The Duke and Duchess’s son will be known as His Royal Highness George of Cambridge – so what is the name’s royal heritage?
(German-born George I, the first Hanoverian king of Great Britain, took the throne in 1714)
And the new true-blue British prince has been named George Alexander Louis and will be known as His Royal Highness Prince George of Cambridge.
The name George has a humble meaning – farmer or earth worker – but it has a grand and long history in the British Monarchy.
Six King Georges have worn the crown.
He had been destined to never sit on the British throne, as 50 Roman Catholics were closer in line than him.
But they were excluded by a law restricting succession to Protestants only in 1701.
King George II was born and raised in Germany, like his father.
He became king in 1727 and was the last king to lead an army into battle – at the Battle of Dettingen in 1743.
King George III reigned for 60 years – longer than any other previous British monarchs.
He was different from previous sovereigns from the House of Hanover, as he was born in Britain and never even visited Hanover.
But military conflicts in Africa, the Americas and Asia darkened his time on the throne.
The first Prince George of Cambridge was a grandson of George III and the only son of Prince Adolphus Frederick, the 1st Duke of Cambridge.
Prince George of Cambridge was born in 1819. He refused an arranged marriage, instead falling in love with an marrying actress Sarah Louisa Fairbrother, who was said to be a classic beauty and a graceful dancer.
They married in 1847 when she was already the mother of two of his children and pregnant with his third.
But the Duke did not seek the sovereign’s approval and the marriage was never recognised , hence his children were not eligible to inherit royal titles.
Miss Fairbrother, who generated much scandal including having a portrait painted in which she showed off her bare legs, was ostracised by the royal family and never given a title. Instead, she became known by the nickname Mrs FitzGeorge and this surname was taken by George’s offspring.
Despite his marriage, George had a wandering eye and soon after he wed he took up with mistress Louisa Beauclerk, who remained his lover for more than 30 years.
He went on to become the 2nd Duke of Cambridge after his father’s death. The Duke was in the Army and served in the Crimean War. He was promoted to Commander-in-Chief in 1887 and an equestrian statue of him stands in the middle of London’s Whitehall. He was said to have been a disciplinarian, who believed Army promotions should be based on social connections rather than ability. He died in 1904.
