The Hennessy twins were born in Edmonton, Alberta, of Irish, Italian, Swedish, French, and Ukrainian descent. The arts were a regular part of their childhood. When they were young, the twins would make their own plays for the neighborhood children, charging them 25 cents each to attend. They also sang and drew well, frequently together. Jacqueline later lived in France for a time, becoming fluent in French. She later received a doctorate in French Literature.
Hennessy currently hosts the current affairs program Medical Intelligence for Rogers Cable in Toronto, Ontario. She also serves as associate editor of Chatelaine magazine. Hennessy has won several awards for her work, including the Canadian Nurses Association Award of Merit (recognizing health care reporting) and the Canadian Journalism Federation Greg Clark Award.
Prior to becoming a journalist, Hennessy dabbled in acting alongside her sister. In 1988, the two appeared as twin call girls in the David Cronenberg film, Dead Ringers. They also co-starred in a film written and co-directed by Jill entitled The Acting Class.
One of Hennessy's most visible performances was uncredited. In 1995, Jill Hennessy, who played Claire Kincaid on the NBC crime drama Law & Order, made a couple of crossover appearances as Kincaid on another series, Homicide: Life on the Street. During the filming of one of these crossovers, the production schedules of both shows overlapped. As a result, Jacqueline was recruited to play Kincaid in some courtroom scenes filmed for the Law & Order episode "Corpus Delicti", which aired in January 1996.
