Marjorie "Jackie" Harris (born 1956) is played by Laurie Metcalf on the series. Her mother revealed that her name was, or probably still is, Marjorie. But the 3-year-old Roseanne couldn't pronounce and instead called her "My Jackie". They all found it cute and began calling her that, until it became her name. She is the younger sister of Roseanne by 3 years, and the sister-in-law of Dan, and the loving and caring aunt of Becky, Darlene, D.J. and Jerry. Later in the series, she becomes the mother of Andy, and the wife of Fred (although they divorce after just over a year of marriage), and the great-aunt of Harris Conner Healy, the daughter of Darlene and her husband David Healy. The part of Jackie is appears in all but one episode of the series.
