evidence: Sang (Jadhang) is a small hilly village in Uttarkashi District, Uttarakhand, India, and claimed by Zanda County, Ngari Prefecture, Tibet, China. A tributary of the Jadh Ganga, itself an important tributary of the Bhagirathi River, flows through this place. [...] Jadhang village itself and Jad people living in Jadhang and Nelang valley are named after a man "Jadha" who was resettled here by British adventurer Frederick Wilson. The settlement document of Garhwal Kingdom, which administered this area, from that era reads, "Wilson invited certain Jadha from the upper Pargana of Kunawar in Bashahr state (now in Himachal Pradesh) to settle at Nilang, re-establish the hamlet of Jadhang and administered the area on behalf of Maharaja Bhavani Shah [r. 1859-71 CE]."[3] [...] The India-held valley of the Jadh Ganga river is also claimed by China.[4]
