[name]Didier[/name]: I like the sound, meaning and feel of [name]Didier[/name]. I think it’s relatively straightforward to pronounce and spell.
[name]Evron[/name]: like the others, I think this is sufficiently unfamiliar as to not appear name-y to the average bloke, and people might free-associate to an exxon/chevron feel. Much prefer either the original [name]Ephraim[/name], or the Turkish name “Evren,” which means “cosmos.”
[name]Forest[/name]: this is perfectly fine, but it feels tamer and less interesting than the other names on your list.
[name]Heron[/name]: I think it’s distinctive, clearly nature-inspired, and very unique without being over-the-top. Paired with something dashing and classical (like-- randomly-- [name]Tiberius[/name] or Damocles-- it would be amazing. [name]Tiberius[/name] [name]Heron[/name]? [name]How[/name] cool would that kid be?!)
Hevel: I want to think of Vaclav Havel. I do. But I, too, see hovel.
[name]Indiana[/name]: I find this a very curious and incongruous choice for you. It’s a very uninspiring state in the US (it would be like naming your kid [name]Milford[/name] Keynes); it’s typically a female name, and-- how to phrase this politely-- it’s typically favored by ‘teen mom,’ somewhat chavvy elements. I think you can do far far better.
[name]Meredith[/name]-- I think in [name]Wales[/name] this is an old-man name (and not in the cool sense, more in the [name]Floyd[/name] & [name]Wilbur[/name] sense). So in most of the anglophone world it would be seen as a girls’ name, but in its place of origin, it’s leagues out of fashion. Perhaps instead Merlyon (“sea-lion,” an epithet of [name]Merlin[/name]), Merriman, Meriton, [name]Merrill[/name], [name]Merrick[/name]?
[name]Nero[/name]: I could never condone naming a child [name]Nero[/name]. It would be like calling him Stalin.
[name]Orfeo[/name]: I love the [name]Orpheus[/name] myth and even know an [name]Orpheus[/name] in real-life (he’s a very good radiologist who specializes in the liver). I understand how you might prefer the [name]Romance[/name] -o ending. But the ‘f’ kills it for me. You know how when people transliterate certain low-class British slang dialects, all the 'th’s become fs? Like “nuffink” for nothing? That’s how I read “[name]Orfeo[/name].” It takes all the elegance, charm, and mystery away. I’m not sure Orpheo would work, but I think it’s lots better.
[name]Quinn[/name]: blah. Not for everyone would I say this, but for you-- blah. It’s a unisex Irish filler name, the new “[name]Lynn[/name]” and “[name]Ann[/name].” If you’re considering [name]Heron[/name] and Chayyim, [name]Quinn[/name] has to go.
[name]River[/name]: I prefer nature names to be a bit more rarified, but it’s certainly nice. You could also think of the name of certain rivers (i.e. Orinoco, Rubicon, Yukon, Iriri). This to me would be a great way to conjure your desired image of “blue and green things” without beating people over the head with it.
[name]Robin[/name]: so sweet. At once medieval and modern.
[name]Ulric[/name]: this is a strong and distinctive name. I quite like it-- especially as a nod to your Nordic heritage. Since you like -ic names, you might also like [name]Alaric[/name] (a king of the Visigoths, meaning ‘leader’); [name]Aldric[/name] (“old, ancient power”); Amalric (another Visigoth king, meaning ‘the power of work’); [name]Edric[/name] (“rich, blessed ruler”); Godric ("God’s power, not just a Gryffindor); Mederic ("powerful ruler); and [name]Osric[/name] (“divine riches”).
[name]Wilder[/name]: this is both fun and problematic. The fun part comes from how evocative the name is; the problematic part is that it’s an everyday word, the meaning of which you might not necessarily want applied to your son as a 2-yr-old or a teen.
[name]Zooey[/name]: I get the literary roots, but think it’s a no-go.
From your also-rans, I like nearly all. I would simplify Chayim to 1 y; change [name]Lazarus[/name] to [name]Lazaro[/name] to avoid the leper association (though that’s pretty ancient so I’m not sure how problematic it would realistically be); and keep Elior, [name]Vassily[/name] (spelled thusly, the Greek way), [name]Wolf[/name] (?Wolfram?)and [name]Jasper[/name].
