SHER SIṄGH CHHĀCHHĪ (d. 1814), son of Ṭahal Siṅgh Chhāchhī of Kohlī Khatrī caste, served under Mahārājā Raṇjīt Siṅgh. As his ancestors had settled in Chhachh, in Attock district (now in Pakistan) the family came to be known as Chhāchhī. Sher Siṅgh succeeded to the estates of his father along with his two brothers, Jassā Siṅgh and Fateh Siṅgh. He took part in several of the Mahārājā's early campaigns of conquest receiving large additions to his estates at Bharatpur, Sāhīvāl and Kuñjāh. He served at Kask in Piṇḍ Dādan Khān district, at Piṇḍī Gheb and Jhaṅg and joined the expedition against Kashmīr in 1814 in which he was killed.
