Phryne is probably up there with Triphena and Tryphosa. My DH thinks that Daphne is dead and buried. These are heading into the old fashioned Greek-sounding names. There are probably a lot from that pool you could use.
I am another who finds it hard to believe that names like Wayne, Darren and the like will come back. I've got a friend who once considered Crispin and Taliesin as names. I can't see them making a comeback though! But, pop culture will play a huge part. Who would ever have predicted Hermione would make a comeback prior to Harry Potter?
