Princess Eugenie of York and her husband Jack Brooksbank have named their new baby August Philip Hawke Brooksbank.

The couple announced the name of their first child via Instagram, alongside a family photo.

"We wanted to introduce you to August Philip Hawke Brooksbank," Eugenie wrote on Instagram. "Thank you for so many wonderful messages. Our hearts are full of love for this little human, words can't express. We are excited to be able to share these photos with you.⁣"

The princess also noted that the picture was taken by her midwife, and she thanked the "wonderful essential workers including our midwife who came to discharge our boy."

The names "August" and "Hawke" appear to be un-traditional choices, while "Philip" was likely chosen after Eugenie's grandfather, Prince Philip.

The 99-year-old royal is currently being treated in the hospital in London as a "precautionary measure" after feeling unwell earlier this week.

Eugenie and Brooksbank welcomed the baby on February 9.

The couple have been together for 10 years, and were married at St George's Chapel in Windsor on October 12, 2018.

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

The arrival of Eugenie's first child has shifted the line of succession.

August was born 11th in line to the throne, pushing back several other royals - including two of the Queen's children, Prince Edward and Princess Anne - in the line of succession.

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