The Duke and Duchess of Cambridge's only daughter was born in May 2015 and her full name was confirmed as Princess Charlotte Elizabeth Diana, with her middle names in honour of Her Majesty and Princess Diana.

Anne's full name is Anne Elizabeth Alice Louise, while her daughter is Zara Anne Elizabeth Tindall. Zara and her husband Mike Tindall in turn chose to name their second daughter Lena Elizabeth.
Prince Andrew and Sarah, Duchess of York's firstborn daughter is Princess Beatrice Elizabeth Mary. Likewise, Prince Edward and the Countess of Wessex's daughter is Lady Louise Alice Elizabeth Mary.
