If you mean Queen Elizabeth 2. She does not technically have or use a surname. The family use the surname WINDSOR for such occasions as William and Harry's roles within the military. The Queen is descended from the House of Saxe-Coburg, but her predecessors chose to use the name Windsor after the First World War (1914-1918) to distance the Monarchy from their Germanic bloodlines.
Queen Elizabeth II became queen when her father King George VI died in 1952
Princess Elizabeth (as she was then) trained as a driver and motor mechanic.
No, it is Windsor
Her mother was also named Elizabeth. Before she married, her surname was Bowes-Lyon
There has never been a Queen Elizabeth III, apart from the fictional Queen Elizabeth III of Manticore.
Queen Elizabeth's surname was Windsor. Her family's surname was Saxe-Coburg-Gotha until 1917 when they changed it to Windsor to sound non-German (the British people were anti-German then as it was WWI). Members of the British Royal Family do not have surnames. They are the descendants of the house of Windsor but this is not the same as holding a surname. However, as you posted this Question in the "Elizabeth I" category I assume you mean the first Queen Elizabeth. Elizabeth I was a member of the House of Tudor but, as with Elizabeth II this does not constitute a surname
Elizabeth Tudor Queen Elizabeth the First was from the house of Tudor so her name would have been Elizabeth Tudor. The current Queen Elizabeth the Second is from the house of Windsor, so her name is Elizabeth Windsor.
Queen Elizabeth 2
queen elizabeth 3?
elizabeth the 1
As Elizabeth II was the daughter of King George VI, and as she chose her own name as her regnal name, her name before assuming the throne was, as it is after, Elizabeth Alexandra Mary. Do note that the Royal Family does not have a surname, thus that is her complete name.
No, Queen Elizabeth II is not dead.
