July 23, 2013 - 19:02 BST hellomagazine.com Prince William and Kate Middleton name royal baby George Alexander Louis: He will be known as His Royal Highness Prince George of Cambridge Prince William and Kate Middleton have given their royal baby the name George Alexander Louis. "The Duke and Duchess of Cambridge are delighted to announce that they have named their son George Alexander Louis," read a statement from Kensington Palace. "The baby will be known as His Royal Highness Prince George of Cambridge." Earlier this month, Buckingham Palace made an official announcement that Prince William and Kate's first born would hold the official title of His or Her Royal Highness Prince or Princess of Cambridge, following his own parents' title of the Duke and Duchess of Cambridge. The couple's baby boy is not the first Prince George of Cambridge though. Prince George of Cambridge, born in 1819, was the colourful grandson of King George III, and also held the title. He outraged his cousin Queen Victoria by marrying without her consent and having several illegitimate children. His father was Adolphus, Duke of Cambridge, the seventh of the King's sons, while his mother was Princess Augusta of Hesse-Cassel. The couple also had two girls Princesses Mary and Augusta of Cambridge. On his father's death in 1850 George inherited the dukedom. He is related to the current Queen through his sister Mary. Her daughter was Queen Mary, who married George V and became Queen Elizabeth II's grandmother. On Prince George of Cambridge's death in 1904, the title became extinct since he had no legitimate heirs. It was revived in 2011 when his sister's great-great-great-grandson William was created Duke of Cambridge on his wedding day by the Queen.
