One of nine siblings, JFK wasn’t the only one in his family to enter politics.

Other siblings were also involved in public life, including Eunice Kennedy Shriver and Jean Kennedy Smith.

At the same time, theKennedy family is also famous for their personal tragedies.

But another tragic story is that of JFK’s eldest sister Rosemary Kennedy.

Here are the critical details of Rosemary’s life that have most recently come to light.

However, her birth may have robbed Rosemary of the necessary oxygen she needed.

It’s assumed that errors at birth caused her to have permanent behavioral struggles as well as developmental delays.

But why was Rosemary’s birth delayed, to begin with?

However, this didn’t occur for two hours.

The Kennedy family as kids

These included milestones such as crawling and walking, though her parents weren’t initially concerned.

She was also included in regular family activities.

However, as young Rosemary entered adolescence, she reportedly experienced frequent tantrums and outbursts.

These would also sometimes turn physical.

It also wasn’t easy being a Kennedy.

This inevitably caused conflict between the high-achieving Kennedy family and Rosemary, who was often misunderstood.

As Clifford Larson writes, she experienced “rising anxiety over standards she could never meet.”

This resulted in Rosemary shifting between several schools, further enhancing the teenager’s frustration and difficulties.

According to the National Park Service, Rosemary had to repeat grades due to a lack of academic development.

Moreover, Clifford Larson writes that she experienced extreme loneliness while attending boarding school.

Rosemary was temporarily enrolled at a Montessori school in England while her father was the Ambassador to Great Britain.

Rosemary preferred her social life, as was typical for people her age.

The controversial procedure involved severing lobes or lobe pathways in the brain.

This was accomplished by making small holes in the head.

Due to the emergence of medications, lobotomies are rarely performed in modern days.

Lobotomies were highly controversial procedures that sparked intense debates within the medical community and society as a whole.

This was tragically the case for young Rosemary Kennedy.

This forced her to reside in an institutional setting for the rest of her life.

She resided there for seven years, rarely receiving any visitors.

She was then transferred to Saint Coletta, a disability service and support organization in Wisconsin.

However, her mother would still make visits.

Clifford Larson writes that John F. Kennedy visited his sister Rosemary for the first time during his presidential campaign.

Rosemary received therapies and the attention she needed during her time at Saint Coletta.

As her siblings later learned what had become of their sister, they began actively visiting her.

Rosemary became especially close with her younger sister, Eunice Kennedy Shriver.

She was buried at the Holyhood Cemetery in Massachusetts where she is at rest with her parents.

Like their father Joseph P. Kennedy, Eunice suffered a stroke.

Patricia Kennedy died from pneumonia in 2006, and Senator Ted Kennedy died in 2009 from brain cancer.

Jean Kennedy Smith was the last surviving sibling of the Kennedy family.

She died in 2020 at the age of 92.

Such a tragedy should not be forgotten.

In 1968, Rosemary’s beloved sister Eunice Kennedy founded the Special Olympics, which now operates worldwide.

The Kennedy matriarch, Rose Kennedy, also reportedly made speeches to raise awareness about children with disabilities.
