Esme looks incomplete,
Esmee would be better and Esmée would be best. I think it goes with those names as sisters, not as mns. As sisters there are a lot of names that fit.
some:
Iris,
Vera,
Vianne,
Sera,
Aria,
Avalon,
Juliet,
Noelle
I used to know two sisters: Esmée and Meander (like a curve in a river)
