A Shocking Royal Family Revelation
In 1987, the British public learned a disturbing truth — Queen Elizabeth II’s cousins, Nerissa and Katherine Bowes-Lyon, had been wrongly declared dead decades earlier and had spent most of their lives hidden away in a mental hospital.
The Sun broke the story, revealing that the two women, born in 1919 and 1926, had severe developmental disabilities and were institutionalized from a young age. Their mother, Fenella Bowes-Lyon, reportedly chose to conceal them from public view. Despite being recorded in the 1963 edition of Burke’s Peerage as having died in 1940 and 1961, Nerissa had actually died in 1986, and Katherine was still alive at the time the news emerged.
The revelation sparked allegations of a royal cover-up, public outrage, and lasting fascination, inspiring a documentary and later a storyline in The Crown.

Early Lives and Institutionalization
Nerissa and Katherine were daughters of John Herbert Bowes-Lyon, the Queen Mother’s brother, making them first cousins of Queen Elizabeth II. Their severe disabilities left them non-verbal and with the mental capacity of young children.
Caregivers later described them as mischievous but affectionate, able to communicate through gestures and noises. At the time, upper-class families often concealed disabled relatives to avoid public scrutiny, and the Bowes-Lyons were no exception.
After their father’s death in 1930, the sisters were first placed in Arniston School, which catered to disabled children of aristocrats. In 1941, they were moved to the Royal Earlswood Mental Hospital in Surrey, alongside three similarly disabled cousins on the same day. From then on, they were largely out of public sight.

The 1987 Exposure
The truth came to light when a Sun photographer, posing as a relative, visited Katherine and discovered she was still alive. The tabloid’s headline, “Queen’s Cousin Locked in Madhouse,” ignited public outrage. The sisters had been institutionalized for decades, declared dead in error, and seemingly abandoned.
