Andrea Knecht de Massy was born 16 October 2008 in Monaco, the eldest of four daughters of Donatella Knecht de Massy and K. Sébastien Knecht de Massy. She is the paternal granddaughter of Christine-Alix de Massy and paternal great granddaughter of Princess Antoinette of Monaco, Barone de Massy. She has three older sisters:
Because her father, she and her sisters *technically* lost their place in succession with the death of Prince Rainier in 2005, she and her family are known to keep out of the main limelight. Other than the occasional all family appearance, she's kept away from the media's glare. Because of her age, she did not attend Prince Albert's 2011 wedding with her parents and three older sisters.
She attended the private catholic school, L'Institut François d’Assise Nicolas Barré, along with her older sisters and second cousins once removed Princess Alexandra of Hanover and Camille Gottlieb until at least 2010 when her family moved to South Africa. She should presently be in the final year of nursery school.
