Kate Middleton's cancer diagnosis was just one challenge she and Prince William had to face together in recent years.

Kate Middleton has opened up about why she and her husband, Prince William, moved their family to Windsor. While attending the Irish Guards' parade at Wellington Barracks as part of the St. Patrick's Day celebrations, the Princess of Wales was reportedly asked where the royals currently reside.

The Princess of Wales not only wore a subtle tribute to her daughter on St. Patrick’s Day, but she brought her up in conversation.
