HYANNIS PORT — Robert F. Kennedy's granddaughter Saoirse Kennedy Hill has died, the family announced Thursday night.

The Kennedy family's statement followed reports of a death at the storied Kennedy Compound in Hyannis Port, Massachusetts. The statement was issued by Brian Wright O'Connor, a spokesman for Saoirse Hill's uncle, former congressman Joseph P. Kennedy II.

Hill was the daughter of Robert and Ethel Kennedy's fifth child, Courtney, and Paul Michael Hill, who was one of four falsely convicted in the 1974 Irish Republican Army bombings of two pubs.

"She lit up our lives with her love, her peals of laughter and her generous spirit," the statement said, adding that she was passionate about human rights and women's empowerment and worked with indigenous communities to build schools in Mexico.

She attended Boston College, where she was a member of the class of 2020, the university confirmed to The Boston Globe.

The family statement did not include a cause of death.

The Cape & Islands district attorney's office said Barnstable police responded to a home "for a reported unattended death" Thursday afternoon, according to a statement cited by news outlets. Barnstable police and Massachusetts State Police detectives assigned to the district attorney's office are investigating.

"The world is a little less beautiful today," the statement quoted Hill's 91-year-old grandmother, Ethel Kennedy, as saying.

Robert F. Kennedy was gunned down in Los Angeles in 1968 after winning California's presidential primary. He had served as attorney general in the administration of his brother, President John F. Kennedy, who was assassinated in Dallas in 1963.
