The Queen has a big family around her, with eight grandchildren and 12 great-grandchildren - but their roles in the family are very different.
Her most senior grandsons Prince William and Prince Harry took on senior positions due to their father Prince Charles being next in line for the throne, but those further down the line of succession can escape the royal spotlight.
The Queen's second youngest grandchild Lady Louise Windsor, who turned 18 last year, wasn't well known during her childhood, however has made a number of public appearances following the death Prince Philip.
