Are you wanting a single syllable name for the middle name again?
I found it easier to work out what kind of flow we wanted the name/s to sound like and then focussed on shorter or longer names.

Dolcie Ayla
Dolcie Eve/Eva (hang on, Dollie Eva, sounds like Diva, maybe not that one)
Dolcie Elena
Dolcie Ilona, although Dollie Ilona sounds a bit weird
Dolcie Jae
Dolcie Kiera
Dolcie Maya or Dolcie May/Mae
Dolcie Neva
Dolcie Pearl (I had a great, great aunt with the name Pearl and she was gorgeous in her black and white photos)
Dolcie Rose
Dolcie Vella Rose
Dolcie Yasmine
Dolcie Zara (sounds better as Dollie Zara)
