Uncommon names for babies

[Celestialwish]

Hi everyone!
I'm expecting twins due in late September and DH and I are struggling to think of names. My DH and I already have a son (biologically his from a previous relationship, Mum is not in the picture) called Zachary, who is 5.

We're not interested in weird/alternative spellings, but we do want something that is uncommon or unheard of, that still goes well with Zach's name.

Any ideas?

Zachary/Zach is fairly commonplace now (though lovely) so I think most “unusual” names wouldn’t really pair that well if that’s what’s important to you. Maybe consider names outside the Top 100 but that are still very well known with a Biblical link (like Zachary)?
