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