What is the surname of Wendy in the novel "Peter and Wendy" by J. M. Barrie?

Wendy Moira Angela Darling is a fictional character and one of the main protagonists of the 1904 play and 1911 novel "Peter and Wendy" by J. M. Barrie, as well as in most adaptations in other media. Her exact age is not specified in the original play or novel by Barrie, though it is implied that she is about 12–13 years old or possibly younger, as she is "just Peter's size". As a girl on the verge of adulthood, she stands in contrast to Peter Pan, a boy who refuses to grow up, the major theme of the Peter Pan stories. Wendy hesitates at first to fly off to Neverland, but she comes to enjoy her adventures. Ultimately, she chooses to go back to her parents and accepts that she has to grow up.

In the novel "Peter Pan", and its cinematic adaptations, she is an Edwardian schoolgirl. The novel states that she attends a "kindergarten school" with her younger brothers, meaning a school for pre-adolescent children. Like Peter, in many adaptations of the story she is shown to be on the brink of adolescence. She belongs to a middle class London household of that era, and is the daughter of George Darling, a short-tempered and pompous bank/office worker, and his wife, Mary. Wendy shares a nursery room with her two brothers, Michael and John.
