Not exactly fad names, but my name is Harry and my wife's name is Alice. We're both ~40 but have names that were more common for people born several decades before us. It's kinda fun.
Side note: In Sweden, Harry has once again become a quite popular name for children. My two-year old is named Harry and out of 15 kids at Kindergarten, there are two Harry :)
Ya, with the prince and the teen pop sensation it's coming back for sure.
