By the 19th century, the K'ómoks had been driven out of their lands by a particularly fierce group of Kwakwaka'wakw, the Lekwiltok, who raided other villages to capture slaves. The K'ómoks migrated south to present-day Comox, where they allied with the resident Pentlatch against their common enemy. In 1862, a smallpox epidemic swept across Vancouver Island, killing an estimated 30% of First Nations people. A census of First Nations in the Comox Valley taken in 1876 revealed that the local First Nations population had dwindled to only 88 K'ómoks and 21 Pentlatch.
