- Louis Robert Paul Ducruet (1992)
- Pauline Grace Maguy Ducruet (1994)
She is considered one of the "lucky" ones of the royal illegitimate children. She is fully acknowledged by her mother, a princess, and is rarely hidden from family events, which over the years have included: her uncle Albert's enthronement, the circus festivals (2009,2010,2012, 2013, 2014, 2015), the *NEW GENERATION* Festival (2012, 2014, 2015), Monaco Beach Soccer 2013 For Fightaids, her uncle's civil and religious wedding ceremonies, and the Louis Vuitton Cruise Line Show 2015, among other events over the years. In 2015, she took part in her uncle's 10 year succession anniversary concert and assisted her aunt and uncle and older brother with passing out Christmas gifts at the palace.
She was likely named for:
- Camille: likely a name her mother liked, however it could also be speculated that it is after Prince Honoré Camille Léonor Grimaldi de Goyon de Matignon
- Marie: likely, a name Princess Stephanie liked, but it could also be speculated that the name could be after her great-grandmother, Marie Juliette Louvet. Marie is a common name, too, in general and in the Grimaldi family. Camille's cousin Charlotte is Charlotte Marie Pomeline Casiraghi and is one of her mother's names.
- Kelly: in honor of her late grandmother, Grace Patricia Kelly.
While she was young, her mother picked up her, and her older half-siblings and whisked them off to travel with the circus from 2001 to early 2004. It was during these years that Camille was home-schooled by Princess Stephanie and she discovered an interest in gymnastics and theatre.
Upon their return to Monaco in 2004, she continued to attend local public schools for elementary and middle school. However, it has been recently discovered, perhaps because of her media-shy father or the fact that numerous of her cousins (Princess Alexandra,and the Knecht de Massy girls) attend the school as well, she have been enrolled in Lycée François d’Assise Nicolas Barré, where she *should be* in her final year.
As a youngster, due to her media shy father, she was often registered for school and events as Camille Marie Kelly Grimaldi.
Illegimate children are nothing new to Monaco's Princely courts. She is preceded by her great-grandmother Princess Charlotte of Monaco, three of her mother's paternal cousins (Elisabeth-Anne, Christian-Louis and Christine-Alix), two older half siblings, and 5 cousins. The Catholic Church did not consider her older Casiraghi cousins illegitimate until 1992 due to her mother's previous marriage to Phillipe Junot not being annulled. However, once Princess Caroline's marriage to Junot was annulled after the death of Stefano Casiraghi (father of Princess Caroline's older children) in 1992. Her uncle Prince Albert II of Monaco’s two older children, Jazmin Grace Grimaldi and Alexandre Coste, are also illegitimate. Her older maternal half-siblings, Louis and Pauline Ducruet, were both born prior to the marriage of their parents, were legitimized after the marriage in 1995. Her mother's cousins were, like her older brother and sister, legitimatized by marriage in 1951 (however, with the change of succession laws of 2002, the two surviving de Massy children lost their claims to the throne with the death of Prince Rainier in 2005).Her great-grandmother, Princess Charlotte was the only child of Prince Louis II and Marie Juliette Louvet, and had been adopted later by Prince Louis II, placing her in line for the throne of Monaco. However, in the case of Camille, Jazmin and Alexandre, due to the 2002 changes of the constitution of Monaco it is not possible for Princess Stephanie to adopt her (or for Prince Albert to adopt Jazmin or Alexandre) in order to place them in line for the throne. The only way Camille would be in line for the throne is that if her father was confirmed to be Jean-Raymond Gottlieb and he and Princess Stephanie were to marry. If that were to happen, Camille would be placed in line after her older sister, Pauline, in the 9th position for the throne. However, due to the passage of time and the fact that Princess Stephanie and Jean-Raymond broke up many years ago, this does not seem likely.
