The Queen has a massive family with eight grandchildren and 12 great-grandchildren, but all their roles are extremely different.
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 stay out of the royal spotlight.
According to The Mirror, The Queen's second youngest grandchild Lady Louise Windsor, who turned 18 last year, wasn't really known during her childhood, however she has been seen regularly now following the death Prince Philip.
And while her older cousins William, Harry, Beatrice and Eugenie all hold titles of Prince and Princess, Louise doesn't hold the title of Princess, MyLondon reports.
She's the daughter of the Queen and Philip's youngest son, Prince Edward, and his wife Sophie the Countess of Wessex. She has a younger brother, James, who also doesn't have a HRH title.
Meanwhile, her cousins Peter Phillips and Zara Tindall - children of Anne, Princess Royal, and Captain Mark Phillips - are not automatically eligible for the title.
The reason behind Louise and her brother James not carrying the title dates back to her parents' wedding day in 1999, when they were bestowed with the titles the Earl and Countess of Wessex, much to the surprise of royal fans.
The decision broke centuries of tradition, however Buckingham Palace explained the plan was for Edward to be created Duke of Edinburgh upon both the death of his father and accession of elder brother.
After Lady Louise's birthday in November, she had the right to make her own decision about whether she wanted a title and could opt to become Princess if she wishes - but her mum says that's unlikely.
In 2020, the Countess of Wessex told The Sunday Times: "We try to educate them with the understanding that they will most likely have to work for a living. That is why we made the decision not to use HRH titles. They have them and can decide to use them after 18, but I think it is very unlikely."
During an earlier interview for the Queen’s 90th birthday in 2016, Sophie joked about Louise's realisation that her grandmother was the Queen.
"I mean Louise had no concept really that the Queen and her grandmother were one and the same person," she told Sky News.
"It wasn’t until she was at school that other children were mentioning it and saying, 'Your gran is the Queen'. And she'd come home and say, 'Mummy, they say that Grandmama is the Queen.' And I said, 'Yes,' and she said, 'I don’t understand what they mean.'"
