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 Daphne du Maurier, the writer. They were the inspiration for J. M. Barrie's Peter Pan, in which several of the characters were named after them.
