A brother for Isabel - which one?

[doliketobebesidetheseaside]

Found out we’re having a little boy and struggling to pick a name!

We have a daughter named Isabel.

Would love to know which of the below people think works best as a sibling pair?

William
Theodore
Henry
Leo (DH likes Leonard but I’m not too sure)

We had also discussed: Sebastian, Nathan, Arthur, Albert, Ethan and Otto but only one of us is keen on each, so we seem to be narrowing on the above.

In general, we like fairly classic names, and bonus if it can work in other languages (German, Spanish). Surname is two syllables and starts with a “Z”.

Popularity isn’t too much of a concern for us (as you can tell given our daughter’s name).

Thanks in advance!

Leonardo

You can shorten it to Leo or lenny or Ardo

Leo

I like William and Henry.

Thanks so much all! Appreciate the suggestions, not too keen on Leon though. Love Leonardo but not sure if DH would!

Looks like the majority think Henry or William best with Isabel… interesting!

Joshua?

William is lovely. Suits a baby or a grown man and every stage in between. He could choose to be Will, or Billy.

I always think Henry is a posh sounding name and not necessarily in a good way.

Theodore, I think.

Leo or Nathan

I think William goes best out of your list. If you can’t use Oliver, what about Oscar?

Another vote for Henry

They are all nice names. Theodore is the least fvaourite for me.
Isabel and..
Henry
Nicholas
David
Leonard
William
Wilbur
Walter
Stuart

From your list I’d choose Henry.
Also like PP suggestion of Alexander.

I have Samuel and Isabel

Another vote for Henry here- Isobel and Henry are my kids names!

Vincent.

Jonah

William I find quite dull

Theodore is done to death and I think it’s in danger of feeling quite dated a few years from now.

Leo is nice and Leonard is great as a full name.

Henry is my favourite of your options, good strong name, goes great with Isabel

William is nicest.
Don't like Theodore.
Adam
Alexander
James
Edward
Zachary
Isaac

My son is Theodore and my daughter is Isabelle 😁 so that's my choice!

William and Henry from your list. Both classic and will never date.

Don't widen your options too much as it'll do your head in.

I think William goes best with Isabel, they have a similar flow which sounds nice

I think maybe Theodore.

I like William too but I think maybe it is a bit more traditional and ubiquitous than Isabel, which makes Theodore the better fit.

All work well. I'd go with Theodore

I love Theo!
I thought of Theo before I saw your shortlist.

I think Leonard is probably pretty marmite - and I think it's hideous. It sounds very dated to me. I like Leo though.
All the others are lovely and i don't think you can wrong with any of them.
