[name]How[/name] can I get [name]Etta[/name] besides names that seems a bit abrupt like [name]Henrietta[/name] and [name]Harietta[/name]? They just feel very awkward to me.
Most names with ette or etta at the end would probably work.
Some ideas:
[name]Lisette[/name]
[name]Nicolette[/name]
[name]Margaret[/name]
[name]Elisabetta[/name]
[name]Cosette[/name]
[name]Claudette[/name]
[name]Marietta[/name]
My [name]MIL[/name]'s name is [name]Margretta[/name], that would work.
I’m currently loving [name]Estella[/name] as a full name for [name]Etta[/name].
Any name with an “et” can give the nn [name]Etta[/name]
[name]Loretta[/name]
[name]Antoinette[/name]
[name]Violet[/name]
[name]Colette[/name]
[name]Bridget[/name]
[name]Ethel[/name]
[name]Juliet[/name]
[name]Scarlet[/name]
Also
[name]Elizabeth[/name]
[name]Charlotte[/name]
[name]Esther[/name]
I know a [name]Marietta[/name].
Also stumbled upon the name [name]Minette[/name] not long ago.
I’m liking [name]Etta[/name] more and more as a name on it’s own, but my favorite long forms are [name]Violetta[/name] (vee-oh-let-ta) and [name]Marietta[/name].
Here’s everything I could find:
Etaina – she who shines
Etenia – the wealthy
Eteria – pure air
Ethana
Etinosa – strength of god

[name]Do[/name] you like any?
[name]Isabetta[/name]!! I think the other berries have covered them all!
The only one I didn’t see listed is Brietta
I’ll add [name]Greta[/name] =).
I love [name]Etta[/name], it was my great grandmothers name via [name]Henrietta[/name]!
[name]Violetta[/name] 
[name]Elisabetta[/name]
[name]Elizabeth[/name]
[name]Bethany[/name]
[name]Juliet[/name]
[name]Cosette[/name]
[name]Colette[/name]
[name]Nicolette[/name]
I like [name]Josetta[/name] best.
[name]How[/name] about [name]Bettina[/name]? Less obvious, but flows nicely. I also like [name]Marietta[/name] but I’m getting the feeling you’re looking for the less obvious options.
Perhaps [name]Etienne[/name]?
