Meaning and Etymology
The surname Williams is a patronymic name that literally means “son of William.” It originates from the English personal name William combined with the genitive suffix -s, which indicates “belonging to” or “descendant of” (see Wikipedia).
In Wales the same spelling arose as an anglicisation of the Welsh patronymic ap Gwilym, the Welsh form of “son of William.” Thus the surname has both English and Welsh origins, a fact reflected in its widespread use in both cultures (Wikipedia).
Multiple Origins
English origin: derived from the personal name William + genitive –s.
Welsh origin: anglicised form of ap Gwilym, the Welsh patronymic for “son of William.”
