History & Origin
Gwynneth is a variant of Gwyneth, a name that looks back to the historic Welsh kingdom of Gwynedd and to gwyn, 'white' or 'blessed'. The doubled n is a personal flourish; the roots and the soft two-beat sound are unchanged from the standard form.
It has never been common, reaching only about twenty girls a year at its high around 2001, and the plainer Gwyneth has always outpaced it. The name reads as thoughtful and a little literary.
