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.
Her case is more controversial than that of some other feral children because a few modern-day scholars have regarded it as either wholly or partly fictional. However, in 2004, the French author Serge Aroles argued that it was indeed authentic, after spending ten years carrying out archival research into French and American history.Aroles speculates that Marie-Angélique had survived for ten years living wild in the forests of France, between the ages of nine and 19, before she was captured by villagers in Songy in Champagne in September 1731.
