I got excited when I saw [name]Beau[/name] (it’s really growing on me) and then I almost fell off my seat when I saw you’re considering [name]Beauregard[/name], I think it’s absolutely awsome! I cannot put across how much charm, history and grace this name has, what more do you want! My other four - which really don’t compare to me - [name]Apollo[/name], [name]Leander[/name], [name]Lysander[/name] and [name]Finn[/name] 
Hmmm, what a cool list! I’ll see if I can narrow it down to just 5 :).
[name]Leander[/name] “[name]Lee[/name]” (prefer this to [name]Lysander[/name], but [name]Lysander[/name] is also handsome)
[name]Ambrose[/name] “[name]Bo[/name]” (cut [name]Beau[/name], because I think this stands out more. [name]Ambrose[/name] is wonderful!)
[name]Dashiell[/name] “[name]Dash[/name]” (favorite)
[name]Hawthorne[/name] (I’ve really come to love this name. It would be a bit of GP for me though)
[name]Bramwell[/name] “[name]Bram[/name]” (2nd favorite, love [name]Bram[/name])
Close seconds: [name]Roscoe[/name], [name]Aurelius[/name] “[name]Eli[/name]”, [name]Apollo[/name] “[name]Ollie[/name]”
[name]Finn[/name] (love it, but I feel like it’s too plain next to your other choices)
You know it’s a good list when you have to leave out [name]Hawthorne[/name], [name]Pascal[/name], [name]Dimitri[/name] & [name]Lysander[/name]! These are my very favourites:
[name]Ambrose[/name]
[name]Beauregard[/name]
[name]Raphael[/name]
[name]Lorenzo[/name]
[name]Aurelius[/name]
[name]Leander[/name] (would take the fifth spot if [name]Beauregard[/name] becomes [name]Beau[/name])
My five favourites are [name]Roscoe[/name], [name]Finn[/name], [name]Lysander[/name], [name]Ambrose[/name] and [name]Emilio[/name].
Such a fantastic list! This was really hard but my top 5 picks would be: (in no particular order)
[name]Finn[/name]
[name]Dashiell[/name] “[name]Dash[/name]”
[name]Bramwell[/name] “[name]Bram[/name]”
[name]Dimitri[/name]
[name]Hawthorne[/name]
Randoms middle name ideas:
[name]Finn[/name] [name]Alastair[/name]
[name]Bramwell[/name] “[name]Bram[/name]” [name]Evander[/name]
[name]Dashiell[/name] “[name]Dash[/name]” Rorrick
[name]Dimitri[/name] [name]Simon[/name]
[name]Hawthorne[/name] [name]Aurelius[/name]
[name]Beau[/name] [name]Lysander[/name]
[name]Lorenzo[/name] Aurelias
[name]Pascal[/name] Emilo
[name]Bramwell[/name] Aurelias
[name]Emilio[/name] [name]Finn[/name]
In order of like:
[name]Lorenzo[/name]! (in the process of adopting baby #2 - he’ll be [name]Lorenzo[/name] [name]James[/name] if he’s a boy!)
[name]Dashiell[/name]
[name]Emilio[/name] (family name but almost rhymes with our daughter’s name so we won’t use it)
Rapahel, like the nn [name]Rafe[/name] (rhymes with safe)
[name]Lysander[/name]
My favorite is [name]Leander[/name] and [name]Dimitri[/name], but here is my top five:
[name]Dimitri[/name]
[name]Apollo[/name] “[name]Ollie[/name]”
[name]Leander[/name] “[name]Lee[/name]”
[name]Hawthorne[/name]
[name]Bramwell[/name] “[name]Bram[/name]”
Top 5/6:
[name]Lysander[/name]
[name]Dashiell[/name]
[name]Bramwell[/name]
[name]Beau[/name]
[name]Aurelius[/name] or [name]Apollo[/name]
Wow guys! Thanks for all of the responses! I’m so grateful for all of the help! I will add up the scores and see which names were the most popular, and then I will start deleting names. 
I will have to do some arguing with [name]Theo[/name] over which ones stay.
I will keep the deleted names for possible middle names.
