This is the family tree of our great martyr Shaheed Udham Singh Kamboj: Shaheed Udham Singh Kamboj was a son of Tehal Singh and born on 26th December, 1899 at Sunam, Sangrur District, Punjab. He belonged to Kamboj family of Jammu gotra (sub-caste) and by his historic martyrdom upheld the valiant Kshatriya tradition of the Kambojas, a tradition which they have always kept up since their glorious Vedic Aryan days. Udham Singh was known at various stages in his relatively short life by the following names: Sher Singh, Udham Singh, Udhan Singh, Ude Singh, Uday Singh, Frank Brazil and Ram Mohammed Singh Azaad. Tehal Singh's name before taking amrit paan was Chuhar Singh. Tehal Singh was at that time working as a watchman on a railway crossing in the neighbouring village of Upall. He died in 1907. As Udham Singh's parents died at very early age of seven, he became orphan and was got admitted along with his elder brother Sadhu Singh in Centre Khalsa Orphanage Pultighar, Amritsar on October 24, 1907 with the help of Bhai Kishan Singh Rogi.
