Great discussion about names! :) I find the exoticness (I know that's not a word
) of names so much depends on the culture you're in. In Norway, there was a period in time where Tom, Linda, Martin etc became very fashionable as they were 'exotic' and 'British-sounding'. In 2010, in the top 30 girl baby names in Ireland were: Aoife (10), Saoirse (I don't even know how to pronounce that), Caoimhe, Niamh, & Ciara. I don't think these are even used at all in England other than by Irish families.
In the top ten of most popular boy names last year here in Norway were: Lukas, Emil, Mathias, Magnus, Jonas, Kristian and for girls: Linnea, Nora, Ingrid, Thea, Ida and Maja. Most of these would be fairly uncommon in the UK. Emma, Sara, William, Oliver & Alexander are gaining massive ground here at the moment, but are all quite 'exotic' (with the exception of Sara) & non-indigenous.
Angelico - I do agree with you up to a point. Some of the kids I remember in primary school with 'unusual' names, either used their middle names or insisted on nicknames. One girl named 'Fanny' was bullied SO much she insisted on being called 'Rebecca' and changed it by deed poll as soon as she was old enough (I think, in the end, with her parents permission, pre-18). Some loved them though. One 'Oriel' seemed to not get teased and Rudolph (Rudy) was much saved by The Specials release of the single in 1979, propelling him to cooldom :)
I have to be careful what I choose as some British names sound awful pronounced in Norwegian. Had been keen on 'Bill' as it was my late father's nickname but here 'bil' (pronounced nearly the same) is the word for car and come on, none of us would call a child 'car' would we?
Don't know if I could get away with 'Billy' but that's often a girl's name now isn't it?
