Elnathan

Its -Nathan part is too recognizable to be paired with 'El'. I perfectly know the meaning of El- but here it seems an article (like in 'El Alamein' or 'El Paso).

I like it, but wouldn't use it. He would get confused for Nathan possibly, which may get annoying. But I find this name much better than Jayden, Cayden, Brayden, and all those Ayden names, and would use it before one of them.

Quite the neat name. I wouldn't personally use Elnathan in most situations, but I admire it from afar -- especially if one were to place emphasis on the first syllable.

Maybe it's because I grew up around a lot of Spanish people, but this name looks like "the Nathan". I much prefer Nathanael.
