Prince Harry and Meghan Markle just welcomed their first son.

Following the birth of Baby Sussex, royal fans couldn’t help but wonder how the newest addition to the royal family would fit in the order of succession. On the online forum site Quora, one royal fan asked if the order of succession would change in favor of Markle and Prince Harry’s son if none of Prince William and Kate Middleton’s three children would get married.

Eileen Wood, a real estate assistant, said that the order of succession won’t change regardless if Prince George, Princess Charlotte, and Prince Louis would tie the knot or not. The only time Baby Sussex could become king is if Prince Harry would die before all of Prince William’s children.

And assuming that both Prince Charles and Prince William have already passed on, Prince George would become king. If he is not married and doesn’t have children, Princess Charlotte would continue to come after him in the order of succession. If something happens to Prince George, Princess Charlotte would be crowned king.

The same thing would happen if Princess Charlotte, who is unmarried, dies before Prince Louis. The youngest child of the Duke and Duchess of Cambridge would then become king. And if all three of their children pass away before Prince Harry and Markle’s son, that’s the only time Baby Sussex could become King.

“If Baby Sussex dies childless and has no siblings, Prince Andrew becomes King. The crown would then pass to Princess Beatrice on his death or if he predeceased Baby Sussex,” she wrote.

However, Wood also said that the likelihood of Prince George, Princess Charlotte, and Prince Louis dying early is very small.

Prince Harry and Markle just welcomed their firstborn on May 6. The Duke of Sussex made the announcement just hours after Markle gave birth. The proud dad also told reporters that they would get to see Markle and their son for the first time sometime this week.
