The name is most likely a compound of the surname "Ewart" and the suffix -ton, meaning town. The town's economy prospered particularly from 1957 when ALCAN established a bauxite plant nearby. The plant was later transferred to WINDALCO and was closed in early 2009 due to a fall in demand for aluminium as a result of the global recession.
