In To Kill a Mockingbird, where is Miss Caroline from?

We do not know exactly where in Alabama Miss Caroline is from - only that she is from Northern Alabama. We find this out in Ch. 2.

Although she is from the same state, she is clearly out of her element in this small, poverty stricken town. It is obvious that Miss Caroline is an outsider. She seems utterly disconnected from the first graders she is tasked with teaching. We see this throughout Ch. 2, where her efforts to teach are met either with unexpected results or unhappy ones.

For example, when she puts the alphabet on the board for the class she is surprised to see that everyone knows it already. She doesn't realize they know it because the majority of the students are repeating the first grade. Then, when she realizes Scout can read, she admonishes her for learning outside of school. All of these moments help to set up Miss Caroline as an outsider in Maycomb.
