The Irish surname Erwin, also found in England and Scotland, is an anglicized form of the Gaelic name Ó hEireamhóin meaning “descendant of Eireamhón,” a personal name of uncertain origin. When found in Scotland the name is locational originating from the town of Irvine in Strathclyde or from a Celtic river name, with the component elements being "ir" or "yr" meaning fresh plus "afon", water. In England the name Erwin derives from the Middle English personal name Irwyn, Erwyn and Everwyn, from the old English pre 7th century personal name "Eoforwine". This is composed of the elements "eofor" meaning wild boar plus "wine", a friend. George Irwin settled in Virginia in 1640 and today there are approximately 22,000 bearers of the name Irwin in the US. .
