Belonged to Chakk No. 38 Nizampur Deva Singhvala, in Sheikhupura district, which contributed the maximum number of volunteers (15) from any single village to the corps of martyrs led by Bhai Lachhman Singh Dharovali for the liberation of Gurdwara Janam Asthan.

Bhai Harnam Singh was born on 7 Magghar 1958 Bk/20 November 1901, the youngest son of Bhai Ishar Singh and Mai Bhago. Of medium height and stoutly build, he excelled in rural sports such as weightlifting and wrestling. He however gave up the latter sport after imbibing the Khalsa pahul to keep his vows inviolate. His presence at the reformists' divan held at Dharovali on 1-3 October 1920 proved a turning point in his life and he plunged himself into the Gurdwara Reform movement with all his energy. He participated in the liberation of Gurdwara Khara Sauda. As the call came from Nankana Sahib, young Harnam Singh did not tarry a single day and forthwith joined the jatha of Bhai Lachhman Singh of Dharovali. He consoled his distraught mother with the words that she had two other sons in the family. The jatha was massacred to a man by the killers on 20 February 1921.
