Which boy name do you prefer?
I like [name]Carlisle[/name], [name]Arthur[/name] and [name]Theodore[/name].
[name]Carlisle[/name] [name]Arthur[/name] would be my pick, bu of the ones on your list, [name]Carlisle[/name] [name]Benjamin[/name] would be my pick. It’s the one with a first name I like.
Looking through your list, I adore [name]Boone[/name], [name]Grey[/name] and [name]Sylvester[/name], and I’m also quite fond of [name]Arlo[/name], [name]August[/name] and [name]Rory[/name].
[name]Boone[/name] [name]Carlisle[/name], [name]Boone[/name] [name]Sylvester[/name], [name]Boone[/name] [name]Arthur[/name], [name]Grey[/name] [name]Arthur[/name], [name]Grey[/name] [name]Carlisle[/name], [name]Sylvester[/name] [name]Grey[/name], [name]Sylvester[/name] [name]Boone[/name], [name]Sylvester[/name] [name]Carlisle[/name]… So many wonderful combos can be made! 
Honestly I can’t choose between [name]Rex[/name] [name]Arthur[/name] or [name]Clark[/name] [name]Theodore[/name] both are simply perfection, there isn’t anything wrong with [name]Carlisle[/name] [name]Benjamin[/name] but it’s just not my style at all
Of the three I’d pick [name]Carlisle[/name] [name]Benjamin[/name].
Though, I’d personally switch it around to [name]Benjamin[/name] [name]Carlisle[/name].
I like [name]Carlisle[/name] [name]Benjamin[/name], but would also switch it around to [name]Benjamin[/name] [name]Carlisle[/name].
[name]Rex[/name] [name]Arthur[/name] sounds great and I don’t even like the name [name]Rex[/name] that much! [name]Clark[/name] [name]Theodore[/name] is very cute.
I hate to do this to you, but I love them all! They are all good choices. If I had to chose one, it would be [name]Carlisle[/name] [name]Benjamin[/name].
I’m afraid to say but I prefer your middle names much more than the first name choices. If I had to choose, I would rate them in this order.
1 [name]Carlisle[/name] [name]Benjamin[/name]
2 [name]Clark[/name] [name]Theodore[/name]
3 [name]Rex[/name] [name]Arthur[/name]
All of this. Exactly how I feel!
It does not get any better than [name]Clark[/name] [name]Theodore[/name]! I love it!!
I love them all but my favorite has to be [name]Rex[/name] [name]Arthur[/name]! You couldn’t go wrong with any of them♡
I really love [name]Rex[/name] [name]Arthur[/name]!
I’d second [name]Carlisle[/name] [name]Arthur[/name] if it were an option.
From the three you listed my preference would be for [name]Clark[/name] [name]Theodore[/name].
Some other thoughts:
[name]Rex[/name] [name]Arthur[/name] is well too Arthurian and Camelot for me. Not sure I’d want my child to be literally be called [name]King[/name] [name]Arthur[/name].
[name]Carlisle[/name] [name]Benjamin[/name] are both great names and [name]Benjamin[/name] is on my list I’m just not fond of the combination I can’t really say why.
I love [name]Clark[/name] [name]Theodore[/name]!
[name]Rex[/name] [name]Arthur[/name] is also nice.
[name]Don[/name]'t care for [name]Carlisle[/name] [name]Benjamin[/name], but it’s not awful or anything.
I like [name]Clark[/name] [name]Theodore[/name]. [name]Rex[/name] [name]Arthur[/name] also works.
I think [name]Carlisle[/name] may run into a lot of spelling and pronunciation issues.
[name]Carlisle[/name] [name]Benjamin[/name] is my top pick!
[name]Carlisle[/name] is just so unexpected, I love it. Paired with [name]Benjamin[/name], however, it loses some steam. Are you set on that combination?
[name]Don[/name]'t go for [name]Rex[/name] [name]Arthur[/name]! : O [name]Rex[/name] means ‘king’ in Latin so you’d basically be naming him [name]King[/name] [name]Arthur[/name] "-_-
Out of all of your names I’d have gone for [name]Benjamin[/name] [name]Theodore[/name]. [name]Carlisle[/name] is a place and I’m not a fan of [name]Clark[/name].
[name]Carlisle[/name] [name]Benjamin[/name]! [name]Rex[/name] [name]Arthur[/name] is dashing too. I’m not a fan of [name]Clark[/name] or [name]Theodore[/name], though.
I vote for [name]Clark[/name] [name]Theodore[/name]. [name]Clark[/name] is one of my favorites!
