Worcester Surname Origin(Locality). A county and city of England, which Bailey derives from Saxon Were, a forest, and Cester, a camp or city. I prefer deriving it from Warcester, the city or castle of strife, from the Saxon Woer, war, strife, with which the ancient British name agrees, called Caerwrangon, the castle or fort of strife and contention. It was a boundary for many years between the Britons and Saxons. (See Chester.)
