These surprised me:
Deirdre
Katrina
Giles
Nigel
Rashid
Deirdre has given me the impression of "posh" usage in England, at least, but I suppose it has fallen out of fashion altogether. And while Katrina wouldn't have the taboo of a hurricane in the UK, I suppose Katherine and Catriona would be more common. (Though I'd expect Katarina & Katerina to go "extinct" first - unless they already have.)
Nigel surprises me the most of all of these. I consider it a quintessentially English name ("Making Plans for Nigel," etc.). Has it just become so dated that it's unusable?
