This decision could have been connected to the name (and reputation) of upscale Mayfair club Annabel's, a favourite haunt of Andrew, Fergie and other young members of the royal family.
Ironically, Princess Beatrice has been a regular at Annabel's for many years now, and was recently photographed leaving after hours venue with her mum and new boyfriend, Edoardo Mapelli Mozzi.
Flame haired Fergie was branded a "minor social revolutionary" by H.B. Brooks-Baker who also noted the York's decision to use just two middle names instead of the usual three or four given to children of the House of Windsor.
Princess Beatrice's full title is Beatrice Elizabeth Mary, given to her in honour of her ancestor Queen Victoria's youngest child.
Prince Charles, in comparison, was given the full name Charles Philip Arthur George.
Beatrice's youngest sister Princess Eugenie - full name Eugenie Victoria Helena - was also named after the legendary Queen Victoria.
Her first name honours Victoria Eugenie of Battenberg, Queen Victoria's granddaughter, while her middle name comes from Princess Helena, Queen Victoria's daughter.
With just one year's age difference between them, Princesses of York enjoy a famously close bond.
Earlier this week, the royal sisters were spotted on a double date in London's Notting Hill with Eugenie's new husband Jack Brooksbank and Bea's beau Edo.
Eugenie, 29, married Jack in a fairytale royal wedding in October at St George's Chapel at Windsor Castle.
