I've never really cared for Simone, though I find Simona endlessly charming. It's silvery and silken but a bit plaintive (perhaps because of the "moan"). What do you think?
Some combos:
Simona Irene
Simona Judith
Simona Helen
Simona Juliet
Simona Alice
Simona Agnes
Simona Amy (honoring)
Simona Clare
Simona Beatrice / Beatrix
Simona Ruth
Simona Hesper
Simona Iris (quickly becoming a go-to middle name for me...)
Simona Phryne
Simona Constance
Simona Eve
Simona Rachel
Simona Hester
Simona Sappho
Simona Verity
