It is true that many of the men in the Peshwa family had mistresses. Mastani was Bajirao's favourite but she could not be given the status of a lawfully wedded wife as she belonged to another community. Bajirao's family was endogamous, they were only allowed to take Brahmin wives and Mastani was not a Brahmin.
Bajirao maintained relations with wife Kashi and later Mastani and had children by both women. After 1737 he began spending more time with Mastani and also began eating meat and drinking alcohol. His licentious lifestyle and subsequent neglect of Kashi caused a scandal.
The first among the Peshwa family to remarry when the previous wife was living was Bajirao's son Balaji aka Nana when he took a second wife called Radha, 9 year old daughter of a rich moneylender. The idea was to access loans from her father for battle campaigns. However this marriage remained unconsummated as Nana died within months of the wedding.
Balaji Vishwanath had a mistress who bore him a son called Bhikaji. That woman also had another son but Balaji was not his father. Bhikaji used the surname Shinde because illegitimate children were not given the father's surname. They were referred to as Lekarwala in Marathi.This was also true for Mastani's son Shamsher who was brought up in his mother's Muslim faith. Shamsher died of battle wounds in Panipat.
Chimaji Appa did not have any mistress. His first wife Rakhma died in 1730 after giving birth to their son Sadashiv. Within a few months Radhabai got Chimaji married to another girl called Annapurnabai. She bore Chimaji a daughter called Bayabai in September 1740. Chimaji died in December 1740 and Annapurna went Sati by immolating herself in his pyre. Sadashiv was killed in 1761 during the battle of Panipat.
Nana, the firstborn of Kashi was married to Gopikabai who bore him three sons-Vishwas, Madhav and Narayan. Tragically Gopikabai was destined to witness the deaths of her husband and her three young sons during her lifetime. Elder son Vishwas died at Panipat. Madhav, who succeeded his father as Peshwa died of consumption at the age of 27 and his wife Rama went Sati with him.
Narayan was assassinated at the age of 19 soon after he succeeded his brother Madhav as Peshwa. His infant son Sawai Madhavrao was declared the Peshwa and Nana Fadnavis was appointed regent until the Peshwa reached maturity. Sawai Madhavrao died issueless at the age of 21.
Both sons of Bajirao- Nana and Raghunath had several mistresses who bore them many illegitimate children.
