It comes from Queen Elizabeth I, the "virgin" queen, of England.
When Elizabeth II was a small girl, Queen Elizabeth the Queen Mother called her 'Lillibet'.
She was an England queen who died in 1603. On this date the "Great Britian" began to call itself "United Kingdom".
Because English settlers moved over there and named a majority if the states eg. Virginia is named after queen Elizabeth 1. The virgin queen .
No elizabeth did not have children she was what some people call her 'The Virgin Queen'
Mary Stewart, Queen of Scotland's cousin Elizabeth I of England never had a baby. That is why Elizabeth was known as the 'Virgin Queen'. Elizabeth I was never married and never had a child so she did not call her baby anything because it did not exist.

Lilibet.
The parents of Queen Elizabeth II were King George VI and Queen Elizabeth (formerly Elizabeth Bowes-Lyon). When the King passed away, his daughter succeeded to the throne and became Elizabeth II in 1952. Her mother then stepped aside and became the Queen Mother. (Elizabeth I reigned in the 17th Century - The Queen Mother was NOT Elizabeth I.)

Elizabeth I was never referred to as the Pirate Queen. That title was given to Grace O'Malley of Ireland, a notorious woman pirate who lived during Elizabeth's reign.
In formal circumstances, "Your Majesty". I do not what she is called by them in private.
