I like:
James
Ronan
&
Esmé
Evangeline
Iris
Juliet
Rosalie
Saoirse
Scheherazade "Zadie" (!!!)
Xenia
I also really like Seraphine and Sapphira, which are similar to your Seraphina and Sappho - though I understand, of course, are not the same. I'm just illustrating that we have very similar tastes in feminine names (especially Scheherazade "Zadie"!).
