Boy name help

We're excitedly expecting a little boy early next year. We already have two daughters named Ari (like Carrie) and Isla. I keep being drawn to the name Elijah but I'm wondering if it's too close to Isla. Thoughts?

Other names on our 'maybe' list:

Benson Max Theo Seth Issac Ziggy Rhys Garrett Miles

Any other suggestions welcome please!
