Kat, "Kear-stie" is Scots pronunciation. "Kur-stie" is English. But in Britain you could expect to be called whichever, depending on what part of the country you're in at the time.

Now my name's fun - I've yet to find a European nationality apart from Brits that can pronounce it properly. :-) Grar-Ham, Gra-Ham, Gram, Graam - not a one that can say it Gray-am.

Graham.
