“Roche, Rosie Jeanne Burke, Died on Monday 14th July 2025. Darling daughter of Hugh and Pippa, incredible sister to Archie and Agatha, Granddaughter to Derek and Rae Long. Private family funeral,” an obituary published by the Yorkshire Post on Saturday, July 19, reads in part. The notice also added that, “A memorial service will be held at a later date.”

Roche’s death comes a year after the unexpected passing of another royal family member.

At the time, several outlets reported that Thomas was found dead on February 25.

“It is with the deepest sorrow that we announce the death of Thomas Kingston, our beloved husband, son and brother,” a statement released by the Kingston family days later, on February 27, read. “Tom was an exceptional man who lit up the lives of all who knew him. His death has come as a great shock to the whole family and we ask you to respect our privacy as we mourn his passing.”
