JAI SIṄGH (d. 1784), a Jaṭṭ Sikh of Mājhā living near the village of Aṭārī in Amritsar district, joined hands with the Nishānāvālī misl in its invasion of the cis-Sutlej tracts, fighting in the battle of Sirhind (1764) and assisting in the seizure of Ambālā, Shāhābād, Lidhrāṅ, Amloh and Sarāi Lashkar Khān. He obtained 34 villages as his share around Lidhrāṅ and Kharaṛ. Shortly afterwards Jai Siṅgh suffered defeat with his associates at the hands of Ahmad Shāh Durrānī and had to take refuge in the hilly country north of Ambālā. Rājā Amar Siṅgh of Paṭiālā annexed his seven villages around Kharaṛ. A serious discord erupted as Jai Siṅgh found himself strong enough to claim his possessions. Eventually a compromise was arrived at, Paṭiālā agreeing to surrender four of the villages. Jai Siṅgh's daughter was married to Rājā Jasvant Siṅgh of Nābhā.

         Jai Siṅgh died in 1784. His son, Chaṛhat Singh, who succeeded him, accepted British protection in 1809.
