The Queen has welcomed four new additions to her family this year, with her granddaughter Princess Beatrice giving birth to her first child Sienna in September.
And some of her great-grandchildren share a special connection with Her Majesty and her late husband, the Duke of Edinburgh.
Princess Beatrice and Edoardo Mapelli Mozzi revealed their daughter's full name almost two weeks after her birth, calling her Sienna Elizabeth Mapelli Mozzi, in a sweet nod to the Queen.

The couple's second child is Lena Elizabeth Tindall and her middle name pays homage to the Queen.
