Prince William and Prince Harry’s cousin Rosie Roche is dead at the age of 20.

Roche — who is granddaughter of Princess Diana’s uncle, which makes her William and Harry’s second cousin — died at her family home on July 14, the Sun reported Monday.

A firearm was reportedly found close to her at the property in Norton, England.

The coroner told the outlet police have deemed the death as “non-suspicious” and there was no third-party involvement.

Roche’s mom and sister found her body after she had been packing to go on a trip with friends, according to the report.

A spokesperson told the outlet that Roche, who was studying english literature at Durham University, “will be sorely missed.”

Reps did not immediately return Page Six’s request for comment.

The Yorkshire Post published her obituary on July 19, noting that Roche will have a private family funeral and a memorial service will be held at a later date.

She was described as “darling daughter of Hugh and Pippa, incredible sister to Archie and Agatha [and] granddaughter to Derek and Rae Long.”

This isn’t the only tragedy the royal family has suffered in recent years.

Thomas Kingston, the ex-boyfriend of Kate Middleton’s younger sister, Pippa, died from a self-inflicted gunshot wound in February 2024.

He was 45 years old when he was found dead with a “catastrophic head injury” and a gun close to his body at his parents’ home in a Cotswolds village in England.

Buckingham Palace honored his life in a statement.

“The King and The Queen have been informed of Thomas’s death and join Prince and Princess Michael of Kent and all those who knew him in grieving a much-loved member of the family,” an official statement read.
