Need help with girl names!

Hannah
I am 21 weeks with Boy/Girl twins. The boy will be named Owen Bascom Craven. Bascom is my hubby's great grandfather's name. We are really struggling with a girl name though. Middle name will either be Hope (my maiden name) or Estelle (family name). Last name is Craven. Here are is my current short list...
Thea
Vivienne
Roselyn
Iris
Eleanor 
Elise 
Ada
Thoughts or ideas??
