I love your list, [name]Lucy[/name]! As usual. 
[name]Nicholas[/name] - it’s a bit boring for me, but my sister’s always liked it. I do like it as a MN, and I’ve been considering [name]Henry[/name] [name]Oscar[/name] [name]Nicholas[/name]. I mainly like it for the nn [name]Cole[/name]. 
[name]Zachary[/name] - I like the full name, a lot, actually, but I’m not a fan of its nns at all.
Still, I think it’s a cool MN.
[name]Callum[/name] - like a lot! I think I’d be more likely to use [name]Calvin[/name], but I lovelovelove [name]Callum[/name], too.
[name]Benjamin[/name] - I like it, but I love [name]Bennett[/name].
[name]Jack[/name] -
[name]Love[/name], love, love. If my first son isn’t [name]Jack[/name], I’m about 99% sure my second son will be! It has so much meaning to me personally, but I think it’s just fabulous for anyone.
[name]Finley[/name] - love. I think it’s so cute for a boy and so handsome for a man. [name]Finn[/name] is such a sweet nn.
[name]Laurence[/name] - not a fan, but I like this better than the [name]Lawrence[/name] spelling! It just looks softer and more classic.
[name]William[/name] - would you have a junior? I love it, but I would probably only use it as a MN.
[name]Rory[/name] - love, but I prefer it as a NN to [name]Rowan[/name] or [name]Riordan[/name] or [name]Gregory[/name] or something.
[name]Elliot[/name] - love, but I slightly prefer [name]Everett[/name].
[name]Gabriel[/name] - love. I would love to meet a little [name]Gabriel[/name], and the nn [name]Gabe[/name] is so cute.
[name]Noah[/name] - a personal favorite. [name]Love[/name].
[name]Isaac[/name] - love. It’s a MN on my own list.
[name]Oliver[/name] - like a lot, but it does feel a bit boring to me and I don’t love the nn [name]Ollie[/name].
[name]Jack[/name] - [name]Jack[/name] again? I still love it. Teehee.
[name]Beau[/name] - didn’t used to like it, but I love it now. I prefer it as a nn for something like [name]Bowen[/name] or [name]Brody[/name]…
[name]Philip[/name] - a bit too classic for me, but it is handsome, and I think the nn [name]Pip[/name] is just too cute.
(Seriously, I don’t know why I bother even commenting on your list… It’s practically impossible to find anything wrong with it. You always love such classic, charming, rich, strong, lovely names… I guess it doesn’t hurt that I love so many of your favorites, too, haha…)
With [name]Elena[/name] and [name]Violet[/name], I think my favorites are [name]Jack[/name], [name]Callum[/name], [name]Rory[/name], [name]Noah[/name], and [name]Finley[/name], but you seriously can’t go wrong with any of them!
Good luck!
