The third in line to the throne, who was born on Monday at St Mary’s Hospital in London, will officially be known as His Royal Highness Prince George of Cambridge.
The Queen was reportedly told of the little Prince’s name when she met him or the first time on Wednesday. Currently, the Cambridge family are visiting the Middleton home in Bucklebury, Berkshire, after spending a night at Kensington Palace.
George had been tipped by bookmakers’ as the favourite name in a pool that included other traditional royal names such as James, Spencer, and Henry.
There have been six King Georges to date, the most recent being the Queen’s father, although his first name was Albert and he was known to his loved ones as Bertie.
Louis is Prince William’s fourth name, most likely a tribute to Lord Louis Mountbatten, the Duke of Edinburgh’s uncle and also the last British Viceroy of India before independence in 1947.
Alexander was a favourite of Catherine’s, it is reported.
While having regal sentiment, George is also a saint’s name; St George is the patron saint of England.
Prince William has two weeks’ paternity leave before he is due back to work in Anglesey where he is an RAF search and rescue pilot.
