Seven years ago, before this blog officially began, a letter was published in the Ricardian Bulletin about the common Edward III descent of the Duke and Duchess, as she soon became, of Cambridge through the Gascoigne-Fairfax line. This, about the Duke and Duchess of Sussex’s mutual ancestry, followed this March.
Now it is clear that Princess Eugenie, the former scoliosis sufferer and daughter of the Duke of York, and her partner Jack Brooksbank are closely related through Edward III and James II (the Scottish one). They will marry at St. George’s Chapel, Windsor on 12 October.
Having examined the evidence, this document and shows that they have a most recent common ancestor: Thomas Coke, 2nd Earl of Leicester (1822-1909).
Coke’s simplest royal descent is from Charles II.
Brooksbank is descended from Edward III via Robert Devereux (2nd Earl of Essex, through four of Edward III’s sons, although I have chosen the senior Mortimer line) to Coke’s second wife, Lady Georgiana Cavendish, although there is probably other Edward III ancestry. Lady Georgina’s grandmother was Lady Catherine Gordon, daughter of the Marquess of Huntly and this line descends from James IV, who is obviously more recent than his grandfather, but through his mistress not his “Tudor” wife. He, of course, was James II’s grandson.
Furthermore, as this picture shows, Princess Eugenie wore a backless dress to show her scoliosis scar.
