The Sidhuan family are descended from Ghuman, hence share ancestry with the Uthian, Bhilowal and Sowrian/Awan families. Dyal Singh was the first of this branch of the Sidhu clan to became a Sikh, and was killed in a battle near Anandpur, in 1698. His son Bhagwan Singh supported himself as much by plunder as by agriculture, and his grandson Arbel Singh, having built a fort at Sidhu/Sidhuan, and having collected some 200 horsemen, contrived to make himself master of forty surrounding villages. He had connected himself with several of the powerful neighbouring chiefs, marrying one son to a daughter of Sardar Gujar Singh of Lahore, and another to a daughter of Sardar Sudh Singh of Doda ; so that he was not disturbed in his modest possessions. His son Budh Singh, who succeeded him, was less fortunate, for Sardar Amir Singh of Sowrian/Awan, his kinsman, having invaded the estate and carried off a large quantity of plunder, Budh Singh pursued him, and was killed in an ambush laid by the enemy. Shortly afterwards Ranjit Singh seized most of the Sidhu territory, leaving in the possession of Kahan Singh about fifteen villages subject to the service of 26 sawars. He also made Kahn Singh commandant in a cavalry regiment, and gave Fatah Singh a subordinate appointment, Fatah Singh was killed in the Kangra campaign, in 1809, and his jagir was given to his brother Kahn Singh, who, however, did not enjoy it long, as he feel, with Jamiyat Singh and other members of his family, in the unsuccessful Kashmir expedition of 1814.
Dewa Singh, who was an infant at the time of his father’s death, received a grant of four villages worth 3,000 Rs. for his maintenance, subject to the service of four sowars, and in 1838 was placed in Prince Kharrak Singh’s force. In 1848 he remained faithful to Government and did good service against the rebel Dhara Singh of Gogaira. His villages, Bhudan, Bhattanwala, Dhar and Dilloki, worth 2,500 Hs, wero released to him for life, on payment of two-fifths as nazarana, and on his death Bhudan and Bhatianwala will be maintained in perpetuity to his heirs, on payment of one-third nazarana.
Dewa Singh resided at Sidhuan or Sidhu in the Lahore district, the village founded by his ancestor Ghumman.
