Names that go with Theodore and Frederic?

[Fdtj]

That’s it really! I need a boy name to go with Theodore and Frederic (Theo and Freddie) but struggling.
Preferably 8 letters to match the other two but not essential.
I thought it would be easy but apparently not!

Zachary

Ferdinand
Malachi

Bruno

Leonard (only 7 letters though)

Theo, Freddie and Lenny sound good together without being too matchy.

Sebastian (Seb)
Xavier
Archibald (Archie)

I really like your boys names! I think it’s the number of syllables rather than letters that makes them sound nice together - ideas for nice 3 syllable boys names-

Benjamin
Nicholas
Jonathan
Dominic
Maximus
Zachary
Gabriel
Oliver
Samuel
Harrison

I particularly like Harrison as it has 8 letters and 3 syllables with a nice classic 2 syllable nn (Harry). Theo, Freddie and Harry 😊

Dominic(Dom)
Sebastian(Seb)
Solomon
Gabriel
Nathaniel
Gregory
Augustus

I know not all of these have 8 letters

If you already had a Fred and a Ted, how about an Ed (Edward)

Archibald
Nathaniel

Wilfred
Benjamin
Otto

Tristram (Triz?)
Maradoc
Edelbert

Fred, Ted and Ed win it for me!

Theodore, Frederic and…

I have a thing about the number of letters matching too! I love PP’s suggestion of Benedict (8 letters and the “d” sound runs through every name)
Also
Matthias (8 letters nn Matti)
Nicholas (8 letters nn Nico)
Alastair (8 letters find this very handsome, charming, timeless)
Raphael (7 letters but I love it and it’s nn potential)
Sebastian (9 letters but works well with your other names)
Jonathan (8 letters, deserves a comeback, would nn him Nat)
Nathaniel (9 letters, again I love Nat and Natty)

oh and Dashiell - 8 letters I wanted this badly - I love Dash.

Also came on to add Benedict 😀

Christian
Julian
Marcus
Victor

I think you need three syllable so another vote for

Barnaby
Benedict
Montague
Malachai
Mortimer
Benjamin
William
Dominic
Harrison
Jonathan
Lancelot
Nicholas
Oliver
Roderick
Xavier
