His death in RAF service marked the first time in more than 450 years that a member of the royal family died on active service. The prince's body was transferred initially to St. George's Chapel, Windsor, and he was buried in the Royal Burial Ground, Frogmore, directly behind Queen Victorias mausoleum. His elder son, six-year-old Prince Edward, succeeded him as Duke of Kent. Princess Marina, his wife, had given birth to their third child, Prince Michael, only seven weeks before Prince George's death.
