My mother's name is Dianne. However, everyone always leaves out the extra "n" and spells it "Diane", which can be quite annoying at times. But I still think it's a great name.
I'm not quite sure how famous she is, but JK Rowling's sister is named Dianne.

I find this dated and ugly although this view could be coloured by the fact that a Dianne I knew was the most nasty person I've had the misfortune to meet!
