The real wild Gothic origin story is that the island of Gotland got overpopulated and they decided by lottery which 1/3 of them should leave.
What seems more accurate is that there were people near the Vistula River around year 1 who had cultural, linguistic, trade and - yes - genetic connection to people on the other side of the Baltic sea, and in the age of migration those people got moving, got into Arian Christianity and called themselves Goths. They did comparatively well in a time when most of Europe didn't, so they have plenty of descendants, many of them carrying ancestry we can trace back to people who lived in Scandinavia before year 1.
E.g., the North Island of New Zealand is called "Te Ika A Māui" in Māori, that is "the fish of Māui", and if you look at it from above, it definitely resembles a stingray.
What blows my mind is how Māori knew that before cartography or aerial mapping or satellites.
I understand how they likely did, Polynesians didn't spread across the Pacific by being clueless about geography and coastlines.
But still, a pre-literate society that was able to say "huh, this island half the size of the UK looks like a giant stingray" is pretty bloody cool.
The summary from https://en.wikipedia.org/wiki/North_Island is:
> According to Māori mythology, the North and South Islands of New Zealand arose through the actions of the demigod Māui. Māui and his brothers were fishing from their canoe (the South Island) when he caught a great fish and pulled it right up from the sea. While he was not looking, his brothers fought over the fish and chopped it up. This great fish became the North Island, and thus a Māori name for the North Island is Te Ika-a-Māui ("The Fish of Māui").
Does your perception of the stingray match the head location in local use?
> Names of certain tribes like Muaūpoko (mua upoko "front of the head") and Muriwhenua (muri whenua, "backland")
Muaūpoko is in the south of Te Ika A Māui.
