It's a rapidly changing market, but these are today's favorites:
Lila (pronounced the straightforward way, not Laila)
Nicole (we like the nickname Nikki, and we know two great girls with this name)
Combinations of the above for first and middle name?
As was pointed out by my mother, Lila could be used as a nickname for Viola (and we think maybe for Olivia too), so get two for the price of one? Or not?
