He was the son of Shergill Jat Jagirdar Chaudhary Natlha Singh, who was the first in the family to have become a Sikh and who had joined the Kanhaiya misl under Jai Singh and ravaged the country around Ranghar Nangalia, near the town of Batala in Gurdaspur district. At Ranghar Nangalia, he built a strong fort. Karam Singh succeeded to his father`s estates, and increased both the power and possessions of the family. He rebuilt and strengthened the fort of Ranghar Nangalia, and took up his residence at Amritsar where he built a bazaar, Katra Karam Singh, also known as Katra Ranghar Nangalia Tari.
When Bhatti Jat ruler Maharaja Ranjit Singh seized Amritsar, Karam Singh swore fealty to him, and remained ever after his faithful servant. Karam Singh was captain of Ranjit Singh`s irregulars and he accompanied him on several of his expeditions. He possessed at one lime territory to the amount of several lakhs of rupees, principally situated in the Gurdaspur district. He was succeeded by his son, Jamial Singh, who had been for long in the army and was known for his bravery. Jamial Singh, with his cousin Ram Singh, was killed during battle in 1820.
