Nicole Kidman was born in Honolulu, Hawaii while her Australian parents were temporarily in the United States on educational visas. Kidman can therefore claim citizenship in Australia and the United States. Her father, Antony David Kidman (1938-2014) was a biochemist, clinical psychologist, and author. Her mother, Janelle Ann (née Glenny), is a nursing instructor who edits her husband's books and was a member of the Women's Electoral Lobby. Kidman is of Scottish and Irish ancestry. At the time of Kidman's birth, her father was a graduate student at the University of Hawaii at Manoa. He soon became a visiting fellow at the National Institute of Mental Health of the United States. Opposed to the war in Vietnam, which was causing social unrest in both Australia and the United States, Kidman's parents participated in anti-war protests while they were living in Washington, D.C. The family returned to Australia when Kidman was four and her parents now live on Sydney's North Shore. Kidman has a younger sister, Antonia Kidman, a journalist and TV presenter.
