Born in 2005, Rosie was the granddaughter of Edmund Roche, 5th Baron Fermoy, who was Princess Diana’s maternal uncle. Her link to the royal family comes through Diana’s side, making her a second cousin to Prince William and Prince Harry.

Though it remains unclear whether Rosie had met the princes personally, the shared lineage has drawn renewed attention to Diana’s extended family.

Rosie’s passing comes just months after another tragedy touched the royal circle: the death of Thomas Kingston, husband of Lady Gabriella Windsor, in February. His passing, too, was confirmed to involve no foul play.

In the wake of the news, many have taken to social media to express condolences to Rosie’s family. “A heartbreaking loss of such a young life,” one commenter wrote. Another said, “This reminds us that grief and struggle know no title or status.”
