I personally love the nickname ‘[name]Ellie[/name]’, and really all of the names that it could be short for! Which is your favorite, and if you see any that aren’t on the list/that you know of, comment those too! 
[name]Elizabeth[/name]
[name]Eleanor[/name]
[name]Eliana[/name]
[name]Eloise[/name]
[name]Eliette[/name]
[name]Eliora[/name]
[name]Elspeth[/name]
[name]Ellery[/name]
I like [name]Elizabeth[/name] and [name]Eloise[/name]. Have you considered [name]Elodie[/name]?
We are considering [name]Noelle[/name] as a full name for [name]Ellie[/name]. [name]Elizabeth[/name] is gorgeous and perfect, but is my [name]SIL[/name]'s name nd my first daughter’s middle name.
I really like @westatd’s suggestion of [name]Noelle[/name]!
[name]Elspeth[/name] is my favorite on your list, and the Scottish form of [name]Elizabeth[/name]. I really like [name]Elowen[/name] too as a long form for [name]Ellie[/name]! [name]Eleanor[/name] is the classic one, and it’s such a pretty name. It flows really well. Those would be my top suggestions. [name]Noelle[/name] is really cool as well!
My favorites from your list are [name]Elizabeth[/name] and [name]Eloise[/name].
[name]Noelle[/name] nn [name]Ellie[/name] would be really cute for a winter baby. And from your list my favourite is [name]Eleanor[/name].
We have an [name]Eliza[/name] that is also an [name]Ellie[/name]
Could be [name]Elsa[/name].
Or anything that ends in elle - [name]Giselle[/name], [name]Arielle[/name], [name]Brielle[/name], [name]Marcelle[/name]
I know an [name]Elida[/name] (ell ee da) that goes by ellie as well as an isabelle…also isabella?
I just thought of [name]Anabelle[/name], [name]Maribel[/name], and [name]Elia[/name] ([name]Elle[/name] ee ah).
I really like [name]Elowen[/name], [name]Eliana[/name], and [name]Elia[/name].
