Like their cousinsPrince WilliamandPrince Harry,Princess BeatriceandPrincess Eugenieexperienced the pain and childhood upheaval of their parents’ very public divorce.

But their family healed, and the young women and their parents — Prince Andrew and Sarah Ferguson — have developed a close family unit that has helpedQueen Elizabeth’s granddaughters thrive.

Although Fergie and Andrew divorced in 1996, she still has rooms at the family home, Royal Lodge, and she has regularly said she and Andrew are the “happiest divorced couple” in the world.

“Beatrice and Eugeniehave had a stability that William and Harry have found painfully lacking in their lives,” says Ingrid Seward in this week’s issue of PEOPLE. “Although their early childhood was not good, those girls have had a very secure upbringing.”

Unlike William and Harry, Beatrice, 30, and Eugenie, 29 — who joined the Queenat Royal Ascoton Tuesday — have made careers in the real world of business, while continuing to contribute to causes close to their heart and pitching in to support the Queen and their father’s royal duties.

“They are independent, working women but are also aware of their position and where they can help,” says a family friend.
