I was told once Hugh is the nearest equivalent to Uwe, but i can't tell if thats correct.

According to https://de.wikipedia.org/wiki/Uwe, the only certainly known "relative" of Uwe is Ove, which is used in Scandinavian countries. Other than that, the origin of the name is unclear, and there is a theory it might be related to Oswald.

Owen seems pretty close, especially considering the Nordic variant Ove.

I think that similarity is accidental though. Owen is a Welsh given name. Ove/Uwe is Germanic.

Doesn’t appear to be correct, assuming the information here is correct: https://en.wikipedia.org/wiki/Hugh

“Hugo” would appear to be the German equivalent.

In Spanish our Hughs are Hugos
