English and German : from Middle English, Middle High German west ‘west’, hence a topographic name for someone who lived to the west of a settlement, or a regional name for someone who had migrated from further west.This name was brought to North America independently by many bearers in the 17th and 18th centuries. Thomas West, 12th Baron De La Warre, was captain general of Virginia in 1610–11. The state of DE is named for him. One of the earliest permanent settlers was Francis West (1606–92), who came to Duxbury, MA, from Salisbury, Wiltshire, England, in or before 1638.

English, northern Irish, and French : from Middle English, Old French beste ‘animal’, ‘beast’ (Latin bestia), applied either as a metonymic occupational name for someone who looked after beasts—a herdsman— or as a derogatory nickname for someone thought to resemble an animal, i.e. a violent, uncouth, or stupid man. It is unlikely that the name is derived from best, Old English betst, superlative of good. By far the most frequent spelling of the French surname is Beste, but it is likely that in North America this form has largely been assimilated to Best.German : from a short form of Sebastian.
