According to the principality's inheritance law which favour males Jacques is his father's heir. He will be known as His Serene Highness The Hereditary Prince of Monaco, Marquis of Baux.
He is named after Jacques I, who came from an ancient Norman family and reigned in the 18th century. Meanwhile, five Honorés have sat upon the throne of Monaco.
Rainier is, of course, to honour Albert's beloved father, who died almost ten years ago on 6 April, 2005.
Jacques' sister is Her Serence Highness The Countess of Carladès. Gabriella seems to have been a personal choice for the couple, perhaps picked by 36-year-old Charlene herself.
As for her other names, there was a Monegasque princess in the 18th century called Marie Thérèse de Choiseul, known for her beauty, mischievous behaviour and courage. Marie is also one of the middle names of Charlotte Casiraghi, Albert's niece.
