During the reigns of Maharaja Kharak Singh and Maharaja Sher Singh, Kahn Singh and his three sons Fateh Singh Jodha Singh, Lahina Singh were treated with favour and received military appointments but when Raja Hira Singh rose to power, trouble came upon the family and not until Jawahar Singh became minister did it regain its former position. Kahn Singh was killed by a musketshot in 1846 during the first AngloSikh war.
