It read: "When Saoirse's eyes are smiling, sure, 'tis like the morn in Spring. In the lilt of Irish laughter, you can hear the angels sing. When Irish hearts are happy, All the world seems bright and gay. And when Saoirse's eyes are smiling, sure, they steal your heart away."

Who is Saoirse Kennedy Hill?

Kennedy Hill was the only child of Courtney Kennedy, daughter to the late Robert F. Kennedy, and Paul Hill, a member of the 'Guildford Four' who were wrongly imprisoned for their suspected involvement with an IRA bombing in 1974.

The 22-year-old, who had spent a lot of time in Ireland as a child, was set to begin her senior year at Boston College in the coming weeks where she was a Communications major and Vice President of the College Democrats. 

The Irish American had previously spoken about her struggles with depression and mental health, writing in a 2016 piece for her high school newspaper: “My depression took root in the beginning of my middle school years and will be with me for the rest of my life. Although I was mostly a happy child, I suffered bouts of deep sadness that felt like a heavy boulder on my chest."

In a statement, the Kennedy family said: "Our hearts are shattered by the loss of our beloved Saoirse."

“She lit up our lives with her love, her peals of laughter and her generous spirit,” the family said. “[She] was passionately moved by the causes of human rights and women’s empowerment and found great joy in volunteer work, working alongside indigenous communities to build schools in Mexico. We will love her and miss her forever.”
