Jarrett was born in Shiraz, Iran, to American parents James E. Bowman and Barbara Taylor Bowman. One of her maternal great-grandfathers, Robert Robinson Taylor, was an architect who is sometimes cited as the first accredited African American architect.
Her father, a pathologist and geneticist, ran a hospital for children in Shiraz in 1956, as part of a program where American physicians and agricultural experts sought to help developing countries’ health and farming efforts. When she was 5, the family moved to London for one year, later moving to Chicago in 1963.[5] Her parents were both African-American; on the television series Finding Your Roots, genealogical research and DNA testing indicated that Jarrett also has French, Scottish, and Native American ancestry.[6] One of her great-grandfathers was Jewish.
