No she was born Elizabeth of York. The monarch can pick what name name they'll reign under. Queen Elizabeth's father King George VI's given name was Albert. He was known in the family as Bertie. There have only been a handful of British queens. As such, QE2 could only choose from Elizabeth, Victoria and Mary (or maybe one of wives). Actually she could have chosen anything, I guess. But the Brits are known for their devotion to tradition. It's also been rumored that Charles may stay with Charles but Charles I and II were dubious kings. In the end only he know what he'll choose or not.Did Elizabeth change her name? I never knew that they change their names, must find out more!
