^During the 18th century, the surname Shafer is also spelled Shever, Scheffer, Schaeffer, Schafer, Shaver, and other permutations in various original documents. Although, among his descendants and within the historical record, Shafer is the more common spelling. See Armstrong, William C. and Armstrong Michael. Pioneer Families of Northwestern New Jersey. (Baltimore, Maryland: Clearfield Publishing, 1996 edition), 217. Note that with a German name, the German pronunciation of v is equivalent to an English f, which allows the two letters to be interchangeable.
