Gyneth is of Welsh origin and translates to 'fair stranger'. It's a unisex name, often used for both males and females. In the past, it was more commonly used in Wales but has since gained global recognition.
"Gyneth was a popular name for newborns during the early to mid 20th century, peaking at 13 births in 1920 and consistently having five or more births each year from 1905 to 1944, totaling 96 babies named Gyneth over those years."
