and the characters of the Lost Boys and Wendy Darling's brothers, introduced in Barrie's 1904 play Peter Pan, or The Boy Who Wouldn't Grow Up and further immortalized in its 1911 adaptation as the novel Peter and Wendy. In 1904, the year when Barrie's play debuted, the Davies family moved out of London and went to live in Egerton House, an Elizabethan mansion house in Berkhamsted, Hertfordshire. After the deaths of their parents Their father died of a salivary sarcoma at Egerton in 1907, and their mother took them back to live in London; she developed lung cancer and died in 1910. Over the course of their illnesses, Barrie became more involved with the family, including providing financial support for them. With Sylvia's death, Barrie became the boys' trustee and guardian, along with their maternal grandmother Emma du Maurier, Sylvia's brother Guy du Maurier, and Arthur's brother Compton Llewelyn Davies.

Their father Arthur was troubled by Barrie's relationship with them, but that was based on its interference with his own relationship with them as their father, and he didn't care for the man personally. As an adult, Nico flatly
