Who are the Cunninghams in To Kill a Mockingbird?

The family is poor, they were hit hard as they are a laboring family (farmers). The family are proud as they are willing to starve than to lose their land, they also would not take something off someone that they could not pay back. Walter Cunningham Jnr for example would not take money off Miss Caroline. The Cunningham's are accepted and respected by the other children in the class and they are grateful of what they have.
They are a poor family of farmers who play a large role through out the story of To Kill a Mockingbird. They are first introduced when Scout beats up Walter Cunningham after the first day of school.
