If our 3rd is a boy, we want a strong old fashioned name but we prefer 3 syllable names since our first 2 kids names have 4 and 2 syllables to tie them together. Is that dumb? Lol. Our kids are [name_f]Cordelia[/name_f] and [name_m]Ransom[/name_m]. The names we like are
[name_f][/name_f][name_m]Augustus[/name_m], [name_m]Everett[/name_m], [name_m]Finnian[/name_m], [name_m]Giorgio[/name_m], [name_m]Grover[/name_m], [name_m]Frederick[/name_m], [name_m]Lawrence[/name_m], [name_m]Lysander[/name_m], [name_m]Orville[/name_m], [name_m]Percival[/name_m], [name_m]Phineas[/name_m], [name_m]Reginald[/name_m], [name_m]Sylvester[/name_m].
[name_f][/name_f]They’re either just not clicking, too out there, or 2 syllables. Anyone have any suggestions? I feel lve read every list and census in the world 
The 3 syllable thing is not dumb at all. It does limit you, though. I suggested some 1 and 2 syllable names, too, just in case they click.

From your current list, I like [name_m]Augustus[/name_m], [name_m]Everett[/name_m], [name_m]Frederick[/name_m], [name_m]Lawrence[/name_m], [name_m]Lysander[/name_m], [name_m]Percival[/name_m], [name_m]Phineas[/name_m], [name_m]Reginald[/name_m], & [name_m]Sylvester[/name_m] with your kids’ names.
[name_f]Love[/name_f] your list so far! I would weed out the names that aren’t clicking first, then take another look at your out-there and 2 syllable names and consider if there are any you like / love well enough to use despite not ticking off every box.
[name_f][/name_f]Personally, I would take [name_m]Everett[/name_m] and and [name_m]Frederick[/name_m] off your list, since you’ve described your style as unique Victorian I don’t think these names are unique nowadays. Maybe even [name_m]Augustus[/name_m] since it may get shortened to [name_m]August[/name_m] which is super trendy rn (for great reason though!) and [name_m]Finnian[/name_m] may get shortened to [name_m]Finn[/name_m] as well.
[name_f][/name_f][name_f]My[/name_f] favorites with your other two are [name_m]Grover[/name_m], [name_m]Lawrence[/name_m], [name_m]Percival[/name_m] and [name_m]Phineas[/name_m]!
Like I said I would take another look at your more uncommon choices and see if there’s a name that you love regardless of its non popularity
[name_f][/name_f]good luck 
I really love [name_m]Phineas[/name_m] for y’all! He goes perfectly with [name_f]Cordelia[/name_f] & [name_m]Ransom[/name_m], and has that strong, old fashioned feel that you’re looking for. [name_m]Percival[/name_m] would be a close runner up!

I wouldn’t worry about the syllables honestly, I don’t think most people will notice and it really limits you for names that you like!
Of the names you like I like Finnian, Frederick, Lawrence (or Laurence), Percival, Everett, Augustus, Lysander, and Phineas best.

Out of curiosity, which are the two syllable names you’re really liking of these? Cordelia and Ransom are great, and so are a lot of these full names! I especially love Augustus, Everett, Frederick, Grover, and Phineas with your older two. What about:
Barnabas or Barnaby
Atticus
Leopold
Caspar
Julian
Cassian
Aurelian/Aurelius
Tobias
Orion
Abraham
Ambrose
Nathaniel
Simeon
Gideon
Rupert
Anselm
Amias
Raphael
Thaddeus
Benedict
Lucius
Leander
Percy (or Perseus, if not Percival?)
Augustine
Rolland
Edison
Gardner
Lucian
Marcellus
Dominic
Clement
Merritt
Gilbert
Lyndon
Bartholomew
Constantine
Loyal
Seymour
Elisha
Bertram (I know it’s only 2 syllables, but super cute with Cordelia and Ransom, and I love the idea of Bertie or Bram as a nn!)
Alphonso/Alphonse (nn Alfie?)
Ulysses
Harlan
Ferdinand
Emerson
Albert
Hiram
Rex
Ellis or Elias
Ernest/Earnest
Ira
Irving
Vincent
Sterling
Philip
Luther
Peter
Calvin
Arthur
Walter
Wallace
Super wanted to recommend Cornelius as I think he’d be PERFECT with Ransom, but obviously you can’t do Cordelia and Cornelius lol.
I don’t think it’s dumb to want a 3 syllable name to fit between Cordelia and Ransom, but the length from Ransom to Cordelia isn’t so large, and if you end up really loving a 2 syllable name, I would recommend going for it!
Good luck!
