Griffith surname meaning

Griffith is a Welsh surname from the personal name Gruffudd or Gruffydd, conventionally glossed “strong lord.” The name was carried by medieval Welsh bearers and later became hereditary in English records. Griffiths is the expanded patronymic-looking form, while Gruffydd preserves the Welsh spelling; Gryffyth is an older variant. The traditional translation describes the given name’s elements, not a claim about every bearer’s character or rank. This catalog classifies Griffith as a parent’s-name surname with high confidence because the Welsh personal-name origin is consistently documented.
