The locals in her hometown of Bucklebury say they are thrilled that Middleton has found love within the royal family.
"Absolute magic," local butcher Martin Fiddler said of the news. "A long time in the coming. We are so happy."
Though no blue bloods, Middleton's parents Michael and Carole have made a comfortable living for themselves and their two children. They live in a modest, five-bedroom house in the countryside and their online supply company is said to have made them millions.
And just as the royal family appears smitten with their daughter, the Middletons have embraced the future king of England as their son-in-law.
''As you know Catherine and Prince William have been going out together for quite a number of years which is great for us because we got to know William really well," Michael Middleton said. "We all think he's wonderful and we're extremely fond of him.''
William, likewise, said he has found Middleton's family to be welcoming.
"I get on really well with them and I'm very lucky that they've been so supportive," William said Tuesday. "Mike and Carole have been really loving and caring and really fun and have been really welcoming towards me so I've felt really a part of the family."
