Actually I think that in the modern USA many more people would be familiar with the soap opera character
Dorian Lord than they would be familiar with
Dorian Gray. That may be sad, but it's true. Of course
Dorian Lord is not only a woman but is also the "bitch" character on her soap,
One Life to Live, so that's not necessarily a recommendation for the name:
