Having a 3rd boy not sure what to name this one. My hubby is being VERY picky this time. Heres what i have… i like names that can be shortened.
[name_u]Douglas[/name_u]
[name_m]Leonard[/name_m]
[name_m]Vincent[/name_m]
[name_m]Joseph[/name_m]
[name_m]Rocco[/name_m]
[name_m]Sebastian[/name_m]
[name_m]Maximilian[/name_m]
What do you think? Any better ideas?
Congratulations! I love the style of your two boys. The name that jumped out at me was [name_m]Leonard[/name_m] as I love [name_m]Leo[/name_m]. (This might not work if [name_m]Theodore[/name_m] decides to go by [name_u]Theo[/name_u] one day!) I assume this baby will also go by his shortened name? I also liked [name_m]Sebastian[/name_m] as [name_m]Seb[/name_m] is really cute. I can absolutely see a baby [name_u]Max[/name_u] with [name_m]Archie[/name_m] & [name_u]Teddy[/name_u]. I prefer [name_m]Maximus[/name_m] as a longer form.
Certainly [name_m]Archibald[/name_m] comes across as a stately name to me, so I would look for a similar feeling. From your list I think that would be: [name_m]Vincent[/name_m], [name_m]Sebastian[/name_m], and [name_m]Joseph[/name_m].
I would suggest:
[name_m]Benjamin[/name_m]
[name_m]Balthazar[/name_m] ([name_m]Baz[/name_m])
[name_m]Benedict[/name_m]
[name_m]Bartholomew[/name_m] ([name_u]Ollie[/name_u] / [name_m]Bartley[/name_m])
[name_m]Cornelius[/name_m]
[name_u]Francis[/name_u]
[name_m]Frederick[/name_m]
[name_m]Franklin[/name_m]
[name_u]Lawrence[/name_u]
[name_m]Reginald[/name_m]
[name_m]Samuel[/name_m]
I like all of the names you listed. My favorites are [name_m]Vincent[/name_m], [name_m]Maximilian[/name_m] and [name_m]Joseph[/name_m]. The first name that came to mind before I opened the thread was [name_m]Harold[/name_m] with the nickname [name_m]Hal[/name_m].
I like [name_u]Douglas[/name_u] and [name_m]Maximilian[/name_m] the most.
What a classy set of names! I love [name_m]Sebastian[/name_m] and [name_u]Max[/name_u] from your list. Leondardo is wonderful too but agree you will end up with [name_m]Leo[/name_m] and [name_u]Theo[/name_u] which may or may not be an issue for you.
Some other suggestions for you:
[name_m]Alastair[/name_m] (love the nn [name_m]Ace[/name_m] for this one!)
[name_m]Edison[/name_m] (nn [name_u]Teddy[/name_u])
[name_u]Sullivan[/name_u] ([name_u]Sully[/name_u])
[name_m]Alexander[/name_m] ([name_u]Alex[/name_u])
[name_m]Samuel[/name_m] ([name_u]Sam[/name_u])
Wesley
Gideon
A preppy, shorter name would also work well with your other two. GPs I love that my husband will never agree to as firsts (haha): [name_m]Rhodes[/name_m], Yates, [name_u]Keats[/name_u].
Best of luck with your search 
I love your boys names! [name_m]Sebastian[/name_m] definitely gets my vote!

My favorites are [name_u]Douglas[/name_u], [name_m]Sebastian[/name_m], [name_m]Vincent[/name_m], and [name_m]Joseph[/name_m]. I prefer [name_m]Leopold[/name_m] to [name_m]Leonard[/name_m] and think it would work for your sibset. I love the suggestion of [name_m]Bartholomew[/name_m] above. My top choices for you are [name_m]Montgomery[/name_m] nn [name_m]Monty[/name_m], [name_u]Lawrence[/name_u] nn [name_m]Larry[/name_m], [name_m]Peregrine[/name_m] nn [name_u]Perry[/name_u], or [name_m]Gilbert[/name_m] nn [name_m]Gil[/name_m].

