You have really lovely taste! With the eception of
Amelia,
Violet,
Isabel, and
Bianca, all are names I'd consider.
Cora I have mixed feelings on. On one hand, it's very pretty - but I still picture an older woman with the name. I knew one, and she wasn't the type of older woman I admire.
Cora June is pretty, but I'd use
Cora Isabel.
