Princess Vittoria of Savoy is the elder of the two biological children of Emanuele Filiberto, Prince of Venice and Piedmont & his wife, French actress Clotilde Courau, and was born 29 December 2003 in Geneva, Switzerland. She is a great-grandchild of the last King of Italy and the granddaughter of the present pretender to the throne, Vittorio Emanuele, Prince of Naples, and his wife Marina. She also has two adopted brothers who were adopted from Kenya in January 2011, Alan and Moses, and a sister named Luisa, who was born in 2006.
I imagine the family is living a relatively normal life in either France or Switzerland, where she likely goes to school. I also imagine that with a French mother and Italian father, she speaks at least both French and Italian.
