It’s no big secret that there was a falling out between Princess Diana and her immediate family following her separation from Prince Charles. Since her death, the Spencers have tried to make peace with the royal family by living her legacy through her children, Prince William and Prince Harry.

Following her passing, Charles Spencer, on behalf of the Spencer clan, promised to protect and guide Diana’s children as she would have. Fulfilling Diana’s wish, the Spencers’ presence is evident in the two young gentlemen’s lives.

Diana’s closeness to her mother, Frances Shand Kydd, and her sister, Jane Fellowes, inevitably made them present during the highlights of William’s and Harry’s lives. When William was born, the two women were among the first to visit Diana for the momentous occasion.

The Spencers were obviously smitten with the boy, going further to tell reporters of how much happiness they felt and how “beautiful” the baby was. Harry, on the other hand, was called “little Spencer” by his mother, who was struck by how reminiscent he was of Diana’s sister, Sarah McCorquodale.

Princes William and Harry would occasionally spend time with “Supergran,” a loving monicker they have for their beloved grandmother. They would also take trips with their aunts Jane and Sarah as they grew up, as seen in their 1990 trip to Necker Island.

The 9th Earl Spencer also recalls William’s enrollment at Eton College, of which he is an alumnus. He’d give the prince pointers on the basics of surviving the school — the pressure, cliques and terminologies — in the hopes that William would feel more comfortable in the new territory.

After Princess Diana’s tragic passing in 1997, Lady Sarah paid a visit to Prince William for his birthday. She would continue to visit the two boys in school, even after Prince Harry had enrolled in 1998.

The princes have remained close to the Spencers throughout the years after. This was more evident with “the little Spencer,” especially after his wedding to Meghan Markle, to which the entire Spencer family was invited.

When Harry’s baby, Archie, was delivered, the birth announcement from Buckingham Palace included the names of his aunts and uncle. More surprisingly, Jane was even among the first to have been introduced to Master Archie, even before William had seen the boy.

Despite the previous rift with their mother and her family, the princes keep the Spencers in their lives. As such, the promise of the Earl Spencer to Princess Diana lives on.
