“Our thoughts today are with The Duke of Kent and his family, particularly George, Helen and Nicholas,” they wrote. “The Duchess worked tirelessly to help others and supported many causes, including through her love of music. She will be a much missed member of the family.”

Their note was signed “W & C,” their first initials.

The Duchess of Kent, who was known for her kindness and humanity in the Royal Family, was 92 when she died. She became a Royal upon marrying Queen Elizabeth’s cousin Prince Edward, the Duke of Kent, in 1961. The couple welcomed three children together during their marriage: George, Earl of St. Andrews, Lady Helen Windsor and Lord Nicholas Windsor.

Katharine was also open about experiencing a miscarriage and giving birth to a stillborn son, becoming an advocate for those who had gone through the same thing.

Katharine took a more low-key approach to life as a royal and served as a music teacher in a school for over a decade in the 90s and 2000s instead of keeping up with public duties. In 2004, she founded the charity Future Talent, an organization that provides access to children who aren’t able to afford music lessons.

Her death was announced in a September 5 statement. “It is with deep sorrow that Buckingham Palace announces the death of Her Royal Highness The Duchess of Kent,” the statement read.

“Her Royal Highness passed away peacefully last night at Kensington Palace, surrounded by her family,” the statement continued. “The King and Queen and all Members of The Royal Family join The Duke of Kent, his children and grandchildren in mourning their loss and remembering fondly The Duchess’s life-long devotion to all the organizations with which she was associated, her passion for music and her empathy for young people.”
