On 10 December 2014, her twins were born. Daughter Gabriella Thérèse Marie was born first followed by her brother Jacques Honoré Rainier. Due to male-preference cognatic primogeniture, Jacques is first in line to the throne.

The 38-year-old Princess has been spotted at events around Monaco in the lead up to National Day including visiting Red Cross headquarters and giving parcels to refugees.

The date of the National Day is traditionally determined by the reigning Prince. The previous Princes often chose the day of the saint they were named after. However, when Prince Albert II ascended the throne he ended this tradition by choosing the same day as his father Prince Rainier III.

The date of the National Day is traditionally determined by the reigning Prince and is held annually with fireworks and a mass service.

National day is typically celebrated with fireworks over the harbour the evening before and a mass in the St. Nicholas Cathedral the next morning. The people of Monaco may celebrate by waving the Monegasque flag.

THE MONACO ROYAL FAMILY TREE AND WHAT YOU NEED TO KNOW ABOUT THEM

For hundreds of years the Monaco royal family has descended from the House of Grimaldi apart from during French occupation between 1793 and 1814.

The House of Grimaldi, descended from Otto Canella, a Genoese statesman, and taking their name from his son Grimaldo, were an ancient and prominent Guelphic Genoese family. Members of this family, in the course of the civil strife in Genoa between the Guelphs and Ghibellines, were banned from Genoa in 1271 and took refuge in Monaco.

François Grimaldi seized the Rock of Monaco in 1297, starting the Grimaldi dynasty, under the sovereignty of the Republic of Genoa.

The most recent Princes of Monaco include Rainier III (who reigned 1949–2005), who was the grandson of Louis II (1922 – 1949) and now his son Albert II (2005 – incumbent), whom has been regent for his father since 2005.   

By convention, sovereign European houses are reckoned in the male line.[citation needed] Therefore, since 1731, it has been determined genealogically that it was in fact the French noble House of Goyon-Matignon that ruled as Princes of Monaco until 1949.
