Analysis of information sources in references of the Wikipedia article "Charan Singh" in English language version.
Charan Singh was born on 23 December 1902 in village Nurpur, Meerut district, United Provinces, the eldest of five children of Meer Singh, a small farmer, of the Tewatiya gotra of the Jat caste, and his wife, Netra Kaur, from a village in Bulandshahr district. The Tewatiya clan originally comprised five villages in Gurgaon district of present-day Haryana, but, ultimately, during the Mughal period expanded as revenue collectors for some 210 villages. One of the clan members rose to some prominence toward the end of Mughal rule, but brought the clan to destruction by supporting Bahadur Shah Zafar against the British in 1857 and was himself hanged. Thereafter, the clan remnants moved across the Yamuna, and established a presence in Bulandshahr district of western UP.
