Etymology
Lewallen is generally understood as a surname derived from the medieval personal name Lewis, ultimately from the Germanic name Chlodovech, the source of modern Louis and Lewis. The final element -allen is less certain: it may reflect a regional or dialectal surname ending, or a later spelling reshaping of an earlier form. In short, the name probably began as a family-name derivative of Lewis rather than as a place name or occupation.
History
Lewallen is most familiar as an English-language surname found in North America, where spelling variation was common and many names were reshaped over time. Because the form is relatively uncommon, its exact pathway is hard to document confidently, and it may represent more than one family line with similar-sounding origins. Modern bearers are especially concentrated in the United States.
