It wouldn't be fit or proper to go through a list of all the famous women from the 1970s, and not visit the 'Brady Bunch' once. Maureen McCormick will always, in our hearts, be 'Marcia Brady.' Known best for her beaming smile, she captured the hearts of audiences, and was a major factor in the show's incredible popularity during its peak years.
McCormick was still young when the 70s began, but she was a veteran in terms of television. She'd had a short run on 'Bewitched' prior to her years as a Brady, but being Marcia made her one of the best-known faces in America. She was rarely off television screens for the rest of the decade, appearing in shows like 'The Love Boat,' 'Fantasy Island' and 'Happy Days.' She also broke out onto the big screen in 'Moonshine Country Express,' in a role very similar to her 'Brady Bunch' part.
