Clio (I have a history degree. I have also owned a Clio car.)
Hebe, Daphne, Iris.
I did like Ariadne until I did Latin A-level and a lengthy set text Catullus poem, and very particularly an exam essay comparing Ariadne on Naxos and Dido at Carthage, but I realise most people won't have those associations...
And I liked Persephone when I was about 8, but then I thought it was pronounced Percy-phone and I'd be aware how confusing it might be at school.
