Princess Beatrice and her husband Edoardo Mapelli Mozzi are celebrating their daughter Sienna's third birthday. Sienna, tenth in line to the British throne, will not receive a royal title from her mother's side but inherits the title of 'Nobile Donna' and 'contessa' from her father, an Italian count. The couple has made efforts to keep Sienna's life private, sharing only a few photos. Sienna's name pays homage to her father’s Italian heritage and her grandmother Sarah Ferguson. Her middle name, Elizabeth, honors Beatrice's grandmother, Queen Elizabeth II. The royal family and close friends praise Beatrice for her natural affinity for motherhood and her strong bond with her daughter.
