Princess Eugenie of York and her husband Jack Brooksbank welcomed their first child, a baby boy, on February 9.

The new royal baby is Queen Elizabeth's ninth great-grandchild and Prince Andrew and Sarah Ferguson's first grandchild.

Eugenie's son has not been added to the line of succession on the royal family website, likely because he does not yet have a name. However, the little one is expected to be named 11th in line to the throne since his mother is 10th in line.

This will push back the Queen's youngest son Prince Edward to the 12th in line, and his children Viscount Severn and Lady Louise Mountbatten-Windsor, will be pushed back to the 13th and 14th inline, respectively.

This also means that the Queen's daughter Princess Anne will move from 14th to 15th place in the line of succession.

The Queen's eldest son Prince Charles is currently first in line to the throne, followed by Prince William (second) and his children, Prince George (third), Princess Charlotte (fourth), and Prince Louis (fifth). Prince Harry is sixth in line, followed by his son Archie Harrison Mountbatten-Windsor.

The royal baby won't affect Prince William's children and Prince Harry's children, who were born ahead of Eugenie in the line of succession.

It's likely the baby won't have a royal title due to a letters patent issued by King George V in 1917, which limited the titles of prince and princess to: "The grandchildren of the sons of any such Sovereign in the direct male line (save only the eldest living son of the eldest son of the Prince of Wales)."

While there are other titles royal babies can inherit, Eugenie's baby won't be given one because they can usually only be passed down through the male line.

"If the baby's father does not have a title, then there is no chance that he or she will have one," Joe Little, managing editor of Majesty magazine, previously told Insider.
