Prince William (Photo: REUTERS)Prince William reportedly pushed back against an alleged proposal from King Charles III to change the spelling of Kate Middleton's first name before she officially joined the Royal Family, according to claims in a royal biography that has resurfaced online. Neither Buckingham Palace nor Kensington Palace has commented on Andersen's account, and the allegations have not been independently verified. According to Andersen's biography, the discussion took place when Charles and Queen Camilla were still the Prince of Wales and Duchess of Cornwall. One source quoted in the biography claims William believed changing Kate's name was "completely unacceptable." Another insider claimed the Prince of Wales believed asking Catherine to reshape part of her identity "was a step too far."
