About 1908 Oscar Samuelson settled at Napaiskak for a few years and then moved across the river where he opened a store and remained as a trader until his death in 1953. After the Oscarville store opened, a few Eskimo families settled near it, forming a village (Oswalt, 1963, p. 10). The village population was 11 in 1939 and 27 in 1950.
