Historians differ over whether Sher Singh and Tara Singh were Ranjit Singh's biologicala sons.
During March 1837, on the occasion of the marriage of Kanvar Nau Nihal Singh, Henry Edward Fane, the nephew and aide-de-camp to the Commander-in-Chief, India, General Sir Henry Fane, who spent several days in Ranjit Singh's company, reported that the Maharaja never thoroughly acknowledged Sher Singh.
The contemporary historian, Joseph Davey Cunningham, who attended the 1838 conversations between Ranjita Singh and Lord Aukland, also recorded that the Maharaja had doubts.

However, Khushwant Singh, writing in 1962, considered that the rumours regarding the parentage of Sher Singh and Tara Singh were inaccurate and had been spread by Kharak Singh and his mother, Datar Kaur, in order to reduce the possibility of Ranjit Singh preferring Sher Singh, who was fast becoming his father's favourite.
Despite his doubts, Ranjit Singh gave Sher Singh commands in the army and conferred honours on him, although Kharak Singh remained his favourite.
 However, no honours were bestowed on Tara Singh and he was not permitted to appear in court.
