Princess Eugenie's husband Jack Brooksbank is known only as Mr. Brooksbank in royal circles. He doesn't have a title from the Queen, who traditionally gives royal titles when certain family members get married.
In October 2018, Princess Eugenie and Jack exchanged vows at St. George's Chapel, the same wedding venue for Prince Harry and Meghan, who got married a few months before them. Prince Harry and Meghan were given the titles the Duke and Duchess of Sussex as Queen Elizabeth's wedding gift.
However, Princess Eugenie didn't get a new title after marrying Jack. Nor does her new husband has a royal title to his name. According to reports, Princess Eugenie was also given the option to use Brooksbank as her legal name. Apparently, the Queen decided this couple won't have a royal title because of Princess Eugenie's position in the line of the succession.
She is the currently the ninth in line to throne, following Prince Charles, her cousins -- Prince William and Harry, their kids - Prince George, Princess Charlotte, Prince Louis and Archie Harrison, her father -- Prince Andrew, and sister -- Princess Beatrice. If her cousins have more kids or if Princess Beatrice's produces an heir, then Princess Eugenie's position will go down.
The report also stated that Princess Eugenie and Jack are not working royals who are expected to carry out duties on behalf of Queen Elizabeth. The Brooksbank pair actually hold private jobs and earn their private income.
Princess Eugenie is the director of Hauser & Wirth, an art gallery. She supports various charities and this isn't technically her royal work but her advocacy. Jack, on the other hand, is the European manager of Casamigos Tequila owned by George Clooney. Jack worked hard to rise through the ranks to be a club manager and previously worked as bartender.
Before Princess Eugenie got married to Jack, there were speculations that Prince Andrew asked the Queen to give his daughters and his future sons-in-law royal titles. However, Prince Andrew released a statement to deny the speculations.
He said that his daughters are "modern working young women," who just happen to be part of the royal family. Nothing makes him happier than to see his daughters build their own careers but he appreciates that the public recognizes the princesses as the granddaughters of Queen Elizabeth.
In a palace circular detailing some royal family engagements, Princess Eugenie is actually officially identified as Princess Eugenie, Mrs. Jack Brooksbank.
