The birth of Prince Harry and Meghan Markle’s new baby, Archie Harrison Mountbatten-Windsor, last week marked a new addition to the next generation of royals who will one day take over running England’s centuries-old monarchy. Here’s the complete list of the next-gen royals arranged according to their ages.

James Alexander Philip Theo Mountbatten-Windsor (11 Years)

Born on Dec. 17, 2007, James, Viscount Severn, has the distinction of being Queen Elizabeth’s youngest grandson at the moment. He is the youngest child of Her Majesty’s youngest son, Prince Edward. This makes him Prince William and Harry’s first cousin.

While James has an older sister, Mike Tindall, husband of Zara Phillips (Princess Anne’s daughter), considers him to be the oldest member of this new and younger group of royals. “James is, well not exactly the ring leader, but he's the oldest,” Tindall told Telegraph. “So, yeah, it's going to be a good little group. And Harry, he's busy, but he loves playing with them all and he'll be a good dad.”

Savannah Anne Kathleen Phillips (8 Years)

Born on Dec. 29, 2010, Savannah Phillips is the daughter of Peter Phillips, who is the son of Princess Royal Anne. Savannah has the distinction of being Her Majesty’s eldest great-grandchild, as well as Princess Anne’s eldest grandchild.

Isla Elizabeth Phillips (7 Years)

Isla Elizabeth is Savannah’s younger sister. She was born March 29, 2012, making her a year and three months younger than Savannah.

Lena Elizabeth Tindall (10 Months)

Lena is Zara Phillips and Mike Tindall’s second child. She was born on June 18, 2018, which makes her more than four years older than her sister Mia Grace.

Archie Harrison Mountbatten-Windsor (8 Days)

Born on May 6, 2019, Baby Archie is the most recent addition to the royal family. He is Prince Harry and Meghan Markle’s first child and is currently the sixth in line to the throne after his father, who is fifth.

Mike Tindall believes that Prince Harry will be the perfect dad for Baby Archie since he had plenty of practice. “He’ll be a great dad,” Tindall said. “Obviously, he’s godfather to Lena, but we’ve got a great group of young ones in the family now,” he added.

Debbie Frank, astrologer of the late Princess Diana, predicted that Baby Archie is destined for greatness. “People are already talking about the possibility of him running for US President when he is older — and the stars say he could handle a role of that magnitude very easily,” Frank wrote on The Sun.
