On the Middleton side, we have Carole, a former flight attendant who, with her hubby, achieved millionaire status through a mail-order party supply venture. (Perhaps her biggest scandal so far? Chewing nicotine gum during Prince William's graduation ceremony in 2006.) On the Windsor side, however, sits a legend on a cloud: none other than Diana, the near-sainted lady who married Prince Charles, divorced him, raised two sons, championed humanitarian causes like AIDS and land mines, and died in a tragic car crash at age 36.
