Peter Pan; or, the Boy Who Wouldn't Grow Up or Peter and Wendy is J. M. Barrie's most famous work, in the form of a 1904 play and a 1911 novel.
 Both versions tell the story of Peter Pan, a mischievous yet innocent little boy who can fly, and has many adventures on the island of Neverland that is inhabited by mermaids, fairies, Native Americans and pirates.
 Peter has many stories involving Wendy Darling and her two brothers, his fairy Tinker Bell, the Lost Boys, and the pirate Captain Hook.
 The play and novel were inspired by Barrie's friendship with the Llewelyn Davies family.
 Barrie continued to revise the play for years after its debut until publication of the play script in 1928.
George Llewelyn Davies (20 July 1893 - 15 March 1915) was the eldest son of Arthur and Sylvia Llewelyn Davies.
 Along with his four younger brothers, George was the inspiration for playwright J. M. Barrie's characters of Peter Pan and the Lost Boys.
 The character of Mr. George Darling was named after him.
 He was killed in action in the First World War.
 He was the first cousin of the English writer Daphne du Maurier.
Sylvia Jocelyn Llewelyn Davies (25 November 1866 – 27 August 1910), "née" Sylvia du Maurier, was the mother of the boys who were the inspiration for the stories of Peter Pan by J. M. Barrie.
 She was the daughter of cartoonist and writer George du Maurier and his wife Emma Wightwick, the elder sister to actor Gerald du Maurier, the aunt of novelists Angela and Daphne du Maurier and a great-granddaughter of Mary Anne Clarke, royal mistress of Prince Frederick, Duke of York and Albany.
John "Jack" Llewelyn Davies (11 September 1894 – 17 September 1959) was the second eldest of the Llewelyn Davies boys befriended by Peter Pan creator J. M. Barrie, and one of the inspirations for the boy characters in the story of Peter Pan.
 He served in the Royal Navy during World War I.
 He was the first cousin of the English writer Daphne du Maurier.
Peter Llewelyn Davies MC (25 February 1897 – 5 April 1960) was the middle of five sons of Arthur and Sylvia Llewelyn Davies, one of the Llewelyn Davies boys befriended and later informally adopted by J. M. Barrie.
 Barrie publicly identified him as the source of the name for the title character in his play "Peter Pan, or The Boy Who Wouldn't Grow Up".
 This public identification as "the original Peter Pan" plagued Davies throughout his life, which ended in suicide.
 He was the first cousin of the English writer Daphne du Maurier.
Allahakbarries was an amateur cricket team founded by author J. M. Barrie, and was active from 1890 to 1913.
 The team was named in the mistaken belief that "Allah akbar" meant "Heaven help us" in Arabic (rather than "God is great").
 Notable figures to have featured for the side included Rudyard Kipling, H. G. Wells, Arthur Conan Doyle, P. G. Wodehouse, G. K. Chesterton, Jerome K. Jerome, A. A. Milne, E. W. Hornung, Henry Justice Ford, A. E. W. Mason, Walter Raleigh, E. V. Lucas, Maurice Hewlett, Owen Seaman, Bernard Partridge, Augustine Birrell, Paul Du Chaillu, Henry Herbert La Thangue, George Cecil Ives, and George Llewelyn Davies, as well as the son of Alfred Tennyson.
Nicholas "Nico" Llewelyn Davies (24 November 1903 – 14 October 1980) was the youngest of the Llewelyn Davies boys, who were the inspiration for J. M. Barrie's Peter Pan and the Lost Boys.
 He was only a year old when "Peter Pan, or The Boy Who Wouldn't Grow Up" hit the stage in 1904, and as such was not a primary inspiration for the characters of Peter and the Lost Boys.
 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."
 He was the first cousin of the English writer Daphne du Maurier.
The Davies boys (the family only used the double surname Llewelyn Davies in formal contexts) were the sons of Arthur (1863–1907) and Sylvia Llewelyn Davies (1866–1910), the daughter of the French-born cartoonist and writer George du Maurier, and sister of actor Gerald du Maurier.
 The boys were the first cousins of Gerald's daughter, the author Daphne du Maurier.
 They were the inspiration for J. M. Barrie's Peter Pan, in which several of the characters were named after them.
Sir William Llewelyn Davies (born William Davies, and adding "Llewelyn" after marrying Gwen Llewelyn) (11 October 1887 – 11 November 1952) was chief librarian of the National Library of Wales, Aberystwyth from 1930 until his death.
Peter Pan is a fictional character created by Scottish novelist and playwright J. M. Barrie.
