Bhai Gurbakhsh Singh was the son of Diwan Dharam Singh and grandson of Diwan Dargah Mall. In 1709, Mama Kirpal Singh Subhikhi (maternal uncle of Guru Gobind Singh Sahib) visited Amritsar from Delhi. Sirdar Gurbakhsh Singh too was with him. After deliberations Mama Kirpal Singh appointed a four-member Committee for the management of the town of Amritsar. Sirdar Gurbakhsh Singh was appointed as Daroga (superintendent) of Amritsar; hence his last name Daroga. His duty at Amritsar was to look after the treasury, the Langar, the cattle-shed etc. His son Kesar Singh Chhibber wrote a book Bansawalinama Dasan Patshahian Da.
