Queen Elizabeth's Female Cousins Locked Away In Psycho Ward As They Were Considered An Embarrassment To The Crown — Inside The Scandal

The cold-hearted Royal family shamefully shunned five of Queen Elizabeth's female cousins — who were locked away in a mental institution — keeping their existence a secret for decades because they were considered an embarrassment to the Crown.

Sisters Katherine and Nerissa Bowes-Lyon and their cousins, the Fane siblings — Etheldreda, Idonea and Rosemary — all but vanished inside the grim, prison-like Royal Earlswood Hospital in 1941 when much of London was being destroyed by Nazi Germany's bombs.

At the time, Katherine was 15, Nerissa, 22, Etheldreda, 19, Idonea, 29, and Rosemary, 27.

The Royal cousins were considered severely mentally handicapped with the intelligence of 6-year-olds. Some were reportedly so mentally challenged that they were unable to speak.

While they lived like ignore paupers in a public institution, their Royal relatives whooped it up in mansions and palaces. The girls received occasional visits from some relatives early on — but they were completely shunned by senior Royals, said sources.

The Palace disgracefully kept their existence a secret for 46 years, only admitting the women were Royal relatives after their tragic story was made public.

The Queen Mother, their aunt and Queen Elizabeth's mom, claimed she didn't even know about them until 1982.

By then, her niece Rosemary had already passed away at age 58 in 1972.

"As soon as she found out, she sent money to buy them birthday and Christmas presents — but she hasn't actually visited," noted a source.

Ironically, one of the Queen Mother's pet causes was a Royal society that "campaigns against families dumping their mentally handicapped children into state institutions."

But the cousins were more than "dumped" — their disgraceful Royal relatives did their best to literally deny they were alive.

"Burke's Peerage," the bible of the nobility, declared that Nerissa had died in 1940 — a year before she actually vanished into the bowels of the dank mental hospital.

And her sister Katherine, the longest survivor of the group, was shamefully "listed as dead" in Burke's until 1961.

The false reports were blamed on the women's mother, Fenella Fane.

"The disturbing way both Nerissa and Katherine were listed as dead when they were still alive has been explained away by some as a 'slip of the pen,'" said a source.

"It is said that the girls' mother was 'extremely vague' when it came to filling in forms and might not have completed the paperwork correctly."

Nerissa was 67 when she finally passed on in 1986. She was buried in Redville Cemetery where "her grave marked with a plastic bag bearing just a serial number and her name," said a source.

Her cousin Etheldreda died in 1996. That same year, the hospital closed and the surviving cousins, Idonea Fane and Katherine Bowes-Lyon, were shipped off to Ketwin House, a home for the mentally disabled.

There, staffers nicknamed Idonea, "Baby," and Katherine, "Lady."

The shunned women became inseparable companions until early 2001 when Ketwin shut down.

Instead of keeping Baby and Lady together, the close cousins were heartlessly split up and shipped off to different facilities.

Four months later, lonely Idonea died at age 89. The official cause of her death was listed as "old age and severe learning difficulties."

But insiders believe she died of a broken heart. "She had lost the will to live after the separation" from her cousin Katherine, source said.

Like her two sisters, Idonea was buried in a pauper's cemetery.

Meanwhile, the fate of the lone survivor Katherine is barely known.

In 2002, a worker in a Surrey nursing home said: "Katherine is alive and well."

She reportedly "understands what she's being told and communicates by pointing, noises and smiles."

The last report of her was in 2007, saying she was alive in a nursing home.

She would have been 81 years old.

But the Royal family has apparently succeeded in obliterating Katherine's said existence and tragic fate.

In 2002, Harold Brooks-Baker of "Burke's Peerage" claimed he "could find no listing of her in any lineage records."

"She appears to have just vanished into obscurity," he said.
