Please help with a boys name to go with Theo

[Missingcaffeine]

My list of names is quite long at the moment so I need to narrow it down! I'm also open to other names that are not on the list! Thanks :)

Hugh
Hector
George
Arlo
Elliot
Luka
Toby
Oscar
Charlie
Thomas
Otto
Milo
Otis
Rufus
Dylan
Reggie

I like Thomas, Arlo and Rufus from your list. I prefer Lucien over Luka. George and Elliot are imo too popular at the moment. I know two Dylans and they are both naughty boys so that puts me off that name.
I suggest Matthew, Ezekiel and Henry.

Maybe Victor, Alexander, David or Severin?
I really like Thomas, Charles, George and Milo. And Henry, I agree with Bunny.

Alex
Benjamin
Henry
Isaac
William

Love the name Theo.

I think Charlie, Henry or Hugo would be nice sibling names.

The only Theo I know has a brother called Nathan. Probably not helpful...

As previous OP said please no more Tobys! Also don't really like Toby and Theo together.
Rufus is a fab suggestion, or maybe Robin?

Theo and Robin-fab

I know lots of Theos
They are Theo and Tom
Theo and Peter
Theo and Ben
Theo and Felix

Good luck whatever you decide!

My son is called Tobias, his son is Theodore. My grandfather was Thomas Theodore Redvers. But beware of matching initials, it can get complicated when the boys grow up and start getting mail!

Oscar was my first thought before I read your OP. Love it, apparently it's very popular but I don't know any little ones. Also love Luca & Milo from your list.

Rufus or Oscar

Love Milo and Hugo (I have a Hugo) but two 'o' names are a bit rhyme-y perhaps? Luca (I prefer with a c) and Oscar are my two favourites from the list. I also like Jacob, Dexter, Sacha and Zach.

I like Toby. Milo and Hugo are a bit naff and over used.
Laurence?
Simon?
Guy?

Otis is awful. I love reggie and Thomas (Tommy?) . They go lovely with Theo
I love love love otto!

I have Henry and if our second was a boy we would choose Theo

We have a Joseph and Theo (Theodore), had dc3 been another boy we would probably have gone with Ezra.

I think Felix goes well, but as pp said I would avoid names ending in 'o'. Although I love Arlo!
