Imo another popular, timeless classic to match Benjamin and Alexander would be lovely - and I feel like something a little longer looks/sounds best with his brothers too (so less so names like George or James even though they are timeless classics).

William or Edward would work really well. Perhaps Oliver or Frederick, although their popularity has fluctuated a bit more over time. I also like how you’d then have differing origins too - Hebrew (Benjamin), Greek (Alexander) and Germanic (William, Frederick) or Anglo-Saxon (Edward) or Latin (Oliver), despite them all being matching multi-syllable classics with nice diminutive options.

ETA: You totally can have William with Benjamin - they’d be known as Ben, Alex and Will most of the time surely? I don’t know any William’s under 50 who get Bill (at least in the UK).

And I totally forgot girls too - for me Eleanor in particular or perhaps Charlotte, Emily or Sophie would match the “popular classic” vibes of the brothers.

I was pregnant with twins in the days before a scan told the sex. Their names, if boys, were going to be Thomas Benjamin and Alexander James. We thought that was a nice combination.

Couldn’t use them as I had two girls! 😂

@mumof1littlebuni think it’s the Bill and Ben possibility - I think Benjamin and William are lovely together though

So weird that loads of people aren’t giving girl options???

Ben and Alex are probably the most neutral names ever so it would be strange to then divert from that.

I really like Zoe and your boys will likely end up as Ben and Alex / Zander anyway! So wouldn’t overthink the letters

I don't really like Zander and Zoe together.

Some people like that sort of sibling similarity but it always sounds a bit gimmicky to me - kind of like an online children's clothing brand that specialises in pyjamas and underwear.
