Jelle

I adore the pronunciation of this name, as well as the way it looks and that it is a man's name.

If you're from an English speaking country or have any relatives who are, don't name your child this. It will get mistaken for 'jelly'!- haha
That child would have to change his name before deciding to travel abroad.

A popular name among Dutch parents who like this kind of short no-nonsense names (and that's the majority of them). Unfortunately, I don't think it ages very well, and it would sound quite strange on an old man.
