Reminds me of whisky, I'm afraid! I think that's mostly 'cos I'm a folky though. (http://www.youtube.com/watch?v=B12msT-dfBs). I also tend to think of Nancy from Oliver Twist. I believe the Camerons have a daughter by this name too. Objectively I should find it pretty, I guess, but the above associations colour it a little for me.
Whisky? Not heard of that one! And can't make link work. Other associations there don't really bother me. I'm just afraid of choosing a name people will laugh at or think is too weird. Does Nancy fall into this category?
The song is all about how the singer is beguiled by whisky in the same way as one might be by a woman and how he consequently ends up drunk and broke. But, like I say, only folkies would get the reference.
There are loads of little Nancies in SW London, and have been for a good few years now (I know 2 in yr 2 and several younger). It's not a name I particularly like (sorry), but as it's so popular these days I don't think anyone would find it a weird choice.
