Our DelMarVa-lous History
Delmarva is an acronym of the names of the states that occupy it: Delaware, Maryland, and Virginia (abbreviated VA). The earliest uses of the term appear to have been commercial – for example, the Delmarva Heat, Light, and Refrigerating Corp. of Chincoteague, Virginia, was in existence by 1913. But general use of the term did not occur until the 1920s.
