Expectant parents, Albert and Charlene, will welcome twins at the end of 2014
Marie has a great MMonegasquepast. Prince Albert's younger sister is called Stephanie Marie Elisabeth and he has two nieces with it as a middle name - Charlotte Marie Pomeline Casiraghi and Camille Marie Kelly Gottlieb. But it is in past generations that the name has most resonance for the Grimaldis.

Albert's father inherited Monaco via his own mother, Princess Charlotte, who was the daughter of Prince Louis II and his lover Marie Juliette Louvet. Charlotte was named as legitimate heir to her father and passed her succesion rights to Rainier, her only son, in 1944. Louis' own mother had been named Mary while her mother had been a German princess, Marie Amelie of Baden.
Princess Marie Amelie of Baden is the great, great, great grandmother of Albert II of Monaco
Prince Albert II's paternal grandfather, the Count of Polignac, was named Pierre Marie Xavier Raphael Antoine Melchior and was the son of Maxence Melchior Edouard Marie Louis. His grandfather was Count Charles Marie de Polignac who was the son of Count Camille de Polignac and his wife, Marie. The name is on just about every branch of the Monaco family tree. So it's perhaps no surprise that it's a favourite for a possible princess. Marie of Monaco has quite a ring to it.
