Wendy

Wendy is a given name generally given to girls in English-speaking countries.
In Britain, Wendy appeared as a masculine name in a parish record in 1615. It was also used as a surname in Britain from at least the 17th century. Its popularity in Britain as a feminine name is owed to the character Wendy Darling from the 1904 play "Peter Pan" and its 1911 novelisation "Peter and Wendy" by J. M. Barrie. Its popularity reached a peak in the 1960s, and subsequently declined. The name was inspired by young Margaret Henley, daughter of Barrie's poet friend W. E. Henley. With the common childhood difficulty pronouncing "R"s, Margaret reportedly used to call him "my fwiendy-wendy".
Chinese women with the same or similar-sounding characters as their given names often anglicise their names as "Wendi" or "Wendy" (e.g. Wendi Deng, Wendy Kweh).
In Germany after 1986 the name Wendy became popular because it is the name of a (targeted specifically at young girls) about horses and horse riding.
