Marie-Angélique Memmie Le Blanc was a famous feral child of the 18th century in France who was known as The Wild Girl of Champagne, The Maid of Châlons, or The Wild Child of Songy.

A feral child is a young individual who has lived isolated from human contact from a very young age, with little or no experience of human care, social behavior, or language. Such children lack the basics of primary and secondary socialization. The term is used to refer to children who have suffered severe abuse or trauma before being abandoned or running away. They are sometimes the subjects of folklore and legends, often portrayed as having been raised by animals. While there are many cases of children being found in proximity to wild animals, there are no eyewitness accounts of animals feeding human children.