What fantastically named sons you have! I have three boys too, and a similar naming style (formal nicknames with informal nicknames). My sons are: [name_m]Sebastian[/name_m] (Bash), [name_m]Conrad[/name_m] ([name_m]Rad[/name_m]/[name_m]Raddie[/name_m]), and [name_m]Truett[/name_m] ([name_u]True[/name_u]). Other names we considered are:
[name_m]Winston[/name_m]
[name_m]Victor[/name_m] (ended up as [name_m]Rad[/name_m]'s middle name)
[name_u]Elliott[/name_u]
[name_m]Ebenezer[/name_m]
[name_m]Balthazar[/name_m]
[name_m]Augustine[/name_m]
[name_m]Calvin[/name_m]
[name_m]Eugene[/name_m]
I’m sure you’ll select something splendid!
My favorite of your list by far is [name_m]Sebastian/name_m, it’s a perfect fit! I also love the suggestions of [name_m]Benedict/name_m, [name_u]Sullivan/name_u, [name_m]Percival/name_m, and [name_m]Sylvester[/name_m]/[name_m]Silvester[/name_m]- the nickname [name_u]Sylver[/name_u]/[name_u]Silver[/name_u] would be interesting, and I think it sounds nice with [name_m]Archie[/name_m] and [name_u]Theo[/name_u].
I wasn’t sure if anyone suggested [name_u]August[/name_u] or [name_m]Augustus[/name_m] yet but that would go perfectly with [name_m]Archibald[/name_m] and [name_m]Theodore[/name_m]. The nickname [name_u]Gus[/name_u] fits well with the other two as well! Lots of great suggestions above
I love [name_m]Archibald[/name_m] and [name_m]Theodore[/name_m]!
I think [name_m]Sebastian[/name_m] ([name_m]Seb[/name_m]) and [name_m]Maximillian[/name_m] ([name_u]Max[/name_u]) are a great fit. I also like the suggestions of [name_m]Augustus[/name_m] ([name_u]Gus[/name_u]) and [name_m]Benedict[/name_m] (although I prefer [name_m]Ned[/name_m] as a nn, you may feel it is to close to [name_u]Teddy[/name_u]) and [name_m]Frederick[/name_m] (nn [name_u]Freddie[/name_u])
[name_m]How[/name_m] about (sorry for any repeats):
[name_m]Nathaniel[/name_m] nn [name_m]Nate[/name_m]
[name_m]Ezekiel[/name_m] nn [name_m]Zeke[/name_m]
[name_m]Finnian[/name_m] nn [name_u]Finn[/name_u]
[name_m]Gabriel[/name_m] nn [name_m]Gabe[/name_m]
[name_m]Zachariah[/name_m] nn [name_m]Zack[/name_m]
[name_m]William[/name_m] nn [name_u]Billy[/name_u]
[name_m]Albert[/name_m] nn [name_m]Albie[/name_m]
Matheus nn [name_u]Mattie[/name_u]
I second @lulu82 with [name_m]Nathaniel[/name_m] nn [name_m]Nate[/name_m]. Scrolling through the thread I was really surpised that it was only just now mentioned.
[name_m]Beauregard[/name_m]
[name_m]Abraham[/name_m] - [name_m]Ab[/name_m]
[name_m]Benjamin[/name_m] - [name_m]Ben[/name_m]
Great names! Of your list, [name_m]Sebastian[/name_m] goes the best with your son’s names but [name_u]August[/name_u]/[name_m]Augustus[/name_m] “[name_u]Gus[/name_u]” as brilliantly suggested by a prior poster would go even better in my book.
I have an [name_m]Arthur[/name_m], [name_m]Theodore[/name_m] “[name_u]Teddy[/name_u]” and [name_m]Felix[/name_m] and if our fourth is a boy, [name_u]August[/name_u] “[name_u]Gus[/name_u]” is a top choice. 
@dayhope [name_m]Arthur[/name_m] & [name_m]Theodore[/name_m] are two of my favourite boys names! ([name_m]Theodore[/name_m] is my absolute favourite!)
I think [name_m]Sebastian[/name_m] goes very well with your other boys names!
My favourite is definitely [name_m]Vincent[/name_m] “[name_m]Vince[/name_m]”.
