"According to genealogical sources, it has been suggested that Georgiana was a descendant of the Mary Boleyn line, which later became associated with the Spencers, famously recognized as the lineage of Princess Diana. Mary Boleyn, a distant ancestor of many notable figures including Winston Churchill, John Davison Rockefeller, P. G. Wodehouse, Elizabeth Bowes-Lyon (the late Queen Mother and consequently the Queen), Diana, Princess of Wales, Sarah, Duchess of York, Charles Darwin, and Thomas West, 3rd Baron De La Warr, is known to have left an enduring legacy. Interestingly, the reported familial connection between Princess Diana and Sarah Ferguson, predating their respective marriages into the royal family, can be traced back to their shared ancestor, Georgiana, Duchess of Devonshire, who was born a Spencer, just like Diana. This kinship made them fourth cousins, as highlighted in an article by Express."
