk was sent to Long during World War II while he was serving in the King's Royal Rifle Corps (KRRC), and includes many examples of wartime V-mail. Auxiliary material covers the lives of family members, including ancestors in the Bowen, Ellis, and Campbell families. Present are three manuscript memoirs of Marjorie Bowen's ancestors: her grandfather, Bishop John Ellis (1785-1855), a Moravian missionary who spent several decades in Antigua, Jamaica, and Barbados, written by his widow; her grandmother Elizabeth Bowen Ellis (1792-1842), written by her son (Bowen's father) Charles Bowen Ellis; and a memoir of Charles Bowen Ellis (1821-1887), also a Moravian minister and missionary, written by one of his siblings.
