Gwyneth was the original given name of the Broadway star and famous dancer Gwen Verdon (1925-2000), which may be why some people use Gwen as a pet form of Gwyneth even though the vowel sound is different.
Gwyneth Jones is a famous Welsh Wagnerian soprano, best known for the role of Brünnhilde in the legendary Centenary Ring production, directed by Patrice Chéreau and conducted by Pierre Boulez.
