Ganguly family

In a Bollywood film industry dominated by powerhouse families the Ganguly brothers and their family connections serve as an important bridge between the clans.

The Ganguly family are a family of film personalities active in the Hindi film industry. The family comprises the descendants of three brothers - Ashok Kumar Ganguly, Anoop Kumar Ganguly and Kishore Kumar Ganguly - and their sister Sati Rani Mukherkjee.

Kishore Kumar was married to Ruma Guha Thakurta (1950–58), Madhubala (1960–69), Yogeeta Bali (1975–78) and Leena Chandavarkar (1980–87).

Ganguly brothers:

History of the Ganguly family begins with Kunjalal Ganguly, a pleader (advocate) by profession coming from a long line of lawyers, and his wife Gouri Rani Devi, granddaughter of Raja Shibchandra Banerjee and sister of classical singer Dhananjay Banerjee. The celebrated brothers and their sister, who gave birth to the Mukherjees of Bollywood, were born to these two. Supposedly, Kishore Kumar inherited his sense of comedy from Kunjalal. Also, the most popular film featuring all three Ganguly brothers – Chalti Ka Naam Gaadi – was, supposedly, inspired by Kunjalal's Chrysler that he bought in 1928, a year before the birth of his youngest son.

If Rattan Bai from their extended family network is ignored, Ashok Kumar was the first person in the family to go into the film industry. His daughter Preeti Ganguly, son-in-law Deven Verma (married to his elder daughter Rupa Ganguly) and granddaughter Anuradha Patel also became accomplished actors. Ashok Kumar's son Arun Ganguly never joined the film industry.

Kishore Kumar was married four times. His wives were Ruma, Madhubala, Yogeeta Bali and Leena Chandavarkar (current widow of Kishore Kumar).

Among Kishore's wives Ruma (now Ruma Guha Thakurta) was the daughter of Satyen Ghosh (better known as Montey Ghosh) and a niece to Smt. Bijoya Roy, the wife of the legendary film director Satyajit Ray (son of writer Sukumar Ray and grandson of writer and publisher Upendrakishore Raychowdhury). Her mother Sati Devi, a talented singer, was the elder sister of Bijoya, the legendary director's wife. Amit Kumar, her son with Kishore Kumar eventually became a celebrity in his own right. Amit later sang duets with Krishna Mukherjee, a niece to his paternal aunt Satirani.
