In Chapter 2 what information does Scout give Miss Caroline about the Cunninghams?

Scout tells Miss Caroline that Walter is a Cunningham, and thinks that explanation should be enough. After realizing Miss Caroline doesn't know what that means, Scout explains that the Cunninghams don't accept other people's help, and just try to get by with what little they have. Scout mentally recollects how Mr. Cunningham, when entailed, repaid Atticus for his legal services by giving the Finch family hickory nuts, stove wood, and other farm produce. The Cunninghams are farmers who don't have actual money now that the Depression is on.
