Daphne du Maurier was born in London, the second of three daughters of the prominent actor-manager Sir Gerald du Maurier and actress Muriel Beaumont (maternal niece of William Comyns Beaumont). Her grandfather was the author and Punch cartoonist George du Maurier, who created the character of Svengali in the novel Trilby.
These connections helped her in establishing her literary career, and du Maurier published some of her early work in Beaumont's Bystander magazine. Her first novel, The Loving Spirit, was published in 1931.
Du Maurier was also the cousin of the Llewelyn Davies boys, who served as J.M. Barrie's inspiration for the characters in the play Peter Pan, or The Boy Who Wouldn't Grow Up. As a young child, she met many of the brightest stars of the theatre, thanks to the celebrity of her father. On meeting Tallulah Bankhead, she was quoted as saying that the actress was the most beautiful creature she had ever seen
