In the early morning hours of Monday, October 15, Kensington Palace released an official statement that "Their Royal Highnesses The Duke and Duchess of Sussex are very pleased to announce that The Duchess of Sussex is expecting a baby in the Spring of 2019." Their child will become seventh in line to throne—just behind his or her dad, who has been pushed down the line in recent years with the arrival of Princes George and Louis and Princess Charlotte. But William's children and Harry's baby-to-be aren't the only pint-sized descendants of Queen Elizabeth II to be born in the past 20 years. Here are 21 more of them.

1. ARTHUR CHATTO

Arthur Robert Nathaniel Chatto, who turned 19 years old February 5, is the younger son of Lady Sarah and Daniel Chatto. He is 24th in the line of succession—and has been raising some royal eyebrows with his penchant for Instagram selfies.

2. CHARLES ARMSTRONG-JONES, VISCOUNT LINLEY

The grandson of Lord Snowden and Princess Margaret, and son of the 2nd Earl and Countess of Snowdon, Charles—who was born on July 1, 1999—is the heir apparent to the Earldom of Snowdon.

3. LADY MARGARITA ARMSTRONG-JONES

Born on May 14, 2002, Lady Margarita is sister to Charles Armstrong-Jones, and great-niece to the Queen. She's 21st in line to the throne.

4. LADY LOUISE WINDSOR

Lady Louise Windsor is the eldest child and only daughter of Prince Edward, Earl of Wessex, and Sophie, Countess of Wessex. She was born on November 8, 2003 and is 12th in line for the throne.

5. ELOISE TAYLOR

The third child of Lady Helen and Timothy Taylor, Eloise Olivia Katherine Taylor was born on March 2, 2003 and is 46th in line for the throne.

Eloise's younger sister, Estella Olga Elizabeth Taylor, was born on December 21, 2004. She is the youngest of the four Taylor children and is 47th in succession.

7. JAMES, VISCOUNT SEVERN

The younger child of Prince Edward, Earl of Wessex, and Sophie, Countess of Wessex, James Alexander Philip Theo Mountbatten-Windsor—or Viscount Severn—was born on December 17, 2007 and is 11th in line for the throne.

8. ALBERT WINDSOR

Albert Louis Philip Edward Windsor, born September 22, 2007, is notable for being the first royal baby to be baptized a Catholic since 1688. He is the son of Lord and Lady Nicholas Windsor, and grandson of the Duke and Duchess of Kent. According to the Act of Settlement, which was passed in 1701, being baptized Catholic would automatically exclude a potential royal from the line of succession. But there was some controversy surrounding this when, up until 2015, the Royal Family website included Albert.

9. XAN WINDSOR

Lord Culloden, Xan Richard Anders Windsor, is son to the Earl of Ulster and Claire Booth, and grandson of the Duke of Gloucester. He was born on March 2, 2007 and is 28th in succession.

10. LEOPOLD WINDSOR

Like his older brother Albert, Leopold Windsor—who was born on September 8, 2009—is not in line to the throne, by virtue of being baptized a Roman Catholic (though he, too, was listed on the Royal Family's website for a time).

11. SAVANNAH PHILLIPS

Savannah Anne Kathleen Phillips, the Queen's first great-grandchild, was born on December 29, 2010 to Peter Phillips, son of Princess Anne and Mark Phillips, and Autumn Kelly. She is 15th in line for the throne.

12. SENNA LEWIS

Senna Kowhai Lewis, who was born on June 2, 2010, is the daughter of Gary and Lady Davina Lewis, elder daughter of Prince Richard, Duke of Gloucester. She was a beneficiary of the Succession to the Crown Act 2013, which abolished the practice of giving sons precedence over daughters in the line of succession, regardless of when they are born. As a result, she is 31st in succession.

13. LYLA GILMAN

Daughter of Lady Rose and George Gilman, and granddaughter of Prince Richard, 2nd Duke of Gloucester, Lyla Beatrix Christabel Gilman was born on May 30, 2010. She is 34nd in succession.

14. COSIMA WINDSOR

Lady Cosima Rose Alexandra Windsor was born on May 20, 2010. She is sister to Lord Culloden, daughter of the Earl of Ulster and Claire Booth, and granddaughter to the Duke of Gloucester. She's 29th in line for the throne.

15. RUFUS GILMAN

Lyla Gilman's brother, Rufus, born in October 2012, is 35rd in line for the throne.

16. TĀNE LEWIS

Tāne Mahuta Lewis, Senna's brother, was named after a giant kauri tree in the Waipoua Forest of the Northland region of New Zealand. He was born on May 25, 2012 and is 32nd in line for the throne, following the Succession to the Crown Act 2013.

17. ISLA PHILLIPS

Peter and Autumn Phillips's second and youngest daughter, Isla Elizabeth Phillips, was born on March 29, 2012 and is 16th in succession.

18. MAUD WINDSOR

Maud Elizabeth Daphne Marina Windsor, the daughter of Lord Frederick and Lady Sophie of Windsor and granddaughter of Prince and Princess Michael of Kent, was born on August 15, 2013 and is 50th in line for the throne.

19. LOUIS WINDSOR

Louis Arthur Nicholas Felix Windsor, who was born on May 27, 2014, is the youngest child of Lord and Lady Nicholas Windsor, and brother of Leopold and Albert. As he was baptized into the Roman Catholic church, he's not in line to the throne.

20. MIA GRACE TINDALL

Daughter of Zara Phillips and her husband, former England rugby player Mike Tindall, Mia Grace Tindall was born on January 17, 2014 and is 18th in the line of succession.

21. ISABELLA WINDSOR

Isabella Alexandra May, the second and youngest daughter of Lord Frederick and Lady Sophie of Windsor, was the last addition to the royal family. In July 2016, she was christened at Kensington Palace wearing the same gown worn by both Prince George and Princess Charlotte (it's a replica of the one that Queen Victoria's children wore). Looking on was celebrity chef Jamie Oliver, who is one of Isabella's godparents.
