"They're just a natural, normal family like the rest of the people that come in here, down to earth, lovely family, very polite, very nice," John Haley, the landlord at the local pub, the Old Boot told ABC.
At 29, she is university-educated, the first to marry a future king and to hold a degree. She met Prince William, who is 28, during their days at St. Andrews University in Scotland.
They have known each other well, first as friends, then living together. Their courtship has lasted nine years, which is why the tabloid press gave the bride the nickname, "Waitie Katie."
Still, Diana had an independent streak that echoes through many of Middleton's lifestyle choices.
Middleton, like her late mother-in-law, has made it clear she's "of the people," sighted in recent days on the High Street buying a dress from Banana Republic.
And William may have seen in Middleton the sense of flair that his mother exhibited -- not only in fashion, but in her joie de vivre.
Both wore feathers in their caps and were often seen in red and black with hats to match. They loved red polka dots and nights on the town. Diana took her boys skiing in the Alps, not unlike the new royal couple.
But while Diana and Charles accepted 6,000 gifts on their wedding day 30 years ago, the new royal couple has asked for donations to charity.
Just like his mother, William has remembered the Child Bereavement Charity, asking that invitees donate instead of sending gifts.
The gesture is bittersweet: The charity reaches out to children who have a lost a parent.
Said Prince William in 2009, when he became a royal patron to the charity, "What my mother recognized then -- and what I understand now -- is that losing a close family member is one of the hardest experiences that anyone can ever endure...Never being able to say the word 'mummy' again in your life."
