It is of French and Hebrew origin, and its meaning is "grace". Variant of Ann. Ninon de Lenclos was a 17th-century aristocrat and Parisian belle famous for her wit and beauty.
Ninon is very kind and crazy but she lies sometimes but not everyone is perfect, she is really good at dance and loves animals. If you don't have a Ninon in your live go and search for one.
