[name]Felicity[/name] is stunning! My favourite nickname for it is [name]Lissie[/name].
Ottalie, [name]Olivia[/name] or [name]Veda[/name] are the 3 that match Esmee and [name]Siri[/name] to me.
Ottalie, Esmee, and [name]Siri[/name] sound very nice together as a sibset.
That’s my vote!
Esmee, [name]Siri[/name] and [name]Olivia[/name] (though, it seems that [name]Olivia[/name] is way more common than the others). Esmee and [name]Siri[/name] are short and spunky sounding, so I think I would stick with that theme. [name]How[/name] about [name]Willa[/name], [name]Ada[/name], [name]Ava[/name]?
I like [name]Olivia[/name] or [name]Geneva[/name] with Esmee and [name]Siri[/name].
Esmee, [name]Siri[/name] and sister…
1 [name]Veda[/name]
2 [name]Geneva[/name]
I would have included [name]Ottilie[/name] or [name]Ottoline[/name] if they were spelled this way. Esmee and [name]Siri[/name] are unusual so I think their sister should have a more uncommon name too.
Thank you all for your help so far. I totally agree with the poster who said [name]Olivia[/name] just seems to common to be entertained with sister’s named Esmee and [name]Siri[/name]… Truthfully I was thinking the same thing, but wanted to know if someone else would say it too. I also think I am going to take Gyweneth off the list; i am just not connecting - i love the meaning, but that is all right now. In regards to the spelling of Ottalie and [name]Ottaline[/name] - I just find using the A to be more feminine than the O. Thank you though for all your thoughts, they truly are appreciated. Nameing a baby is a very daunting task.
Therefore, I think i will update my new short list, but i am going to add [name]Hazel[/name]. I think it sounds kinda cute too, but no good nicknames cometo mind:(
The List:
[name]Ottaline[/name]
Ottalie
[name]Felicity[/name]
[name]Hazel[/name]
[name]Geneva[/name]
[name]Veda[/name]
Voting for [name]VEDA[/name]!
Esmee, [name]Siri[/name] and [name]Felicity[/name]. 
Esmee, [name]Siri[/name] and [name]Veda[/name]!!
