I am loving all of these suggestions! Thank you all SO much. This thread has helped me fall in love with [name_f]Chiara[/name_f] even more. I truly believe it is the name, as DH loves it, too. 
However, we are having a slight dilemma over the spelling, so I think I’ll start a new thread about it!
Thanks again!
[name_f]Seraphina[/name_f]
On the list [name_f]Chiara[/name_f] gets my vote. Perhaps [name_f]Chiara[/name_f] Homily
Other name suggestions:
[name_f]Zita[/name_f] [name_f]Iolani[/name_f]
Ausra [name_u]Seraph[/name_u]
[name_f]Neoma[/name_f] [name_u]Dagny[/name_u]
I’m sorry for the loss of the precious darling. [name_f]Elle[/name_f] [name_f]Sophia[/name_f] is a stunning name💖Seraphina is my favorite name, and it is very lovely! I love the uniqueness and its meaning to you. The middle names that I’ll suggest are
[name_f]Seraphina[/name_f] [name_f]Pearl[/name_f] or [name_f]Seraphina[/name_f] [name_f]Rose[/name_f] or [name_f]Seraphina[/name_f] [name_f]Jewel[/name_f]
I suggested these because she will be like a gemstone to you and your family after a loss.
I think all the names fit well, but I think [name_f]Chiara[/name_f] and [name_f]Zara[/name_f] are best.
