I love your list! I have to say, I am a big fan of surnames, as well. 
[name]Booker[/name] - AHHHH! I have never seen anyone else considering [name]Booker[/name], I love your list just because [name]Booker[/name]'s on it! I think it’s just so cool, and since I’m an aspiring writer, I love [name]Booker[/name] even more because of that. I think it’s a great name, I absolutely adore it. I’m trying to decide whether or not it’ll make the cut for the last spot on my short list.
[name]Bowen[/name] - I love this, too! [name]Bowen[/name] [name]Charles[/name] was a combo on my long list a long time ago. I love the nn [name]Beau[/name]/[name]Bo[/name], and [name]Bowen[/name] just seems so handsome.
[name]Burke[/name] -
I like it because it reminds me of White Collar, haha. I have a minor obsession with TV shows, especially the ones on USA. haha. And [name]Peter[/name] [name]Burke[/name] is just too cool.
[name]Calder[/name] - It’s really grown on me! I love the nn option of [name]Cal[/name], and [name]Calder[/name] just sounds so natural and fun. It inevitably reminds me of [name]Eleanor[/name] [name]Calder[/name], but I don’t think that’s a bad thing, she seems like she’s a sweet girl.
[name]Cooper[/name] - I am not a fan, sorry. I never really loved the popular trade names that everyone seems to love ([name]Cooper[/name], [name]Parker[/name], [name]Carter[/name], [name]Tanner[/name], [name]Tucker[/name], etc.), but it is a nice name. [name]Just[/name] not for me.
[name]Dalton[/name] - I always thought this would be a cool name, since my great uncle’s last name is [name]Dalton[/name], I thought it might be a cool connection. After seeing it used, though, I have to say I don’t love it anywhere near as much as I thought I would! 
[name]Decker[/name] - It just reminds me of [name]Black[/name] and [name]Decker[/name]. And [name]Ted[/name] Dekker, the writer. I like [name]Declan[/name] a lot more!
[name]Easton[/name] - It’s grown on me a lot! I like it much more than [name]Weston[/name], which I see is also on your list.
[name]Finley[/name] - I like it a lot. I’ve considered it to honor my brother, since it means “fair-haired warrior”, and my brother is a fairhaired Airman, haha, but I would probably only use it as a MN. I much prefer [name]Finley[/name] on a boy than on a girl. 
[name]Finn[/name] - love [name]Finn[/name], but I much prefer [name]Flynn[/name], [name]Finnegan[/name], or [name]Phineas[/name], personally.
[name]Griffin[/name] - it seems to be very much on the upswing, but I have to say, I’m not really fond of it at all. I just don’t see the appeal. I went to school with a [name]Griffin[/name] in elementary school… he was a nice kid, but I’ve never loved his name.
[name]Gunner[/name] - too violent for me, I’m afraid. I used to sort of like it, though.
[name]Holden[/name] - I love this a lot, too. [name]Holden[/name] used to be on my top 5; I don’t love it quite so much anymore, but I still love seeing it used and considered.
[name]Hudson[/name] - [name]LOVE[/name]! I’m a huge fan of the -son names, and [name]Hudson[/name]'s probably my second favorite (only after [name]Grayson[/name]).
[name]Hunter[/name] - a bit too violent for me, I’m afraid.
[name]Lane[/name] - I used to know a family who had a son named [name]Lane[/name] [name]Everett[/name], I think that’s really cool. I can see [name]Lane[/name] more on a girl because of [name]Gilmore[/name] Girls, but [name]Lane[/name] is undeniably cool and classy on a boy.
[name]Noah[/name] - [name]LOVE[/name]! It’s a bit too popular for me these days, but I still adore it. I’ve been thinking of [name]Noah[/name] as a MN quite a bit lately.
[name]Nolan[/name] - I used to love it, but I really am not a fan anymore, I’m not sure why…
[name]Porter[/name] - I like it a lot.
[name]Ryder[/name] - A bit too [name]Flynn[/name] [name]Ryder[/name] to me, although I do like it (for some reason, though, I can absolutely get behind [name]Flynn[/name]!).
[name]Sebastian[/name] - like a lot, especially for the Shakespearean connection. I love the nns [name]Seb[/name] and [name]Ash[/name] for it.
[name]Sullivan[/name] - [name]LOVE[/name]! I think it’s just fabulous, nearly swoonworthy. I would love to meet a [name]Sullivan[/name].
[name]Walker[/name] - It’s funky and a bit old-soul… I like it a lot, but probably wouldn’t use it. It actually reminds me of Covert Affairs, the show on USA network. Probably because I was watching it just last night and I love that show. lol.
[name]Weston[/name] - I find it intriguing, but I do prefer just [name]West[/name] personally (or something like [name]Wellesley[/name]/[name]Wesley[/name]).
[name]Booker[/name], [name]Sullivan[/name], [name]Easton[/name], [name]Hudson[/name], [name]Holden[/name], [name]Noah[/name], and [name]Calder[/name] are my favorites.
Have you considered [name]Everett[/name], [name]Emerson[/name], [name]Grayson[/name], [name]Jameson[/name]/[name]Jamison[/name], [name]Beckett[/name], [name]Linus[/name], [name]Lucian[/name], [name]Brody[/name], [name]Spencer[/name], [name]Avery[/name], [name]Asher[/name], [name]Henry[/name], [name]Boone[/name], [name]Zane[/name], etc.? Those seem like they’d fit in very well with your other favorites.
Good luck!
