The short answer? Probably not.
Traditionally, royals are granted titles on their wedding days by the monarch, Eugenie's grandmother Queen Elizabeth. Prince Harry received a dukedom on his wedding day to Meghan Markle in May 2018, officially making them the Duke and Duchess of Sussex. Similarly, Prince William and Kate Middleton were named the Duke and Duchess of Cambridge upon their 2011 wedding.
When Princess Eugenie and Jack tied the knot in 2018, they did not receive any new titles. Jack is simply known as "Mr. Brooksbank," while Eugenie has stylized her name as "Princess Eugenie, Mrs. Jack Brooksbank" since the nuptials.

Despite being a member of the royal family — and Queen Elizabeth's great-grandchild — Princess Eugenie and Jack's son or daughter will likely earn his or her own income.
In addition to appearing alongside her family at royal events like Trooping the Colour and supporting charitable causes, Eugenie works as a director at the London art gallery Hauser & Wirth. Meanwhile, Jack works with George Clooney-founded tequila business Casamigos, which the actor sold in 2017.
When Meghan and Prince Harry welcomed son Archie in May 2019, he did not receive a royal title.

Sophie, Countess of Wessex recently discussed her own children's future. Lady Louise, 16, and James, Viscount Severn, 12, are grandchildren of Queen Elizabeth but are unlikely to use their Her/His Royal Highness titles when they are adults, Sophie revealed.
"We try to bring them up with the understanding that they are very likely to have to work for a living,” the wife of Prince Edward told The Sunday Times. "Hence we made the decision not to use HRH [His/Her Royal Highness] titles. They have them and can decide to use them from 18, but it’s highly unlikely."
