It is pronounced Fee-dra not fay-dra. And Ariadne is ar-ee-ad-nee not nay at the end.
Phaedra is a really beautiful name on its own but the mythology and play behind it - it is a very sad tale. I personally love and adore the name Oenone and would love to use it for a child, but again the story behind it is so unfortunate really.
You have some really lovely names on that list. Your list did make me laugh - it reminds me of my longlist when I was pregnant and obsessed with names, poor d wasn't named for days.
