Jacqueline Kennedy Onassis, popularly known as Jackie, had a close-knit family that shaped her upbringing before she became the First Lady of the United States. Born on July 28, 1929, to stockbroker John Vernou Bouvier III and Janet Norton Lee, Jackie grew up in a vibrant household with her sisters and two stepsiblings as her family expanded over the years.

Jackie’s sister, Caroline Lee Radziwill, known as “Lee,” was born on March 3, 1933. Jackie remained the only child for nearly four years before Lee joined the family. The Bouvier family expanded again in 1942 when Janet, having divorced Bouvier III in 1940, married Hugh D. Auchincloss, a wealthy heir. This marriage brought three additional stepsiblings into Jackie’s life: Hugh D. Auchincloss Jr., Thomas Gore Auchincloss, and Nina Auchincloss Straight.

Nina, the youngest of the Auchincloss siblings, was particularly influenced by Jackie, describing her as a significant figure throughout her life. In a 1981 interview with The New York Times, Nina expressed her admiration for her big sister, stating, “I traipsed after her everywhere… She has great character, courage, and discipline.” Jackie and her family continued to grow, with the births of Janet Jennings Auchincloss in 1945 and James Lee Auchincloss in 1947.
Jackie’s bond with Hugh Jr. was strengthened in their youth, as they had spent many summers together prior to their parents’ marriage. Hugh Jr. recalled the adjustment that occurred once Jackie became part of the family, noting, “Jackie was the second oldest, so she got the second-best room, which is this room with its view of the Bay at sunset.” The siblings maintained their connection well into adulthood, with Hugh Jr.’s daughter, Maya, unveiling the essence of their relationship—one filled with mutual respect and affection.
Jackie and Lee shared not only a sisterly bond but also a passion for travel. The two embarked on their first overseas trip together in 1951, when Jackie led Lee through Europe after her graduation. This was a formative experience for Lee, who had the privilege of joining her sister on various memorable adventures, including a goodwill tour to India and Pakistan in 1962 where they indulged in local customs such as riding elephants.
During her wedding to John F. Kennedy on September 12, 1953, Jackie had both sisters by her side in significant roles—Lee as matron of honour and Nina as maid of honour. Nina reflected warmly on her role during this momentous occasion, stating, “I always viewed myself as Jackie’s ‘Sancho Panza’ or sidekick.” Their relationship thrived on joy and camaraderie, blending camaraderie with familial duty.
Jackie’s relationship with Janet also flourished, marked by shared values and experiences. Notably, in 1966, Janet married financier Lewis Polk Rutherford at the same church where Jackie wed JFK, further intertwining their familial ties. Jackie was not only supportive but also played an active role in her sister’s life, with her children attending Janet’s wedding as flower girls and pages.
Hugh Jr. and JFK also shared an amicable relationship, brought together through Jackie’s introductions. Despite their differing political affiliations—Jackie being married to a Democrat and Hugh Jr. a Republican—the two seemed to find common ground through shared interests, particularly during social gatherings arranged by Jackie.
The Kennedy family tree was rich and vibrant, with Jackie being not only a mother to Caroline and John F. Kennedy Jr. but also an aunt to her brothers’ and sisters’ children, boasting at least twelve nieces and nephews. Hugh Jr. had twins, Maya and Cecil; Lee had two children, Anthony and Anna Christina; Nina bore three sons; and Janet welcomed three children of her own. This extensive network of family allowed Jackie to play an active role in their lives, making joyful memories together.
In a poignant reflection of their bond, Jackie remained a steadfast presence for Janet during her final days. Even as Janet lived in Hong Kong and established her own life, Jackie frequently visited her sister. When Janet lost her battle with cancer at the young age of 39 in 1985, Jackie was by her side, demonstrating the unwavering affection they had for one another amidst life’s trials.
As the world remembers Jackie Kennedy Onassis, the legacy of her close relationships with her siblings stands as a testament to a family deeply grounded in love and support. This intimate and interconnected familial bond not only shaped Jackie as an individual but also affected her approach to motherhood, friendship, and her esteemed role as one of America’s most iconic First Ladies.
