The Gods: #75692 Is Gremory the legendary queen Gudrun?

Lately I can't stop thinking about whether the Demoness Gremory is the legendary queen Gudrun.

Especially knowing that many legends from medieval times have a much older origin, such as the fact that the Irish mythological hero Oscar is the Demon Forcas.
Or that the Hungarian mythological hero Csaba is actually the Babylonian God Dumuzid.
