I think I've come across a Nichola or two; it's pretty uncommon though. When I was in Italy, people assumed I was a guy from my name, and in Germany I was always Nicole. I still get that here; I blame Nicole Kidman. ;-) At least it's better than Nicky; I hate that, just as NM does. My preferred shortened form is Nico.

I've yet to meet a female Lawrence or Lawrie.
