As he was the child of a morganatic marriage, Prince Henry of Battenberg took his style of "Prince of Battenberg" from his mother, Countess Julia Hauke, who was created Princess of Battenberg in her own right. As such, Maurice was styled as "His Serene Highness" Prince Maurice of Battenberg from birth. In the United Kingdom, he was styled "His Highness" Prince Maurice of Battenberg under a Royal Warrant passed by Queen Victoria in 1886. He was baptised in the Drawing Room at Balmoral on 31 October 1891. His godparents were the Duchess of Connaught and Strathearn (represented by Queen Victoria), the Princess of Leiningen (represented by Princess Christian of Schleswig-Holstein), the Duke of Clarence and Avondale (represented by Sir Henry Ponsonby), Prince Francis Joseph of Battenberg (represented by Sir Fleetwood Edwards) and the Hereditary Grand Duke of Hesse.
