However he was eight years old when the novel adaptation Peter and Wendy was published, and in later editions of the play, the character Michael Darling's middle name was changed to "Nicholas".

Two of Davies's brothers died before he was an adult: George was killed in combat in World War I in 1915, Michael drowned with a close friend in 1921.

Davies attended Eton College, and started at Oxford University in 1922, but continued to spend holidays with Barrie.

In The Lost Boys, he was portrayed at various ages by Stephen Mathews, Jason Fathers, Matthew Ryan, and David Parfitt (later award-winning producer).

He was not included in the 2004 film Finding Neverland based on the story of Barrie's relationship with the family and the writing of the play.
