Is Darlene a good name for this character?

Any name would be good for it. What you need to do, as a writer, is decide for yourself. When you think of this character, is it the only name that comes to mind? Try picking up a baby name book, or even looking online. Keep the character in mind while you're going through and see if any other names seem to jump out at you.

But, really, it's what you as the writer thinks is best.

I hope I helped. (:

You can't tell anything about a person by their name.

I knew 2 girls named Darlene, while growing up.

One of them was 5 yrs younger than me & lived next door, as a child, she bit me all the time.

The other one was a huge s.l.u.t. in High School & liked to date married men & teachers.

Lovely

It doesn't really matter what strangers on the internet think. You won't be writing anything if you feel the need to ask others things like this.

If the story is based in a white trash neighbourhood in south america than yeah its a good name

If that's what her mother named her, why not?

yes
