Gwenyth is a variant of Gwyneth, a Welsh name of uncertain origin that is usually explained from the region of Gwynedd or from the word gwynaeth, "happiness" or "blessedness", with the element gwyn, "white", in the background. The actress Gwyneth Paltrow keeps the sound familiar. Gwenyth stood at number 2489 in 2000, peaked at number 1332 in 2013 and has slipped to number 2970 in 2025.
