I really like the name Eliana, but would prefer to avoid the over popularity of Ellie. What are the chances she could just be an Eliana? We actually don't have any Ellie's in any of our current kid circles, but there are 3 Ellas between daycare and soccer. They all go by Ella, not Ellie.
Re: Eliana = Ellie?
That said Ana could possibly be a good nickname option if you want to discourage the obvious Ellie.
