Monaco’s royal family, a lineage touched by Hollywood legend Grace Kelly, joyfully welcomes its newest member: Pierre Casiraghi and Beatrice Borromeo‘s first daughter, Bianca Caroline Marta, continuing a captivating dynastic story.
The glamorous principality of Monaco is abuzz with royal baby joy once again! Pierre Casiraghi, grandson of the iconic Hollywood actress-turned-royal Grace Kelly, and his impeccably stylish wife, Beatrice Borromeo, have welcomed their third child and first daughter. The arrival of Bianca Caroline Marta Casiraghi marks another beautiful chapter in the Grimaldi family’s ongoing story, a narrative that continues to fascinate fans of classic Hollywood and European royalty alike.
The news, confirmed on October 14, reveals that little Bianca made her debut on October 4, bringing immense happiness to the couple and to Pierre‘s mother, Princess Caroline, who is now a grandmother many times over. This new addition is particularly special as she is the couple’s first daughter, joining her two older brothers.
A Name Steeped in Family Tradition and Heritage
The choice of Bianca Caroline Marta for their daughter’s name is a beautiful testament to the family’s deep roots and cherished personal connections. Bianca, an Italian name meaning “white” or “fair,” elegantly reflects Beatrice‘s rich Italian heritage. The middle names hold even more profound significance.
- Caroline is a heartfelt homage to Pierre‘s mother, Princess Caroline of Hanover, a prominent figure in the Monaco royal family and daughter of Grace Kelly.
- Marta honors Beatrice‘s late maternal grandmother, Marta Marzotto, a renowned Italian fashion designer and socialite whose influence on Italian style was legendary.
This thoughtful naming convention reinforces the strong family bonds and the blend of Monegasque royalty with Italian aristocracy that defines Pierre and Beatrice‘s union.
Growing the Casiraghi-Borromeo Family: Stefano and Francesco
Before the arrival of their daughter, Pierre (38) and Beatrice (40) were already proud parents to two sons: Stefano Ercole Carlo Casiraghi, aged 8, and Francesco Carlo Albert Casiraghi, aged 7. Stefano, born in February 2017, and Francesco, who arrived in May 2018, were also named with significant family tributes, continuing a pattern of honoring their lineage, as reported by Harper’s Bazaar US at the time of Francesco‘s birth. The family’s public appearances often showcase the playful dynamic between the brothers, now with a new sister to complete their charming trio.

Pierre and Beatrice: A Modern Royal Love Story
Pierre Casiraghi, the youngest child of Princess Caroline and her second husband, the late Stefano Casiraghi, represents the glamorous face of Monaco’s younger royals. His wife, Beatrice Borromeo, is a journalist and documentary filmmaker from a distinguished Italian aristocratic family. Their romance culminated in not one, but two lavish ceremonies in 2015, widely celebrated as the “chicest of the summer” by fashion and lifestyle publications.
Their civil service in July 2015 at the Prince’s Palace of Monaco was followed by a breathtaking religious ceremony in August on Beatrice’s family-owned Borromean Islands in Italy. Beatrice‘s exquisite taste and journalistic prowess have cemented her status, with Tatler once crowning her the ‘most stylish European royal’. Pierre, beyond his royal duties, is known for his humanitarian efforts and his passion for competitive sailing and car racing.

Grace Kelly’s Enduring Legacy: A Hollywood Link to Royalty
The enduring fascination with Monaco’s royal family, particularly the descendants of Princess Grace Kelly, remains a cornerstone for classic film enthusiasts. Pierre Casiraghi‘s lineage directly connects him to his grandmother, the beloved Hollywood actress who famously married Prince Rainier III of Monaco in 1956. This real-life fairytale merger of Tinseltown glamour and European aristocracy continues to captivate the public imagination decades later.
Each new birth in this branch of the family, like that of Bianca Caroline Marta, serves as a poignant reminder of Grace Kelly‘s indelible mark on both cinematic history and royal tradition. Fans worldwide continue to follow the lives of her grandchildren, seeing in them echoes of the grace and charm that defined her.
The Succession and the Expanding Grimaldi Family Tree
The arrival of Bianca Caroline Marta places her as eleventh in the line of succession to the Monegasque throne, a position that highlights the continued growth and stability of the royal family. While her uncle, Prince Albert II, is the reigning monarch, the Casiraghi line plays a vital role in the future of the principality.
Princess Caroline, as the eldest child of Prince Rainier III and Grace Kelly, has seen her family expand significantly. Her other children, Andrea Casiraghi and Charlotte Casiraghi, also have growing families. Andrea and his wife Tatiana Santo Domingo welcomed their third child, Maximilian Rainier, just months before Francesco Casiraghi‘s birth in 2018. Maximilian joins older siblings Alexander “Sacha” and India. These numerous additions ensure the continuation of the Grimaldi dynasty, blending tradition with modern life.
