Sibling name for Tobias

[Sb39]

Currently 35/40 with baby boy number two and having so much trouble finding a first name!
His brother is Tobias (goes by Toby) and would like a name to flow nicely with this (no T names please!)
Husband is a teacher and of course this just makes things so much harder🙈
Surname is Barker for reference

Current faves (luckily my OH and I agree on all of them!):
Frederick
Hugo
Rupert
Edmund
Barnaby

Would love opinions on which to go for or any other name suggestions you feel are similar! Please help!

I like them all except Barnaby which I agree with PP is a bit much with Barker.

Hugh
Theo
Felix
Miles
Robin
Guy
George
Laurence/Laurie
Tristan

Tobias and...
Roderick
Nathaniel
Hugh (like PP I prefer this to Hugo)
Caspar
Magnus
Christopher
Reuben
Matthew
Alexander
Daniel
Ivo

Agree with PP who felt Rupert was 'too posh'.

Oliver

I wouldn’t have another name ending in y in Tobias gets called Toby.
I really like Hugo or Rupert but what about Edwin or Sebastian?
