Shared upbringing and family context
RFK Jr. and JFK Jr. grew up in overlapping periods within a tight extended family that spent considerable time at compounds in Hyannis Port and Hickory Hill. Both were frequently present at major family events, holidays, and political milestones in the 1960s and early 1970s. RFK Jr., born six years before JFK Jr., was old enough to act as a big-cousin figure at times, and the two attended some overlapping schools, including the Buckley School in New York and later the Commonwealth School in Boston. Their proximity in age and shared daily life during formative years created a lasting personal connection, even as their public profiles diverged.
How they are related: family tree details
At the top of the cousin relationship are their grandparents, Robert F. Kennedy’s parents—Joseph P. Kennedy Sr. and Rose Kennedy—and John F. Kennedy’s parents—Joseph P. Kennedy Sr. and Rose Kennedy—making RFK Jr. and JFK Jr. first cousins. Their mothers, Ethel Skakel Kennedy and Jacqueline Kennedy Onassis, were not related by blood but were both prominent figures in their own right. This shared paternal lineage ties RFK Jr. and JFK Jr. firmly within the same generational cohort of the Kennedy family, with overlapping childhood memories and sustained familial obligations across decades.
Differences in their public lives and careers
While both men belonged to the same family, their career paths and public personas evolved differently. RFK Jr. carved out a niche as an environmental lawyer and activist, building Waterkeeper Alliance into a global network and weighing in broadly on public health and corporate accountability. JFK Jr. moved into law and publishing, notably founding George magazine and later working as an assistant district attorney in Manhattan, before his death in a plane crash in 1999. These distinct trajectories reflect different interests and skills within the same privileged familial context, yet both remain emblematic of the enduring public fascination with the Kennedys.
