William

Etymology

This surname comes from the given name William, which entered English through Anglo-French from a Germanic personal name, Wilhelm. The name is traditionally explained as having the elements meaning “will” or “desire” plus “helmet” or “protection,” so the sense is often given as “resolute protector” or “willful guardian.” As a surname, William is simply a rare form based directly on the baptismal name rather than one of its more common derivatives.

History

Medieval and early modern English surnames more often formed patronymics such as Williams, Williamson, or Wilson than the bare given name William itself, so William as a hereditary surname is comparatively uncommon. Nineteenth-century surname writers also noted that the personal name generated an unusually large family of derivative surnames. The given name became especially widespread in England after the Norman Conquest, which helped spread surnames built from it.
