Mary I was born on 18 February 1516 and was Queen of England and Queen of Ireland from 19 July 1553 until her death. She was the eldest daughter of Henry Vlll by his first wife Catherine of Aragon.
Mary I was the first Queen Regnant (that is, a queen reigning in her own right rather than a queen through marriage to a king).
There were other Queens of England before Mary but they only had the title Queen because their husband was the King. They are know as the Queen consort (i.e. wife and consort of a reigning king).
Both Empress Matilda and Lady Jane Grey were both uncrowned queen regnants.
Empress Matilda , daughter of Henry I, was declared "Lady of the English" at Winchester in 1141. However, she was never crowned in her short reign.
Lady Jane Grey,
England's 'nine-days queen' was proclaimed Queen of England after the death of Edward VI on 6 July 1553, but again not officially crowned.
