While still a teenager, and well before he had even given thought to a career in films, the young Kumudlal was married to Shobha in a match arranged by their parents in the usual Indian style. Their lifelong marriage was a harmonious and conventional one, and despite his film career, the couple retained a very middle-class outlook and value system, bringing up their children with traditional values in a remarkably simple home. They were the parents of one son, Aroop Ganguly, and three daughters named Bharati Patel, Rupa Verma and Preeti Ganguly. Their son, Aroop Kumar Ganguly, worked in exactly one film, appearing as hero in Bezubaan (1962), which flopped at the box office. He then made a career in the corporate world. Ashok's eldest daughter, Bharati Patel, is the mother of the Actress Anuradha Patel, who is married to actor Kanwaljeet Singh. Ashok's second daughter, Rupa Verma, is the wife of the actor and Comedian Deven Verma. Ashok's youngest daughter, Preeti Ganguly, was the only one among his daughters to enter the film industry. She acted as a comedienne in several Hindi films during the 1970s and 1980s, and died unmarried in 2012.
