His younger brothers were Jujhar Singh, Zorawar Singh and Fateh Singh, but they had been born to Mata Jito ji. Baba Ajit Singh was killed in the Second Battle of Chamkaur along with his brother Jujhar Singh. His other two brothers, Zorawar Singh and Fateh Singh, nine and seven years old, respectively, were bricked alive at Fatehgarh Sahib on order of Wazir Khan, governor of Sirhind-Fategarh.

Ajit Singh led one of the sallies and laid down his life fighting in battle of Chamkaur. Gurdwara Katalgarh now marks the spot where he fell, followed by Jujhar Singh who led the next sally.
