Rattan Singh

Rattan Singh Gadwai (1805–1845) was an official who served Maharaja Ranjit Singh of the Sikh Empire. There are claims that he was a son of Maharaja Ranjit Singh and Datar Kaur, however this claim is in-dispute, as Rattan Singh belonged to a different caste from Ranjit Singh and evidence suggests he served as an non-biologically-related official in his court, not as a son.
