Hrm... the only ones that really work for me are
Goldie (which I guess could also be a nn for
Marigold),
Polly,
Billie and
Effie, the others feel a bit childish as full names.
I'd go for
Effie, but cheat and use
Fiammetta as a first name, I think it works.
"We have to live without sympathy, don't we? That's impossible of course. We act it to one another, all this hardness; but we aren't like that really, I mean...one can't be out in the cold all the time; one has to come in from the cold...d'you see what I mean?”
