Need Help Deciding on Spelling of Name

We want our son to be named (EE-luhn), but we would like to know which way to spell it and if we should use an accent mark over the E? Which is preferred from the following:

[name]Elan[/name]

Élan

Eelan

Éelan

Thanks for your help!

Another vote for [name]Elan[/name].

I say [name]Elan[/name]! easy, simple, neat!
