Altair- I really like this name, it reminds me of science and magic, for some reason
Aurelian- to me this feels like a nationality, like australian or a classification, like reptilian
Cato- this is a little harsh for me, but I like it
Casimir- this really seems to fit the vibe you're going for
Damien- eh, feels slightly evil, or bad to me
Emrys/Ambrose - love both, Ambrose seems to fit what you're going for more, but I also really like Emyrys
Evander- I really like this
Faramond- very beautiful, It feels wild, like a moor
Gabriel- only ok, It seems to common for you
Hadrian- this name seems slightly malicious, maybe because I remember seeing it as a top choice for an evil dictator name on the writers board
Hector- I really love this
Herne- I really think you should use this since it was on your first list, you seemed so in love with it
Hugo- One of my favorites, but it seems to be more popular in the UK
Idris- ok, feels feminine to me
Isidore- same as Idris, but I still kind of like it
Lucius/Lucien - Feels kind of evil
Oliver - like, but I think is too popular for you, how about olivier
Orlando- ok, but in the U.S. I think of the city
Rainier- beautiful imagery, and I love the connection to family
Remiel- I really like this and the nn Remy
Robin- this is on my list, I Love the robin hood imagery and the freeness associated with birds
Roland- I like this
Rufus- It's ok, but it was the name of a naked mole rat on a TV show I watched as a kid, that's what I always think of, as well as Rufus Wainwright
Silvan- pretty, but in the U.S. There is a well known learning center by that name
Theron- Love, It seems free, but could be anything and seems like it would age well
Tiberius- seems a little cold to me
Tristram- I quite like this
Weyland- This seems ok, but a little off to me, I'm sure it has great meaning
My top ten would be:
Thanks Blade and Lovelywren!
We've got a top seven....
...would like to narrow it down to a top five...
I do miss Emrys, but perhaps it's for the best. I see it as an unimpeachable top 4:
Two in competition for the last slot:
Tiberius & Faramond
And I would eliminate Lucius. Much like, say, Sylvester, it has suffered from being the go-to villain name for too long (perhaps its proximity to Lucifer?). It looks and might be mistaken for 'luscious.' Lucy is a popular girls name, far far more popular than Lucian etc for boys, and it might lead to teasing.
I would remove Lucius and Tiberius, I love your choices, but I do miss your old list
I like Evander and Tiberius :)
My favorites would have to be
Everard - This was the name of the mysterious hunk who lived down the street from me when I was in school ;)
My favorites of those are either Rainier or Ulysses!
EDIT: I just saw you chose your top names. I choose Rainier!
To bring it down to the top 5 I'd cut:
Faramond (sounds too much like pheromone, and I think the natural NN that it would be shortened to (Fara) is very feminine)
and.... hmm... well.... maybe...
Rainier (but for me I grew up near Mt. Rainier in NW USA so it sounds so much like a place name for me, but if I didn't have that personal association I think this would be a cool name and I probably would instead cut out..........
Tiberius (I love old Roman names (a lot), but I find that there are many better ones out there with better meanings. This one has no real meaning, and I'm not a fan of what a shortened/natural nickname for him would likely become at school and such-- Ty-- whether you wanted that NN or not, I think it'd be pretty unavoidable at school since Tiberius is so long and there are no other natural NNs that I can think that come from it)
I'm sad to see Emrys gone, but I'm very happy to see my other favorites still around!
These would be my top four choices. Sad that Alaric and Robin to never made it back onto your newer list, though both were great name/names.
I have a quirky, sassy, booksh, independent little 2 and a 1/2 year old that we named Oscar. He suits it perfectly. His baby brother, Henry, just turned 1!
Of your names, I adore Felix and Hugo. Best of luck!
