Susannah is much more appealing to me, but the sound of
Shoshannah is whispering, both delicate and a little sensual. It's nice to hear, and I like it in theory, but it doesn't appeal to me visually and would be absolutely terrible should your daughter develop a speech impediment.
I like
Shoshannah Miriam and
Shoshannah Rosemary.
