The Duke of Sussex celebrated his birthday last week and while many of the cards no doubt will have carried the name 'Harry', this isn't actually his real name.
When Harry returns to the UK later this month, his passport will actually carry the name 'Henry'. When he was christened in 1984, his full name was Henry Charles Albert David. Despite this, Harry's parents, the then Prince Charles and Princess Diana shared that the youngster would go through life being called Harry.
It is by tradition that royal names are ones that have been in the family for generations. Henry was a very popular name back in the Tudor times, with one of the most notable carriers of the moniker being King Henry VIII.
However, Henry was only used by the parents, and it was only used when the young royal would get himself into trouble.

Harry had another 'H' nickname from his family, with his brother often calling him 'Harold'.

Albert also holds a different significance for Harry, as the royal's father originally wanted to name his youngest child this, in honour of his late grandfather, King George VI, who was christened as Albert Frederick Arthur George.
