Princess Beatrice, 33, and Edoardo Mapelli Mozzi, 38, welcomed daughter Sienna to the Royal Family back in September. Young Sienna, the couple's first child, weighed some 6 pounds and 2 ounces when she was born at the Chelsea & Westminster Hospital.

       However, some people might not know Beatrice and Edoardo share a childhood connection.

       Prince Andrew, 61, and Sarah Ferguson, 62, welcomed their eldest daughter to the Firm at Portland Hospital in London on August 8, 1988.

       But just five years earlier, on November 19, future husband Edo was born at the very same hospital.

       The chief executive of Banda Property is the son of British Olympian and member of the Italian nobility Alessandro Mapelli Mozzi, 70.

       The Anglo-Italian competed for Great Britain at the 1972 Winter Olympics held in the Japanese city of Sapporo as an alpine skier.

       Edo's mother is Nicola Williams-Ellis MBE.

       According to Alessandro, Sienna's Italian heritage has bestowed on her a title.

       Speaking to the Daily Mail, he said: "Edoardo is the only male descendent taking the family into the next generation.

       "He is a count, his wife will be a countess automatically and any of their children will be counts or nobile donna."

       Edoardo was educated at the Oxfordshire independent school Radley College, which is around 50miles away from Beatrice's former school St George's in Ascot.

       The pair both went on to attend university.

       Edoardo enrolled at Edinburgh to read politics, whereas Beatrice studied history and the history of ideas at Goldsmiths in London.

       However, Beatrice and Edo are not the only members of the Royal Family to be born at Portland Hospital.

       Beatrice's sister Eugenie, 31, was born at the prestigious London hospital in 1990 as was Archie Mountbatten-Windsor, two, in 2019.

       While Beatrice and Edo's daughter Sienna was not born at the same hospital, sister Eugenie and her husband Jack Brooksbank, 35, opted to welcome son August to the world at Portland last February.
