If I like...

[2ndBelgiumbun]

Ethan
Arthur
Nathan

What else might I like?

I try the 'shout them across the playground test' ...
Nathan doesn't come out nice that way.

Don't bother looking for more, choose from the other two

Nathaniel
Stefan
Tristan
Euan

Finley
Ewan
Wyatt
Nate (Nathan)
Jesse
Max
Isaac

Seth
Anthony
Dathan
Griffith
Jotham
Matthew

I fancied Nathaniel or Silas for DS (didn't get my own way though).

Love Nathan! My fav boys name!

Also like Leon, Joseph, Dominic, Aidan, Zac, Marcus, Dylan and Christian.

I know of an Ethan with brothers Benjamin and Finlay.

I know of an Arthur with brothers George and Frank.

Thanks all, some I hadn't considered at all here
