She might be a commoner, but the royal family accepted Kate Middleton with open arms. Queen Elizabeth II herself was even happy when Prince William decided to marry the Duchess of Cambridge in 2011. With her excellent upbringing and strong relationship with her family, Kate, along with her parents, Michael and Carole Middleton, managed to give the Duke of Cambridge a happy, ordinary life after Princess Diana's demise.

Kate Middleton has a strong and stable family upbringing that are believed to be the fundamentals of her ability to cope up with the pressures of the royal life. Although she has a simpler background compared to other royals, she has a firmer and more secure foundation.

According to Express, the devotion of Kate's family attracted Prince William more when they met at St. Andrews University. Royal expert Ingrid Seward claimed that the Middletons managed to give the second heir to the throne an ordinary family life, which he lacked since Princess Diana died.

They let him experience a life not being pressured of having several appointments and engagement, like what Prince Charles did. In fact, when Prince William and Kate got married in 2011, he started to spend more time with the Middletons than he did with his own father. He also began to call his father-in-law "dad."

The royal family never let it go unnoticed. As Kate Middleton is at the top of her game and able to live up to all the expectations and devote herself to the firm, Queen Elizabeth and her husband, Prince Philip, gladly accepted the Middletons.

Of all the in-laws Queen Elizabeth has, The Sun noted that the Middleton family is the most welcomed. They are allowed to stay at Balmoral and welcomed at Prince Charles' Scottish retreat Birkhall. They also rode the royal carriages at Ascot races, invited for lunch at Windsor, and attended the Royal Box at Wimbledon and other high-profile events.

Seward added that the Queen was even delighted that Prince William married Kate Middleton because compared to Princess Diana and Sarah Ferguson, she came from a well-bonded family. Allegedly, Her Majesty believed that the problems created by the two former wives of her sons were due to their lack of stable family life.

They both came from a broken family, which was different from Kate Middleton's. Although she is only an ordinary girl, she has a solid background. She also has the indispensable family support that helps her get through the rough road of being the wife and mother of future monarchs and Duchess of Cambridge.
