The name Griffith has its origins in the Welsh language and culture. It is derived from the Welsh words "griff" meaning "vigor" or "strength" and "iaith" meaning "speech" or "language." The name can be interpreted as "strength of speech" or "vigorous language."

One of the earliest recorded instances of the name Griffith dates back to the 12th century. It was the name of Griffith ap Cynan, a Welsh prince and king of Gwynedd from 1081 to 1137. He was a prominent figure in the struggle against Norman rule in Wales and played a significant role in the preservation of Welsh culture and independence.

The name gained popularity in medieval England, particularly among the Welsh nobility. It was also adopted by some English families, likely due to its association with strength and power. Griffith ap Rees, a Welsh nobleman who lived in the 13th century, was known for his military exploits and leadership during the conflicts between the Welsh and the English.
