KISHAN KAUR or Kanval Kaur, the widow of Raja Dharam Singh, was the mother in law of Thakur Singh Sandhanvalia, prime minister in Maharaja Duleep Singh`s emigre government at Pondicherry. Her son Nahar Singh, alias Nihal Singh, Raja of Ballabgarh since 1829, was implicated in the 1857 uprising and hanged by the British. Several of the Rani`s relations were deported to Burma. Rani Kishan Kaur, who was allowed to retain her private property, espoused the cause of Duleep Singh and helped in the transmission of letters and messages from Thakur Singh to his contacts in the Punjab.
