Caitlin Elizabeth Jennings’ Birth and Early Life
Caitlin was born in November 2006, joining a family that already included her older brother, Dylan. Bob Harris announced her arrival in a post dated November 14, explaining that Ken and Mindy had welcomed their daughter the previous night. That account places her birth on November 13, 2006.

Caitlin Elizabeth Jennings’ Parents
Caitlin’s parents, Ken and Mindy Jennings, met while attending Brigham Young University and married in 2000. Mindy previously worked as a preschool teacher. Their marriage began several years before Ken’s success on Jeopardy! brought him national attention, placing the beginning of their family life before his television fame.
Ken won 74 consecutive Jeopardy! games in 2004, two years before Caitlin’s birth, and later became a host of the show. He also developed a writing career, with books including Brainiac and Maphead. His work in trivia, television, and geography provides context for the attention surrounding the Jennings family.
Caitlin Elizabeth Jennings’ Brother, Dylan Jennings
Dylan Jennings is Caitlin’s older brother and the first child of Ken and Mindy Jennings. He was born in 2002, approximately four years before Caitlin. His birth came before Ken’s original Jeopardy! winning streak, while Caitlin arrived after that major change in their father’s career.
A 2026 PEOPLE interview offered a glimpse of Dylan’s activities with Ken. During the conversation, Ken described their plan to visit every Major League Baseball stadium. The story concerns time spent together by father and son; it does not describe Caitlin’s hobbies or suggest that she takes part in the same project.
Caitlin Elizabeth Jennings’ Education
Caitlin began college in September 2025, a milestone Ken shared in an Instagram post. He explained that his second child had left for college, making him and Mindy empty nesters. The announcement marked a change both in Caitlin’s education and in her parents’ daily life at home.
Good Housekeeping covered the family update that month, drawing attention to Ken’s reflections on his daughter leaving home. The account establishes when Caitlin started college but does not name her institution or subject of study. It therefore provides a starting point for her education timeline without describing a degree or career path.
Caitlin Elizabeth Jennings’ Life Away from Television
When Ken shared the news about Caitlin leaving for college, he included photographs of her childhood bedroom. The images showed murals he had painted years earlier. Alongside the education update, these pictures offered a personal detail about her childhood and the room she had left behind.
Ken has also described family life through humor. In his PEOPLE interview, he joked that his children sometimes accepted his advice because he hosted Jeopardy!, even when Mindy had already made the same point. His remarks offer a parent’s perspective on life at home, rather than Caitlin’s own account of her experiences.
