Your Guide to Every Single Member of the British Royal Family

Despite being the daughter or the royal "spare," Queen Elizabeth II became second in line for the throne after her uncle, King Edward VIII, abdicated the throne in 1936, and therefore her father, King George VI, took over as reigning monarch in 1937. In 1952, when her father passed away, she inherited the throne and was officially sworn in at the age of 27 on June 2, 1953.

Queen Elizabeth II has been married to Prince Philip since 1947 and has been the reigning monarch for more than 60 years. Clearly, the queen knows how to make both her love life and her career work for decades upon decades.

Together, the Queen and Prince Philip have four children, Prince Charles, Princess Anne, Prince Andrew, and Prince Edward. While Queen Elizabeth II has been in charge of the United Kingdom for more than half a century, she will most likely hand over the crown to her eldest son, Prince Charles, within the next few years.

As the eldest child of Queen Elizabeth II and Prince Philip, Prince Charles (or Charles, Prince of Wales) is the next in line for the throne. When his mother, who is the longest-reigning monarch in the country's history, does decided to step down, or passes away, he will be the rightful ruler of the UK.

As you probably already know, Prince Charles has two children, Prince William and Prince Harry, with his late ex-wife, Princess Diana. After the two divorced in 1996, he found love again with Camilla, now Duchess of Cornwall, whom he wed in 2005.

Now, for the royal family who continually catches our attention: the Duke and Duchess of Cambridge and their adorable children! Prince William is the first born son (and child) of Prince Charles and Princess Diana and is therefore second in line for the throne, behind his father.

In 2011, Prince William married Kate Middleton, and they assumed the titles of the Duke and Duchess of Cambridge. In 2013, the couple had their first child, a son named Prince George of Cambridge, who is third in line for the throne. His little sister, Princess Charlotte of Cambridge, who was born in 2015, is fourth in line.

The good news is that although it's unlikely that Princess Charlotte would become the next queen — her brother or father or both would have to abdicate the throne for her to inherit it — based on the new Succession to the Crown Act, which was changed in 2013, then put into place in 2015, she can become queen, no matter what, even if her mother, who is currently pregnant with baby number three, has another boy. In the past, all male heirs would jump their sisters in line for the throne, but Princess Charlotte's younger sibling won't be able to do that, and that's a big deal.

Here's where things get a little tricky. Prince Andrew, the second son, but third child of Queen Elizabeth II and Prince Philip is sixth in line for the throne. His daughters, whom he had with his now ex-wife, Sarah Ferguson, Princess Beatrice of York (on the right), born in 1988, and Princess Eugenie of York (on the left), born in 1990, are seventh and eighth in line respectively.

While that seems pretty straightforward, it's actually totally messed up, because Prince Andrew, Duke of York, is actually the third child from the current monarch. Since the second born is a girl, Princess Anne, the throne skipped over her (it was all about male heirs back in the day) and went to Prince Andrew after the eldest, Prince Charles. Luckily, that is no longer the rule, but tough break for the females in the royal family before 2013, right?

Princess Anne, the Princess Royal was born in 1950 and is the second child of the ruling queen and her husband. In 1973, Princess Anne married Captain Mark Phillips, and together they had two children, before getting divorced in 1992. The Princess Royal comes in at the 12th spot in line, and her children follow — her son comes first (this time he is the oldest).

Peter Phillips is 13th in line for the throne, and thanks to his lovely wife, Autumn Kelly Phillips, their two daughters, Savanah, and Isla, come in at 14th and 15th. The 16th spot in the long line of people who can become monarch is held by Peter's younger sister, Zara Phillips Tindall.

Zara is a professional equestrian (she is on the left in the photo) and is married to Mike Tindall. They have one daughter, Mia (who is also in the photo above), born in 2014, who is 17th in line to be queen. This is where Queen Elizabeth II's direct descendants end in the line of succession ... at least for now!

Next comes David Armstrong-Jones, the second Earl of Snowdon, who is the eldest child of Princess Margaret, who was Queen Elizabeth II's younger sister. He is 18th in line for the throne, followed by his children.

His son, Charles Armstrong-Jones, Viscount Linley, who was born in 1999, is number 19, followed by his daughter, Lady Margarita Armstrong-Jones (photographed here with her father and grandaunt), born in 2002, who comes in at number 20.

This is where things start to get a little crazier! Prince Richard, Duke of Gloucester, is the cousin to Queen Elizabeth II (on her paternal side), and son of the late Prince Henry, Duke of Gloucester. He is married to Birgitte, Duchess of Gloucester, and 24th in line for the throne.

The Duke of Gloucester is actually a pretty hands-on royal and is described as a full-time working member of the Royal Family on its official website. He attends public events both nationally and internationally and is associated with more than 150 charities.

Prince Richard has three children, a son and two daughters. His eldest son is Alexander Windsor, Earl of Ulster, who is 25th in line for the throne followed by his two children, Xan Windsor or Lord Culloden at 26, and Lady Cosima Windsor at 27. Prince Richard's middle child is Lady Davina Lewis, who is 28th in line, followed by her two children, Senna Lewis at 29 and Tane Lewis at 30. Her younger sister and Prince Richard's youngest daughter, Lady Rose Gilman, is 31st in line for the crown and also has two children, Lyla Gilman (number 32) and Rufus Gilman (number 33).

Prince Michael of Kent (far right in the photo above) is another first cousin to the Queen (and brother to Prince Edward, Duke of Kent). When he was born, he was eighth in line for the throne, according to his official website, but now sits at spot 45.

He married Baroness Marie-Christine von Reibnitz in 1978 and lost his right of succession because the now-princess is a Roman Catholic. He was later given back his right of succession, thanks to the Succession Act of 2013, which says if you marry a Catholic you can keep your spot in line and your title.

The couple has two children: their eldest son, Lord Frederick Windsor, is 46th in line for the throne and his two children, Maud Windsor and Isabella Windsor, come in line after him (at number 47 and 48). Prince Michael's second child, Lady Gabriella Windsor is 49th on the royal family tree.
