The Davies boys were the inspiration for the stories of Peter Pan by J. M. Barrie, in which several of the characters were named after them. They were the sons of Sylvia (1866–1910) and Arthur Llewelyn Davies (1863–1907). Their mother was a daughter of French-born cartoonist and writer George du Maurier and sister of actor Gerald du Maurier, whose daughter was author Daphne du Maurier. Their father was a son of preacher John Llewelyn Davies, and brother of suffragist Margaret Llewelyn Davies.

Sir James Matthew Barrie, 1st Baronet, was a Scottish novelist and playwright, best remembered as the creator of Peter Pan. He was born and educated in Scotland and then moved to London, where he wrote several successful novels and plays. There he met the Llewelyn Davies boys, who inspired him to write about a baby boy who has magical adventures in Kensington Gardens, then to write Peter Pan, or The Boy Who Wouldn't Grow Up, a 1904 West End "fairy play" about an ageless boy and an ordinary girl named Wendy who have adventures in the fantasy setting of Neverland.
