At the time of her birth, her parents were not married; they subsequently married in 1951, legitimatizing her and her two younger siblings{Source}.
However, this did not place her and her siblings in succession for Monaco's throne in line for the throne of Monaco{Source}.

Due to when her uncle turned 21 years of age in 1944, her grandmother (Princess Charlotte) and and her mother, Princess Antoinette formally renounced their succession rights, however with the changes in the 2002 succession laws, Princess Antoinette and her line were briefly back in succession for the throne from 2002-2005.

She and her two siblings were originally given the surname Grimaldi, but when her mother received the Barony of Massy as a wedding present from her brother in December 1951, then Princess Antoinette changed her children's last name to de Massy to reflect her title.  However, Elisabeth and her siblings are not entitled to use Baron or Baroness of Massy as it is not considered hereditary nor do they have the courtesy titles as the children of a baroness. like they would in the United Kingdom (UK child of baron titles: The Honourable First name last name. Example: Peter Trevor Maxwell, 28th Baron de Ros's children are The Hon. Finbar Maxwell, The Hon. Katherine Maxwell & The Hon. Jessye Maxwell){Source}. Elisabeth-Anne is a baroness via her first marriage, not through hereditary titles or titles from Monaco. 

Elisabeth has been married twice, and has two children-one from each marriage.

1.  Baron Bernard Alexandre Taubert-Natta (m. 1974-1983, he died in 1989)
1. Baron Jean-Leonard Taubert-Natta (1974)
1. Baroness Susanna Taubert-Natta (m. 2009)
2.  Nicolai Vladimir Costello (m. October 1984-1985)
1. Melanie-Antoinette Costello de Massy (1985, professionally known as Melanie-Antoinette de Massy)

With the death of her uncle in 2005, she lost her place in the line of succession for the Monégasque throne, however, she, her children, and her brother, his family and her youngest sister (who died in 1989)'s son and his family remain in the "pool" of familial persons eligible to be selected for the Crown in the event of the extinction of the descendants of Prince Rainier.




She is godmother to her cousin, Princess Stephanie of Monaco.
She is the oldest grandchild of Princess Charlotte of Monaco, The Duchess of Valentinos & Prince Pierre of Monaco, The Count of Polignac.She is of Mexican, French, Scottish, English, German, Italian descent on her mother's side (there might be more here as well)
After her parents divorce, she became the stepdaughter of Margot James.Through her stepmother, she was the step-niece of:

• Dr. Charles S. James 
• Mrs. Holly W. James

She is related to the first official Monegasque ambassador to the US, Gilles Noghès, who was Monaco's first official ambassador from 2006-2009. Prior to Gilles appointment, Monaco was represented by France's ambassador. She was close to her uncle Rainier growing up.
She grew up in the little town of Èze, France, which is about a 20 minute car ride to Monte Carlo.
Sometimes her birthday is credited as 14 July 1947, which is actually her birthday, I'm unsure.
