Weny is a female name. Its popularity is attributed to the character Wendy Darling from the children's play and novel Peter Pan, by J.M. Barrie. The character Wendy was inspired by a real girl. Barrie befriended young Margaret Henley, daughter of Barrie's friend W.E. Henley. Margaret used to call him 'my friendy-wendy'. Margaret died at the age of four in 1894 but was immortalized forever in Barrie's work. Although the name 'Wendy' appears as a boy's name in the 1881 census of England, Barrie is usually credited with its invention as a girl's name.
