Exchange in Braxton County, West Virginia, zip code 26619, was originally named Millburn by the owner of the mill there. When the post office was established in 1906 the first postmaster, Mrs. Samantha Duffield, suggested the new name because the stores, mill and blacksmith shop changed owners so often.
