Canadian vs. American first names

[burntcopper]

This is entirely out of curiosity for those of you over the pond. Are there any names that're more likely to make you think 'huh, must be American/Canadian'? I'm only thinking this because I work with a thousand and one different nationalities and names a day - we've got to the point where we can make a reasonable guess at the person's nationality by their name alone, and the difference between English/Scots/Welsh/Irish names and those across the pond are very easy to spot if you're from these wind and rain swept isles. (eg, if someone's called Chelsea/Lucie/Dick/Chuck/anything with a Jr. on the end, there is no way in hell they're from the British Isles.) I can spot the non-Europeans, I just can't necessarily make a distinction between American and Canadian names.
