twin names

Hi everyone,

We’re looking for a name for our twins. We’ve got the first name: Avi. They’re both boys.

For the second name, we were thinking of Elias—it sounds nice together, but it also feels a bit heavy and religious. That’s not what we’re going for. We’re looking for a tough, slightly unusual name. It could even be Celtic, for example. Any tips?

Thanks in advance!
