Jane (last name is not given) is the daughter of Wendy Darling and appears briefly in most versions of the story as the one to follow Peter to Neverland after Wendy has grown up and lost the ability to fly.
In Fox's Peter Pan and the Pirates she makes a brief cameo by means of time travel. While in the past, she meets her mother who at the time is still living with Pan and having adventures in Neverland. Jane is overjoyed to see that the stories her mother told her are all true and even meets her mother's younger self. However, while she and her mother do love each other, Jane ultimately breaks her mother's heart because her very existence proves to Wendy that she will one day leave Neverland and grow up.
Jane's largest role was in the film Return to Neverland, where she is portrayed as a cynical, no-nonsense, down-to-earth girl who refuses to believe her mother's stories about Peter Pan or in anything else for that matter. In fact, unlike Wendy, she is not interested in playing "mother" for the Lost Boys and spends most of her time in Neverland just wanting to leave. She was forced to grow up as quickly as she did, losing both her faith and in effect her childhood, due to living in London during the Blitz. In the movie, she is mistaken for her mother by Captain Hook, who kidnaps her in a scheme to get Peter.
Jane eventually marries and has a daughter, called Margaret in Barrie's original story and called Moira in Hook. In Barrie's original story, Peter flies away with Margaret and "thus it will go on," meaning Peter will come for each of Wendy's female descendants when they are young, and he never grows up. However, in the film Hook, Moira eventually marries Peter Pan, they grow up, and have two children: Jack and Maggie.
